Description

Burn and scald medicine spray film medicine bottle

technical field

The invention relates to the field of medicines, in particular to a film-sprayed medicine bottle for burn and scald medicine.

Background technique

Burns refer to tissue damage caused by heat, such as hot liquid, flame, red-hot metal, steam, high-temperature gas, electric energy, chemical substances, radiation, microwaves, etc. Exposure therapy is often used to treat large-area burns, and exposure therapy is often used to treat small-area burns. Scalds are treated with drug application or semi-exposure. Membrane is a new breakthrough in skin injury therapy in recent years. Membrane spray combines the advantages of membrane and spray patch to make a spray, which is sprayed on the skin, mucous membrane affected area and damaged surface to form a layer of soluble biofilm , prolong the residence time of the drug in the affected area, improve the efficacy of the drug, and save other dressings, so as to isolate and kill pathogenic microorganisms through a new physical and physiological dual antibacterial mechanism.

Currently on the market, spray film pharmaceutical bottles usually include a bottle body containing liquid medicine and a spray head, which can be connected by thread, bayonet or other means. Among them, the straw of the spray head is inserted into the bottom of the container, so as to ensure that the liquid medicine in the bottle can be utilized as much as possible. Existing commercially available sprays usually suck the medicinal liquid in the bottle into the straw by pressing the spray head to generate negative pressure. The spray dose sprayed by the spray head is fixed, and the sprayed dose cannot be adjusted freely. When the required dose is small, it will cause waste of liquid medicine. When the required dose is large, it needs to be pressed several times. The operation is more troublesome. In addition, since the spray head sprays the liquid medicine on the skin, it is usually a vertical spray, and the liquid medicine will rebound into the air on the skin surface, resulting in a waste of the liquid medicine.

Contents of the invention

The purpose of the present invention is to provide a burn and scald medicament film-spray medicament bottle capable of adjusting the spraying amount of the medicament liquid.

To achieve the above object, the present invention adopts the following technical solutions:

The burn and scald medicine spray film medicine bottle includes a bottle body. The bottle body includes a liquid storage cylinder, an air cylinder, a booster cylinder and a spray cylinder. The booster cylinder is equipped with a booster mechanism. A cylindrical mounting seat is connected in rotation, and the mounting seat extends out of the liquid storage cylinder. The outer edge of the mounting seat is tangent to the inner wall of the cylindrical shell, and a pressurized chamber is formed between the mounting seat and the cylindrical shell. The radial rectangular hole is slidably connected with the first supercharging vane and the second supercharging vane, an elastic member is connected between the first supercharging vane and the second supercharging vane, and the first supercharging vane and the second supercharging vane The free ends of the two pressurized blades are all in contact with the inner wall of the cylindrical shell, and the cylindrical shell is provided with a liquid inlet and a liquid outlet. side, and the caliber of the liquid inlet is larger than the caliber of the liquid outlet, and the liquid inlet is connected with the liquid storage cylinder; the air cylinder is provided with an air inlet, and the inside of the air cylinder is connected to a rotating shaft, and the rotating shaft is fixedly connected to a paddle, and the rotating shaft is connected to the A transmission mechanism is connected between the installation seats; a cylindrical screw is arranged inside the spray barrel, the outer edge of the cylindrical screw is attached to the inner wall of the spray barrel, and several nozzles are arranged at the free end of the spray barrel, and the nozzles communicate with the liquid outlet.

The working principle of this scheme is:

The liquid storage cylinder is used to store the liquid medicine, and the pressurizing mechanism is used to pressurize the liquid medicine so that the liquid medicine has sufficient pressure to be ejected from the nozzle to form a spray.

In the supercharging mechanism, the rotation of the mounting seat is used to drive the first supercharging vane and the second supercharging vane to rotate. When the first supercharging vane and the second supercharging vane rotate, the volume of the supercharging chamber on the side of the liquid inlet gradually increases. Large, negative pressure is generated, the liquid medicine is introduced into the liquid inlet cavity from the outside of the cylindrical shell through the liquid inlet, and with the rotation of the first booster vane and the second booster vane, it is discharged from the liquid outlet and enters the nozzle. On the one hand, because the diameter of the liquid outlet is smaller than that of the liquid inlet, on the other hand, when the first booster vane and the second booster vane rotate, the width of the booster chamber on the side of the liquid outlet gradually decreases, that is, the liquid outlet The volume reduction speed of the pressurized chamber on the side of the mouth is getting faster and faster, so the pressure of the liquid discharged from the liquid outlet is higher than the pressure of the liquid entering the liquid inlet, thereby realizing the pressurization of the liquid medicine.

The transmission mechanism is used for power transmission between the mounting base and the rotating shaft, so as to realize the rotation of the rotating shaft. The rotation of the rotating shaft is used to drive the blades to rotate and generate airflow in the air cylinder. There are multiple spiral channels, the airflow generated in the air cylinder enters multiple channels through the screw groove of the cylindrical screw, the screw groove of the cylindrical screw guides the airflow, and the airflow discharged from the end of the screw groove of the cylindrical screw is a spiral The shaped airflow blows the mist sprayed vertically from the nozzle into an oblique state, which reduces the impact force of the mist hitting the skin surface, so the rebound of the mist on the skin surface will be reduced.

Adopting this scheme can achieve the following technical effects:

1. By rotating the mounting seat, the first booster vane and the second booster vane can be driven to continuously rotate in the cylindrical shell, and the liquid medicine in the liquid storage tank is continuously sucked into the booster chamber and discharged through the nozzle, that is, it can be continuously discharged Therefore, the sprayed medicine amount can be adjusted according to the actual required medicine amount.

2. Through the rotation of the paddle and the guiding effect of the airflow through the screw groove of the cylindrical screw, the mist sprayed vertically from the nozzle can be blown into an oblique state, which reduces the impact force of the mist on the skin surface, so the mist is on the surface of the skin. The rebound formed on the skin surface will be reduced, that is, the waste caused by the liquid medicine rebounding into the air will be reduced.

3. The rotation of the mounting seat and the rotation of the rotating shaft can transmit power through the transmission mechanism, thus reducing the power mechanism.

4. By setting the diameters of the liquid inlet and the liquid outlet, and the structure of the first booster vane and the second booster plate in the booster mechanism, the booster effect is good.

Further, the transmission mechanism includes a bevel gear set, and the rotating shaft and the mounting seat are respectively connected with the bevel gear set. The number of teeth of the bevel gear set can be set as required, thereby changing the transmission ratio of the bevel gear set, and then changing the rotational speed of the rotating shaft, that is, changing the gas flow rate generated by the blades on the rotating shaft.

Further, a pressure valve is provided in the liquid outlet, and the pressure valve includes a "I" shaped baffle, and a spring is connected between the baffle and the liquid outlet. Only when the pressure of the liquid in the pressurized chamber on the side of the liquid outlet reaches the preset value, the pressure valve is opened, so as to prevent the liquid outlet from being opened when the liquid pressure is insufficient, which will cause the particle size of the mist sprayed by the nozzle to be too thick, resulting in dripping The phenomenon.

Further, the liquid inlet is connected with a straw, and the end of the straw is against the bottom of the liquid storage cylinder. The suction pipe can introduce the medicinal liquid in the lower part of the bottle body into the liquid inlet.

Further, the bottom of the liquid storage cylinder is inclined, and the bottom of the suction pipe is offset against the bottom of the liquid storage cylinder. When the medicinal liquid is used in a small amount, the medicinal liquid can still be effectively introduced into the liquid inlet.

Further, the bottom of the liquid storage cylinder is stepped, and the bottom of the straw is in contact with the depression at the bottom of the liquid storage cylinder. When the medicinal liquid is used in a small amount, the suction pipe can still effectively introduce the medicinal liquid into the liquid inlet.
