Description

Injection venography ring

technical field

The utility model relates to a developing device for intravenous injection, which belongs to the medical field.

Background technique

In hospitals, basically all patients need blood tests or intravenous injections, and the prerequisite is that medical staff need to find blood vessels, but for infants, the elderly, or patients with thin blood vessels or thick fat layers, it is very difficult for medical staff to find blood vessels. It is difficult to ensure that blood vessels are found at one time, which causes great difficulties for blood drawing and intravenous injection, which not only causes pain for patients, but also easily leads to medical disputes. It is also difficult to guarantee the success rate for patients with reduced blood vessels and collapsed blood vessels. For such patients, it is obviously impractical to cut blood vessels and place intravenous indwelling needles, and X-rays or B-ultrasound cannot be used for injections. , At the same time, the radiation of X-rays is large, which is not good for patients and medical staff.

Therefore, it is necessary to need a device that can quickly visualize blood vessels to ensure the success of intravenous injection. The traditional structure of the developing device, such as the Chinese patent 201010162032.3 blood vessel developing device, makes blood vessels visualize through infrared rays. It is also harmless to patients and medical staff, but due to the large size of the device, the first problem is that it is inconvenient to carry, especially in wards and emergency rooms, it is difficult to ensure a fixed position. Due to the complex structure of a type of developing device, it is difficult for ordinary hospitals to have large capital investment to purchase this type of commonly used medical equipment. At the same time, the maintenance of equipment is also a big problem, especially in the injection room where there are many people and complicated. , work-intensive places are easy to bump into, so it is not conducive to the promotion and use of medical institutions;

The technology disclosed in the Chinese patent 201220202671.2 blood vessel imaging surgery headlight also uses infrared rays to visualize blood vessels, but first of all, this technology is used for surgery, not specifically for intravenous injection. At the same time, the light-emitting unit disclosed by this technology When used, it is far away from the patient's body, and the clarity of vascular imaging cannot be well guaranteed, so it is also problematic to use.

Utility model content

The utility model aims to provide a vein developing ring for injection which has a simple and reasonable structure, can visualize blood vessels during blood drawing and venipuncture, and is harmless to patients and medical staff, so as to overcome the shortcomings of the prior art.

The technical scheme that the utility model realizes its purpose is:

A vein developing ring for injection, comprising a light emitting unit and an arc-shaped spring piece, one side of the arc-shaped spring piece is fixed with a connecting rod, the end of the connecting rod has a joint ball head, the light emitting unit includes a lamp holder, a lamp holder Several sets of relative infrared LED light sources are installed on the seat, and the rear end of the lamp holder is also connected with a storage chamber for a battery that supplies power to the infrared LED light source. The end of the tube has a joint cavity that matches with the joint ball head, and through the cooperation between the joint ball head and the joint cavity, the light emitting unit is fixed on the arc-shaped spring piece.

The adjustment hose is a metal hose.

The outer surface of the lamp holder has protrusions arranged oppositely, and the light-gathering ring is clamped on the lamp holder through the protrusions.

After adopting the above structure, due to the arc-shaped spring sheet, a connecting rod is fixed on one side surface of the arc-shaped spring sheet, and the end of the connecting rod has a joint ball head, and the structure of the arc-shaped spring sheet is similar to a tape measure used by students The strap of the watch has a curvature on one side and a concave side. As long as you tap the curved side to any knuckle of the medical staff, the curved spring piece can be fastened and fixed like a ring. The advantage of this structure is that, The utility model is not only easy to wear, but also convenient for medical staff to use in busy work, and at the same time, it can adapt to the hands of different medical staff and can be used universally.

The light-emitting unit includes a lamp holder, on which several groups of relative infrared LED light sources are installed, and the rear end of the lamp holder is also connected with a storage cavity for a battery that supplies power for the infrared LED light source, and the end of the storage cavity has a rear cover, so that The advantage of the structure is that in use, it is preferable to use an infrared LED light source that can emit near-infrared light. Since the red protein in human blood has a strong ability to absorb infrared light, and the surrounding tissue is weak, it is near-infrared. Under the irradiation of infrared light, it is possible for the medical staff to find the veins more clearly. At the same time, the light-emitting unit includes a lamp base, an accommodation cavity and a rear cover, which is similar to the simplest structure of a flashlight. When the battery is placed in the accommodation cavity, And cover the back cover, when the circuit is connected, the infrared LED light source will emit near-infrared light.

The back cover has an adjustment hose, and the end of the adjustment hose has a joint cavity that matches the joint ball head. Through the cooperation between the joint ball head and the joint cavity, the light-emitting unit is fixed on the arc-shaped spring piece. The advantage of this structure is that it emits light The unit can not only be fixed on the arc-shaped spring piece, but also due to the cooperation of the joint ball head and the joint cavity, the light-emitting unit can also adjust the rotation angle and position, which is convenient for medical staff to adjust to the best use position during use.

The adjustment hose is a metal hose. After the approximate position of the light-emitting unit is adjusted, the adjustment hose can be bent to make the light-emitting unit as close to the patient’s skin as possible, so as to maximize the visualization of the veins and ensure Success rate.

The outer surface of the lamp base has relatively arranged protrusions, and the focusing ring is clamped on the lamp base through the protrusions. When the use time is daytime or when the light is strong, the focusing ring can be clamped on the lamp base. The infrared light emitted by the infrared LED light source is gathered, and the use effect is better.

Compared with the prior art, the utility model has self-evident benefits. Firstly, the medical staff can wear the utility model in the working state without affecting the normal work. At the same time, they can also wear it according to personal habits. On any finger, it will be more comfortable for medical staff to use, and when in use, the light-emitting unit is originally located in the hand of the medical staff, which is already very close to the patient's skin, and through adjustment, the light-emitting unit can be as close as possible. It ensures that the veins can be visualized to the maximum, which can not only speed up the work efficiency of medical staff, reduce the pain of patients, but also not easily induce doctor-patient disputes. At the same time, the structure of the utility model is relatively simple, and maintenance is also convenient, which is convenient for large-scale adoption.
