Description

Chain quick hemostasis device Technical field

The invention relates to the field of medical equipment, in particular to a chain type quick hemostasis device.

Background technique

Solving the problem of blood loss is still the most urgent problem to be solved in the current trauma treatment. According to relevant data, cases that cannot control a large number of blood loss account for 90% of the recoverable death cases.

At present, the use of tourniquets for hemostasis on the battlefield has disadvantages such as incomplete hemostasis, inconvenient operation, inability to use with one hand, difficulty in control and observation, and difficulty in causing severe pain or tissue damage. After the use of the currently installed tourniquet, the distal tissue is prone to ischemic injury, causing tissue necrosis, anaerobic infection leading to amputation and even life-threatening. The use of tourniquets on the battlefield is discouraged due to fear of limb necrosis.

It can be seen from the above that the control of blood loss at the joint of the trunk and limbs on the battlefield is still the focus of current research, especially when the main arteriovenous trauma in the groin area or the armpit is broken, the means available on the battlefield are extremely limited.

Generally, the wounds of gunshot wounds are irregular, especially the wounds caused by rifles. In the case of a gunshot wound in the inguinal region or at the axilla combined with major arteriovenous rupture, the existing local compression or the use of a tourniquet bandage to stop bleeding can not achieve the desired hemostatic effect.

Summary of the invention

The object of the present invention is to provide a chain type quick hemostasis device suitable for rapid hemostasis of war wounds, and is particularly suitable for rapid hemostasis of bullet wounds in the groin or axillary region.

The present invention is achieved by the following technical solution: a chain type rapid hemostasis device, characterized in that it comprises a plurality of hemostasis units for hemostasis of wounds; the hemostatic units are connected through a connecting line between the hemostatic units Concatenated into a hemostatic chain.

The invention has the characteristics of convenient carrying, and is particularly suitable for hemostasis of a bullet wound, and is therefore particularly suitable for war wound first aid, highlighting the special purpose of the field first aid object and application purpose, and is more suitable for the needs of war medical support; The hemostatic effect can reduce the incidence of complications of the tourniquet, and can appropriately extend the application time of the hemostatic device, and strive for a longer delivery time for graded treatment.

Its working principle and process are as follows:

When using, it only needs to quickly fill the wound with the hemostatic chain, and then properly seal and fix the surface of the wound, for example, the simple binding of the bandage, the application of the medical tape to the surface of the wound, etc., simple and efficient.

In order to better implement this solution, the following optimization schemes are also provided:

Further, a part of the hemostasis unit is composed of a water-swellable hemostatic block, and a part of the hemostasis unit is constituted by a functional capsule for assisting hemostasis.

Further, in order to further increase the effect of the hemostatic chain:

The functional capsule is one or any combination of a gas-filled decompression capsule inside, a dye-filled stained capsule inside, and an anti-inflammatory capsule filled with an anti-inflammatory drug.

Among them, the function of the decompression capsule is to adjust the compression force at the wound and the expansion of the blood clot to make room for preventing the tissue around the wound from being torn due to excessive expansion of the hemostatic block.

The role of the stained capsule is to stain the necrotic tissue near the wound so that the necrotic tissue of the wound can be debrided later, and the dye is usually selected from methylene blue;

The role of anti-inflammatory capsules is to prevent infection of tissues near the wound and to prevent wound infection.

In addition, the number of blood clots per 100 hemostasis units is usually 50-80, the number of decompression capsules is 5-10, the number of stained capsules is 5-10, and the number of anti-inflammatory capsules is 10- 20, here the hemostatic block and each functional capsule can be randomly connected in series or in a regular arrangement.

Further, in order to make the functional capsules more easily squeezed:

A thin walled region is disposed on an outer surface of the functional capsule.

The wall thickness of the thin-walled region is different from the wall thickness of the functional capsule in other regions to form a stress concentration region in the thin-walled region, so that the thin-walled region is more easily crushed when the hemostatic block expands and compresses the functional capsule.

Further, in order to facilitate the removal of the hemostatic chain from the wound during the post-debridement process, the tissue near the wound is not damaged:

Each of the hemostasis units is arranged in a wave shape, and each hemostasis unit is distributed at a peak or a trough;

The connecting line is made of an insoluble material, and soluble wiring is respectively connected between each adjacent odd number of hemostasis units from the first hemostasis unit at the beginning and between each adjacent even number of hemostatic units.

Here, this kind of scheme is specially designed for the wound caused by the bullet entering the body when the combat warrior is shot. Because the wound at the beginning of the bullet is usually a penetrating wound, and the wound is mostly irregular, the hemostatic chain will be Arbitrarily stacked into the wound surface, if the hemostatic unit is unevenly distributed, it is easy to block the wound, so it is not easy to take out the hemostatic chain during debridement at the later stage; and after each hemostasis unit is arranged in a wave shape, each hemostatic unit can be irregularly connected. Evenly arranged in the injured wound does not block the wound, which greatly facilitates the removal of the hemostatic chain from the wound.

At the same time, the purpose of the soluble wiring here is to make the hemostatic units always wavy before use, and when the hemostatic chain is put into the wound, the soluble wiring is melted by the blood, so each hemostasis is removed during the later debridement of the hemostatic chain. The units are connected in series so that they can be easily withdrawn from the wound.

Further, in order to facilitate rapid filling of the hemostatic chain to the large wound and to facilitate the later removal of the hemostatic chain from the wound without damaging the wound: the hemostatic chain is wrapped with a soluble bag.

Here, this scheme is specifically designed according to the different wound characteristics caused by the bullet to the local tissue. Because the wound at the injection end of the bullet usually has an explosive large wound, the wound area is severely hemorrhagic;

In the face of such bleeding, in order to achieve rapid hemostasis on the battlefield in the first time, each soluble bag body is filled with the same unit of hemostatic chain, so that each bag is made into a standard fast hemostatic bag, thus For the wound on the battlefield, a quick hemostatic bag is quickly filled, so that the wound is blocked at the first time and a good hemostasis effect has been achieved.

Further, in order to achieve more convenience, the hemostatic chain is filled into the wound: the hemostatic units are assembled into a bullet shape.

Compared with the prior art, the beneficial effects of the present invention are:

1. The invention adopts a connecting line to connect the hemostatic units in series to form a hemostatic chain, thereby greatly facilitating the removal of all the hemostatic units from the wound in the post-debridement work, and avoiding the single hemostasis unit remaining in the wound;

2. The invention can quickly and effectively block the wound caused by various guns, and is flexible and convenient to be fixed without being restricted by physiological structures, especially for arteriovenous hemorrhage in the groin area, which can quickly stop bleeding and does not cause Distal tissue ischemic injury;

3. The invention is especially suitable for war wound first aid, highlights the special purpose of the field first aid object and application purpose, and is more suitable for the needs of war medical support; it can achieve the hemostasis effect of the traditional means and reduce the incidence of operative complications of the tourniquet. , can properly extend the application time of the hemostatic device, and strive for a longer delivery time for graded treatment;

4. Using the invention to fill the wound surface, the wound surface of the bullet can be quickly and fully filled, so that the arteriovenous hemorrhage in the inguinal region can be quickly stopped, and the ischemic injury of the distal tissue is not caused.
