Description

Hemostatic device

Technical Field

The invention relates to the field of medical supplies, in particular to a hemostatic device capable of avoiding completely blocking blood supply of a distal limb.

Background

When various accidental injuries are encountered, if the four limbs of a human body have artery rupture and bleeding, the bleeding speed is high due to high arterial pressure, the life can be threatened quickly if the hemostasis process is not timely effective enough, the tourniquet hemostasis is a simple and effective hemostasis method for emergency treatment of the great bleeding of the four limbs, and the hemostasis aim is achieved by pressing blood vessels to block the blood circulation. However, when the existing arterial tourniquet is used, the periphery of the limb needs to be continuously and seamlessly strongly pressurized, so that the effect of completely cutting off the blood supply and the venous return at the far end of the limb is achieved. The use of tourniquets is therefore limited, with a continuous time that is too long (45 minutes in the academic world, 2 hours in the U.S. legislation) risking necrosis of the distal limb, and serious and even requiring amputation.

Therefore, when the human condition is available, the indirect compression method is often used for hemostasis, but when the human condition is not available, for example, only the wounded person is on the spot, or other people cannot provide help and the external aid has a long time, it is very necessary to have a tourniquet capable of simulating indirect compression hemostasis.

Detailed Description

Preferred embodiments of the present invention will be described in detail below with reference to fig. 1-3, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.

Example 1

In order to avoid the occurrence of the phenomenon, the embodiment discloses a hemostasis device which comprises a limb overhead section and an air bag pressurization section, wherein the limb overhead section comprises a plurality of uniformly distributed arch rings 1 made of hard materials, the arch rings 1 are connected through a binding band 2, the air bag pressurization section comprises a pressurization bag 3 and an inflation bag 4, and the inflation bag 4 is connected with the pressurization bag 3; the built on stilts section one end of limbs is passed through bandage 2 and is connected with the one end fixed connection of pressure boost bag 3, the other end passes through buckle device 5 and can dismantle between pressure boost bag 3 and be connected.

The structure of the inflatable airbag 4 is similar to that of an airbag on the existing sphygmomanometer, the inflatable airbag is mainly used for pressurizing the bag 3, a first one-way valve is arranged on an air inlet pipeline of the inflatable airbag 4, the air outlet end of the inflatable airbag 4 is connected with the pressurizing bag 3, a second one-way valve and an exhaust valve are arranged on a pipeline between the air outlet end of the inflatable airbag 4 and the pressurizing bag 3, the air entering the airbag can be guaranteed to flow into the bag in a one-way mode through the first one-way valve and the second one-way valve, the one-way valve is closed after pressurization is finished, and the air in the pressurizing bag 3 can be discharged by opening the exhaust valve after the use is finished.

Buckle device 5 is common structure on the market, can have the multiple, concrete structure does not do the restriction, as long as can realize the joint connect and can adjust the function of connecting the elasticity can, use fig. 2 as an example, the buckle device disclosed in this embodiment mainly includes joint piece 51, buckle main part 52 and tighten up piece 53, joint piece 51 is connected with the one end of limbs built-up section through bandage 2, buckle main part 52 is connected with the one end of gasbag pressure boost section through bandage 2, tighten up piece 53 and connect and be used for tightening up of surrounding surface at bandage 2 free end, be equipped with the lock valve on buckle main part 52, be equipped with on the lock valve and pop out in buckle main part 52 according to joint piece 51 in the buckle device of button under the fastening state of being convenient for.

Example 2

This embodiment differs from embodiment 1 in that the structure of the arch ring 1 is further improved because when the device is used for hemostasis, the two end faces of the arch ring 1 abut against limbs in a vertical or near vertical state, pain may be caused to the human body when hemostasis is pressed, and in order to avoid this phenomenon, the two ends of the arch ring 1 are provided with arc transition sections 11.

The specific using method of the hemostatic device comprises the following steps:

when limbs of a human body are accidentally injured and a tourniquet needs to be bound at the proximal end of the limbs to press blood vessels and block blood circulation for hemostasis, firstly, a button on a locking valve is pressed to pop out a clamping block 51 from a buckle main body 52, then the hemostasis device is sleeved on a thigh 6 (the specific position is the position of a transverse finger of a knee 4) or the upper third position of an upper arm in a ring manner, a pressurizing bag 3 is aligned with the femoral artery passing position on the thigh or the 1/3 brachial artery passing position on the upper arm, then the clamping block 51 is connected with the buckle main body 52 in a clamping manner, a pulling and tightening block 53 tightly attaches the hemostasis device on the surface of the thigh or the upper arm of the human body, then a first one-way valve and a second one-way valve are opened, an inflating air bag 4 is pressed to inflate and pressurize the pressurizing bag 3, the pressurizing bag 3 presses the thigh or the upper arm artery to realize hemostasis, after use, the button on the locking valve on the, the clamping block 51 is automatically ejected, and the hemostatic device can be loosened and taken down.

Because the arch ring 1 on the hemostasis device in the working state is positioned on the periphery of the thigh 6 or the forearm in an arch bridge shape and is not in complete contact with the limb, the hemostasis device integrally realizes arterial hemostasis in a semi-surrounding pressing mode, the blood supply and venous return of the lower limb cannot be completely blocked, and compared with the tourniquet in the prior art, the hemostasis device cannot cause the problem of limb necrosis even being used for a long time.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
