Semi-surrounding pressing hemostasis device

Technical Field

The utility model relates to the field of medical supplies, in particular to a hemostatic device capable of avoiding completely blocking the blood supply of a far-end 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

The following description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings 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 protection scope of the present invention can be defined more clearly and clearly.

In order to avoid the occurrence of the phenomenon, the embodiment discloses a semi-enclosed pressing hemostasis device which comprises an external frame 1, a pressurizing bag 2, a limiting column 3, an arc-shaped pressing plate 4 and a positioning pin rod 5, wherein the external frame 1 consists of an n-shaped frame 11 at the top and arc-shaped plates 12 integrally connected to the bottom positions of two ends of the frame, the pressurizing bag 2 is fixedly connected between the two arc-shaped plates 12, the pressurizing bag 2 is communicated with an inflating air bag 6, a limiting hole 111 which is vertically communicated is arranged on a transverse plate at the top of the n-shaped frame 11, the limiting column 3 is connected in the limiting hole 111, the arc-shaped pressing plate 4 is arranged at the bottom of the limiting column 3, a limiting pin hole 31 which is communicated with the left side surface and the right side surface of the limiting column 3 is arranged on the body of the limiting column 3, a plurality of groups of positioning pin holes 112 are correspondingly arranged on the left and right side panels of the n-shaped frame 11 along the height direction of the n-shaped frame, and the positioning pin rods 5 pass through the positioning pin holes 112 on the n-shaped frame 11 and the limiting pin holes 31 on the limiting columns 3 to complete extrusion positioning.

In order to avoid the large amplitude of the limit column 3 in the limit hole 111 to shake to affect the pressing effect of the bottom arc-shaped pressing plate 4, the aperture of the limit hole 111 is matched with the diameter of the limit column 3.

In order to facilitate the hand holding, the top end of the limiting column 3 is provided with an end cap with the diameter larger than that of the limiting column 3.

In order to improve the fixing effect of the positioning pin rod 5, the aperture of the positioning pin hole 112, the aperture of the limit pin hole 31 and the diameter of the positioning pin rod 5 are matched.

The structure of the inflatable airbag 6 is similar to that of an airbag on the existing sphygmomanometer, and the inflatable airbag is mainly used for inflating and pressurizing the pressurizing bag 2, a first one-way valve is arranged on an air inlet pipeline of the inflatable airbag 6, the air outlet end of the inflatable airbag 6 is connected with the pressurizing bag 2, and a second one-way valve and an exhaust valve are arranged on a connecting pipeline between the air outlet end of the inflatable airbag 6 and the pressurizing bag 2. Can guarantee through first check valve and second check valve that the gas that gets into the gasbag carries out the inflation pressure boost of bag for one-way inflow, and the pressure boost is ended and is closed the check valve, opens discharge valve after the use and can discharge the gas in the pressure boost bag 2.

When the lower limbs of a human body are accidentally injured and a tourniquet needs to be bound at the proximal end of the limbs to compress blood vessels and block blood circulation for hemostasis, the hemostasis device is firstly sleeved on the thighs (the specific position is the position of the transverse finger of the knee 4), the pressurizing bag 2 is aligned to the femoral artery passing position on the thighs, then the limiting column 3 sleeved in the limiting hole 111 sinks to the arc-shaped pressing plate 4 to be attached to the surfaces of the thighs, the positioning pin rod 5 penetrates through the positioning pin hole 112 of the n-shaped frame 11 at the corresponding height and the limiting pin hole 31 on the limiting column 3 to complete extrusion positioning, then the first one-way valve and the second one-way valve are opened, the extrusion inflating air bag 6 inflates and pressurizes the pressurizing bag 2, and the pressurizing bag 2 presses the femoral artery to achieve hemostasis.

Because the hemostasis device under the working state only has the arc-shaped pressing plate 4 and the pressurizing bag 2 part which are in direct contact with the periphery of the thigh, and the rest part of the thigh is not directly pressed, the hemostasis device integrally realizes artery hemostasis in a semi-surrounding pressing mode, the blood supply and the venous return of the lower limb cannot be completely blocked, and compared with a tourniquet in the prior art, the hemostasis device cannot cause the problem of limb necrosis even being used for a long time.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
