The present application uses high-pressure air to compress the wound, reducing the chance of the wound contacting the outside world. The protective cover can also be set above the wound. When the high-pressure air is injected, a vacuum can be drawn, and the vacuum negative pressure is used to tightly adsorb on the skin surface. According to the shape of the limb where the wound is located, it fits the skin, tightly adsorbs the skin and forms a seal for the protective cover, which solves the technical problem in the prior art that the wound is easily infected by bacteria. When the high-pressure air is injected, the skin can be pushed together, which solves the technical problem in the prior art that secondary damage is easily caused during wound compression treatment.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: This solution proposes a hemostatic device for hematology care, including a protective cover, the outer circumferential side wall of the protective cover is coaxially fixedly connected to a vacuum box, the protective cover has connecting holes in a ring array, the protective cover is connected to the vacuum box through the connecting holes, a partition plate is fixedly connected inside the vacuum box, the two side walls of the partition plate are longitudinally slidably connected with a push plate and a pull plate, one side of the bottom wall of the vacuum box is fixedly connected with a gathering pneumatic push rod in a ring array, and the other side of the bottom wall of the vacuum box is fixedly connected to an adsorption box.

[0007] Preferably, the partition plate symmetrically divides the internal cavity of the vacuum box into a positive pressure chamber and a negative pressure chamber, the positive pressure chamber is connected to the protective cover through a connecting hole, and the negative pressure chamber is connected to the adsorption box through a connecting hole.

[0008] As shown in the figure, the push plate and the pull plate are respectively arranged in the positive pressure chamber and the negative pressure chamber. The push plate and the top wall of the pull plate are fixedly connected with a connecting rope, and the connecting rope passes through the partition plate. The top wall inside the vacuum box is symmetrically fixedly connected with guide wheels, and the guide wheels are arranged on both sides of the partition plate. The connecting rope is arranged in contact with the guide wheels, and the top wall of the pull plate and the top wall inside the vacuum box are fixedly connected with a driving spring.

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] Example 1, as Figure 1-Figure 5As shown, the present invention proposes a hemostatic device for hematology nursing, comprising a protective cover 1, wherein the outer circumferential side wall of the protective cover 1 is coaxially fixedly connected to a vacuum box 2, the protective cover 1 is provided with connecting holes in an annular array, the protective cover 1 is connected to the vacuum box 2 through the connecting holes, a partition plate 21 is fixedly connected inside the vacuum box 2, and the two side walls of the partition plate 21 are longitudinally slidably connected with a push plate 301 and a pull plate 302, one side of the bottom wall of the vacuum box 2 is fixedly connected with a gathering pneumatic push rod 501 in an annular array, and the other side of the bottom wall of the vacuum box 2 is fixedly connected with an adsorption box 601.

[0028] like Figure 1-Figure 4 As shown, the partition plate 21 symmetrically divides the internal cavity of the vacuum box 2 into a positive pressure chamber 22 and a negative pressure chamber 23. The top wall of the vacuum box 2 is fixedly connected with an air intake valve and an exhaust valve. The air intake valve and the exhaust valve are connected to the positive pressure chamber 22. The positive pressure chamber 22 is connected to the protective cover 1 through a connecting hole. The negative pressure chamber 23 is connected to the adsorption box 601.

[0029] like Figure 1-Figure 4 As shown, the push plate 301 and the pull plate 302 are respectively arranged in the positive pressure chamber 22 and the negative pressure chamber 23, and the top walls of the push plate 301 and the pull plate 302 are fixedly connected with a connecting rope 303, and the connecting rope 303 passes through the partition plate 21, and the top wall of the vacuum box 2 is symmetrically fixedly connected with a guide wheel 305, and the guide wheel 305 is arranged on both sides of the partition plate 21, and the connecting rope 303 is in contact with the guide wheel 305. The top wall of the pull plate 302 is fixedly connected to the top wall of the vacuum box 2 with a driving spring 304. In the initial state, the push plate 301 is close to the top wall of the vacuum box 2, and the pull plate 302 is close to the bottom wall of the vacuum box 2.

[0030] like Figure 1-Figure 5 As shown, the bottom wall of the push plate 301 and the inner bottom wall of the vacuum box 2 are fixedly connected with a piston sleeve 502, and the base end of the piston sleeve 502 is connected to the base end of the gathering pneumatic push rod 501 through an air pipe.

[0031] like Figure 1-Figure 5 As shown, the output end of the piston sleeve 502 is fixedly connected to a push frame 505, and the bottom end of the push frame 505 is made of silicone material.

[0032] like Figure 1-Figure 5 As shown, the bottom wall of the adsorption box 601 is penetrated by an annular adsorption groove 602, and contact rings 603 fixedly connected to the bottom wall of the adsorption box 601 are provided on both sides of the adsorption groove 602. The contact rings 603 are coaxially arranged with the adsorption groove 602 and are made of silicone.

[0033] like Figure 1-Figure 2 As shown, the outer circumferential wall of the vacuum box 2 is symmetrically fixedly connected with a restraining airbag 7, and the restraining airbag 7 is connected to the positive pressure chamber 22 through a pipeline.

[0034] The wound site is disinfected and sterilized, the restraint airbag 7 is put on the patient's limb, and the protective cover 1 is placed on the wound site. High-pressure air is injected into the positive pressure chamber 22 through the air inlet valve. The high-pressure air drives the push plate 301 to approach the bottom of the vacuum box 2. The push plate 301 drives the connecting rope 303 to move on the guide wheel 305. The connecting rope 303 drives the pulling plate 302 to approach the top wall of the vacuum box 2, and at the same time compresses the spring 304. The high-pressure air enters the restraint airbag 7 through the positive pressure chamber 22. The inflated restraint airbag 7 presses the protective cover 1 on the limb. The protective cover 1 drives the vacuum box 2 and the adsorption box 601 to approach the limb, driving the contact ring 603 to press against the surface of the limb. The contact ring 603 made of silicone material fits against the skin on the surface of the limb, and at the same time, the bottom end of the push frame 505 contacts the skin.

[0035] When the pulling plate 302 approaches the top wall of the vacuum box 2, the pulling plate 302 draws a vacuum into the negative pressure chamber 23, and the skin is adsorbed by the adsorption groove 602 on the adsorption box 601. The contact ring 603 is firmly fixed to the skin and can also fit the shape of the limb surface, isolating the protective cover 1 from the external space, preventing bacteria carried in the air from infecting the wound;

[0036] When the push plate 301 approaches the bottom wall of the vacuum box 2, the piston sleeve 502 is compressed, and the air in the piston sleeve 502 enters the gathering pneumatic push rod 501. The annular gathering pneumatic push rod 501 drives the push frame 505 to move, and the push frame 505 pushes the skin around the wound to gather, avoiding the situation where the limb surface is compressed and the wound edge is torn. When the push plate 301 is located below the connecting hole on the protective cover 1, the high-pressure air in the positive pressure chamber 22 is injected into the protective cover 1 through the connecting hole. The high-pressure air compresses the wound, avoids bleeding from the wound, reduces tissue fluid exudation, and relieves local edema and inflammatory reactions.

[0037] When it needs to be removed, the exhaust valve is opened, and the high-pressure air in the vacuum box 2 is discharged through the exhaust valve, and the air in the restraint airbag 7 and the positive pressure chamber 22 is discharged, driving the spring 304 to reset, driving the pulling plate 302 close to the bottom wall of the vacuum box 2, and the pulling plate 302 drives the pushing plate 301 close to the top wall of the vacuum box 2 through the connecting rope 303, and the piston sleeve 502 is reset, and the piston sleeve 502 extracts the air in the gathering pneumatic push rod 501, and the gathering pneumatic push rod 501 drives the pushing frame 505 to reset, and the pushing frame 505 stops gathering the wound. When the pulling plate 302 is close to the bottom wall of the vacuum box 2, the pulling plate 302 stops extracting vacuum, and the adsorption box 601 no longer adsorbs the skin through the adsorption groove 602 and the contact ring 603. After the air in the restraint airbag 7 and the positive pressure chamber 22 is exhausted, the restraint airbag 7 and the protective cover 1 are removed from the patient's limb.

[0038] The above description of the present invention and its embodiments is non-limiting. The accompanying drawings are only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design of a structure and embodiment similar to the technical solution, they shall fall within the scope of protection of the present invention.
