Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly to a hemostatic device for treating internal bleeding caused by war trauma and a method for using the same. Background Art

[0002] Most chest and abdominal injuries from combat trauma are penetrating wounds or blind-tube wounds. These wounds are characterized by a small surface area but a deep wound, which can easily lead to internal organ damage and bleeding, and makes it difficult to determine the specific extent of the injury.

[0003] Traditionally, treatment for this type of internal bleeding involves emergency compression, including gauze packing. However, this approach is difficult to effectively stop bleeding in internal organs. Therefore, innovative and reliable internal bleeding control equipment is needed to address the challenges of stopping internal bleeding caused by penetrating chest and abdominal wounds and blind tube injuries from combat trauma. Summary of the Invention

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a hemostasis device for visceral bleeding caused by war trauma, comprising a plastic shell and an injection device; the plastic shell is a ring-shaped shell, the bottom of the plastic shell is provided with a cylindrical sponge, and a cylindrical chamber is provided inside the cylindrical sponge and the plastic shell; the top of the plastic shell is provided with a switch device, and the switch device is located directly above the cylindrical chamber; the bottom of the switch device is provided with a guide tube, and the guide tube is located in the cylindrical chamber; the outlet end of the injection device is located in the guide tube, and the injection end of the injection device passes through the switch device and is located outside the cylindrical chamber.

[0006] By adopting the above technical solution, a cylindrical sponge is provided so that the sponge can be inserted into the penetrating wound; by inserting an injection device into the guide tube, the hydrogel can be injected from the injection device into the cylindrical chamber and adhere to the wound through the cylindrical sponge; and by installing a switch device on the top of the plastic shell, the hydrogel can be prevented from overflowing from the cylindrical cavity.

[0007] The present invention is further configured as follows: the injection device includes a pressure injector and a connecting tube, one end of the connecting tube is located in the guide tube, and the other end of the connecting tube passes through the switch device and is connected to the outlet end of the pressure injector.

[0008] By adopting the above technical solution, one end of the connecting tube is inserted into the guide tube through the switch device, so that the injection device can be connected with the cylindrical chamber, so that the hydrogel or weak alkaline water can be injected into the cylindrical chamber and the outside of the cylindrical sponge, thereby achieving the effect of coagulation and degradation.

[0009] The present invention is further configured as follows: the switch device includes a switch housing and multiple elastic rubber petals, the switch housing is a hollow cylinder; one end of the multiple elastic rubber petals is fixedly connected to the inner wall of the switch housing, and the other end of the multiple elastic rubber petals is in contact with the outer wall of the connecting tube.

[0010] By adopting the above technical solution and arranging a plurality of elastic rubber petals in the switch housing, it is possible to achieve the effect that the connecting tube penetrates when inserted and seals when withdrawn.

[0011] The present invention is further configured as follows: the guide tube is a soft plastic tube, and the outer side wall of the guide tube is provided with a plurality of through holes.

[0023] 8) Remove the cylindrical sponge and suture the skin.

[0024] By adopting the above technical solution, the switch device uses multiple elastic rubber flaps, which can facilitate the insertion and extraction of the connecting tube and ensure that the cylindrical chamber is always in a sealed state; by pressing the side wall of the cylindrical sponge, the cylindrical sponge is inserted into the wound, so that penetrating wounds of different sizes can be filled, which is more adaptable; by injecting hydrogel, the inside of the wound can be quickly hemostatically adhered; after the injured person is transferred to the operating room, weak alkaline water is injected into the cylindrical chamber to quickly degrade the hydrogel, making it easier for medical staff to remove the entire sponge and perform subsequent surgical operations.

[0025] In summary, the present invention has the following beneficial effects:

[0026] 1. By setting up a cylindrical sponge, the sponge can be inserted into the penetrating wound;

[0027] 2. By inserting an injection device into the guide tube, the hydrogel can be injected from the injection device into the cylindrical chamber and adhere to the wound through the cylindrical sponge;
