Description

Device for pushing granular hemostatic to deeper wound

Technical Field

The invention relates to a medical instrument, in particular to a device for pushing a granular hemostatic to a deep wound, and belongs to the technical field of medical first aid.

Background

If the wound is not quickly or properly treated when the body is externally injured, massive bleeding may occur, even with fatal danger. Military data show that about 50% of combat casualties in armed conflicts are due to blood loss, and most die within thirty minutes after injury, with about 60% dying within the first five minutes. Gunshot wounds are common external wounds in armed conflict, and are deep in wounds and high in blood loss speed, so that bleeding can be stopped for the wounds in time when the wounds are injured, and casualties can be greatly reduced. Because the gunshot wound and the stab wound are special, the external wound is less, the external wound has a certain depth, and the conventional external hemostatic material cannot penetrate into the wound, a hemostatic technical means which can be directly inserted to contact with a bleeding point is needed.

Like the utility model patent of publication No. CN 205924682U, the publication date is 2017 2 month 8 days, the name is "a cylinder hemostasis device", just disclose a technical means that can get into the point of bleeding and carry out hemostasis, it includes cylindrical barrel, the barrel rear end of barrel is uncovered, the barrel front end of barrel is the discharge end, the discharge end includes circular shape bottom plate, the bottom plate all around with barrel seamless connection or integrated into one piece, the bottom plate includes a plurality of sectorial lamella bodies, connects or connects through thin wall connection or seamless concatenation between the adjacent lamella body through a plurality of tie points. The utility model provides a different length and different diameters can be made to the cylinder hemostasis device, can insert the wound or the incision of different diameters, in time pushes into the position of bleeding of relative darker with hemostatic, and need not enlarge the wound through the operation.

Also disclosed is a powder hemostatic propeller for human cavity wounds, as claimed in the invention patent application with publication number CN 108888843 a, entitled "powder hemostatic propeller for human cavity wounds", comprising a barrel and a propelling component, wherein the barrel comprises a connected barrel section and a piercing section, and the radial dimension of the piercing section is gradually reduced from one end connected with the barrel section to one end far away from the barrel section; in the injection state, the powdered hemostatic agent in the barrel is squeezed out of the piercing section by means of the pressure exerted by the piston head.

The defects of the prior art are as follows: firstly, the cylinder body of the device in the prior art is designed in a single layer, the valve body at the front end of the device is opened by means of the conduction power of the hemostatic agent, and the hemostatic agent is extruded and compressed in the opening mode, so that the original form of the hemostatic agent is damaged, the hemostatic agent cannot be fully contacted with blood, the liquid absorption performance of the hemostatic agent is influenced, and the hemostatic effect is further influenced; secondly, the conduction force provided by the hemostatic agent is limited, the valve body at the front end of the device cannot be fully opened, and the hemostatic agent cannot be quickly pushed out, so that the hemostatic effect is influenced; thirdly, as mentioned above, due to the restriction of the conductivity of the hemostatic, in order to realize the function of injecting the hemostatic, the gap between the flap bodies generally needs to be set wider in the prior art, so that although the hemostatic can be reluctantly pushed out, the wider gap between the flap bodies of the device causes poor rigidity of the front end of the device and is not easy to insert into a wound, and the wider gap between the flap bodies of the device causes the blood to flow into the device in the process of positioning, so that the hemostatic is adhered and gathered at the opening, which aggravates the problem of difficult pushing out, and the purpose of first aid cannot be achieved.
