Device for pushing granular hemostatic to relatively deep wound

Abstract

The invention discloses a device for pushing a granular hemostatic to a relatively deep wound. The device comprises a cylindrical outer-layer barrel with a closed front end and an open rear end. The device is characterized in that an inner-layer barrel is arranged in the outer-layer barrel; the outer diameter of the inner-layer barrel is consistent with the inner diameter of the outer-layer barrel; the inner-layer barrel and the outer-layer barrel are matched with each other and can slide relatively; an inner cavity of the barrel is a hemostatic accommodating space; and two ends of the inner-layer barrel are open. The front end of the outer-layer barrel is in a conical design; the outer-layer barrel is integrally machined into a plurality of fan-shaped petal bodies through cutting or injection molding; all the petal bodies are in thin-wall connection or seamless connection; and when axial force is applied to the inner-layer barrel, the petal bodies on the outer-layer barrel can be stressed to be in an open state. A plug at the rear end part of the inner-layer barrel is pulled out, and the hemostatic in the barrel can be quickly pushed out by inserting an injection rod into the inner-layer barrel and applying pressure. The discharging end of the barrel is easier to open, so that smooth injection of the hemostatic is guaranteed, and it is guaranteed that the efficacy of the hemostatic is brought into full play to the maximum extent.

Description

technical field [0001] The invention relates to a medical device, in particular to a device for pushing granular hemostatic agents to deep wounds, and belongs to the technical field of medical first aid. Background technique [0002] When the human body is externally injured, if the wound is not treated quickly or correctly, profuse bleeding may occur, and even fatal danger may occur. Military data show that approximately 50% of combat casualties in armed conflict are due to blood loss, and that most die within thirty minutes of injury, with approximately 60% dying within the first five minutes. Gunshot wounds are relatively common external traumas in armed conflicts. The wounds are deep and the blood loss is fast. Therefore, timely hemostasis of wounds can greatly reduce casualties. Since gunshot wounds and stab wounds are special, the external wounds are few and have a certain depth, conventional external hemostatic materials cannot go deep into the wounds, so a hemostati...

Problems solved by technology

[0005] The disadvantages of the above-mentioned prior art are: firstly, the barrel of the device in the prior art is a single-layer design, and the valve body at the front end of the device is opened by the power transmitted by the hemostatic agent. This opening method causes the hemostatic agent to be squeezed and compressed, destroying The original form of the hemostatic agent prevents the hemostatic agent from fully contacting the blood, which affects the liquid absorption performance of the hemostatic agent, thereby affecting the hemostatic effect; secondly, the conduction force provided by the hemostatic agent is limited, and the valve body at the front end of the device cannot be fully opened, and the hemostatic agent cannot Rapid release affects the hemostatic effect; again, as mentioned above, due to the restriction of the hemostatic agent conduction, in order to realize its bolus injection function, the existing technology generally needs to set the gap between the valve bodies relatively wide, so although it can barely The hemostatic agent is pushed out, but the wide gap of the valve body of the device leads to poor rigidity of the front end of the device, making it difficult to insert into the wound, and the wide gap of the valve body of the device causes blood to flow into the device during the process of the device being in place, causing the hemostatic agent to adhere and gather at the opening, making it difficult to push out problem, can not achieve the purpose of first aid
