Description

Air bag hemostasis device

Technical Field

The application relates to the technical field of medical equipment, in particular to an air bag hemostasis device.

Background

In daily life, wounds caused by the large impact force of sharp objects (such as knives) are generally irregular in shape, and can cause massive bleeding and even damage to various organs in the chest cavity in severe cases. If the patient cannot be timely treated, the patient can lose too much blood to cause shock and even death.

The main hemostatic means for such wounds are tourniquets and tamponade hemostasis methods in the prior art. The tourniquet achieves the effect of hemostasis by compressing the blood vessel to be in a blocking state, but the tourniquet can only compress the outside of the wound, so when the wound is deeper, the wound is easy to bleed, and the hemostatic effect is poor; the aim of stopping bleeding is achieved by filling and stopping the wound through cotton fabric, but the cotton fabric can absorb a large amount of blood and is not beneficial to quick hemostasis. In addition, when the wound is deep, the operation room is needed to be entered for operation observation so as to judge whether the organs in the thoracic cavity are damaged, the operation time is slow, and the correct treatment mode is not favorable for the patient to adopt in time.

Therefore, how to design a balloon hemostatic device to solve the above-mentioned deficiencies is a problem to be urgently solved by those skilled in the art.

SUMMERY OF THE UTILITY MODEL

An aim at of this application provides a simple structure, and the overall arrangement is ingenious, easy operation, and the effectual gasbag hemostasis device that just stanchs.

Meanwhile, in the process of screwing the locking sleeve, the fixing plate or the second air bag can be held by hands to prevent the second air bag from rotating.

Preferably, the end of the second air bag, which is offset from the first air bag, is fixed to the fixing plate. The advantages are that: since the fixing plate cannot be displaced in the radial direction of the sleeve, when the second air bag is fixed to the fixing plate, the second air bag is restricted from being displaced in the radial direction of the sleeve.

Preferably, the outer annular surface of the locking sleeve is provided with a non-slip part. The advantages are that: through antiskid portion can improve the hand with frictional force between the lock sleeve to avoid rotating to twist the in-process of lock sleeve takes place to skid.

Compared with the prior art, the beneficial effect of this application lies in:

(1) when the pressure hemostasis area formed between the first air bag and the second air bag can effectively stanch the inside and the outside of a wound by extending one end of the sleeve close to the first air bag into the chest cavity of a patient through the wound before the first air bag is not expanded, inflating the first air bag through the air inlet pipeline and moving the second air bag towards the first air bag; meanwhile, a seal is formed between the first air bag and the outer annular surface of the sleeve, so that blood on the wound can be effectively prevented from flowing into the chest cavity of the patient.

(2) Additionally, other surgical instruments (e.g., thoracoscopic probes) can also be inserted through the interior of the cannula and into the interior of the patient's chest to facilitate viewing of the interior of the patient's chest.
