Abstract
The invention discloses an anti-failure air bag tourniquet which comprises a protective coat (1), an air pump interface (2) and at least two air bags, wherein a first air bag (3) and a second air bag (4) are communicated with each other, a hard tube with holes (5) is arranged between the first air bag (3) and the second air bag (4), and the tail end of the hard tube with holes (5) is connected with the air pump interface (2). The air pressure tourniquet adopts a double-air bag or multi-air bag structure, and the hard tube with the hole is arranged in the air bag, so that the tourniquet can effectively avoid the failure of the air bag caused by the pressing of the air bag in the inflating process or the sliding of the air bag tourniquet, and the normal operation of the trauma surgery can be ensured.
Description
Technical Field
The invention relates to an anti-failure air bag tourniquet, and belongs to the technical field of medical auxiliary equipment.
Background
The pneumatic tourniquet is a common device used in limb trauma surgery, and can obviously reduce wound bleeding in the surgery, thereby ensuring clear surgical field, easily identifying various tissues and being convenient for surgical operation.
At present, the most common is the electric pneumatic tourniquet, and the structure of the used air bag tourniquet is very simple, the outer surface is a protective sleeve 1, the inner side is an air bag 8, and the air bag 8 is connected with an air pump through a pipe 2 (as shown in figure 2). When the tourniquet is used, the tourniquet is wound on a limb, the air pump is used for inflating the air bag and keeping the pressure constant, and the tourniquet is used for providing a pressure for the limb to block the blood flow in the blood vessel, so that the function of hemostasis in limb distal end operation is achieved. However, the tourniquet has the defects of easy failure, and the defects of insufficient pressure of the tourniquet on limbs (the pressure maintained by the air pump is normal), poor hemostasis effect and even more serious bleeding than the tourniquet (the vein wall is thinner than the artery wall, the vein is blocked when the pressure is insufficient, the artery is not blocked, and the blood backflow is limited). The main reasons for the failure of the pneumatic tourniquet are: the balloon tourniquet is not tied tightly. And is easily disabled if not tightened. Through analysis and experiments, the reason that the air pressure tourniquet which is not tightly bound fails is that the outer layer air bag is pressed closed in the inflating process (as shown in figure 3), and air cannot enter the air bag, so that the inner layer air bag fails due to insufficient pressure. In addition, it is found that clinically, as the diameter of the thigh of some patients is thick at the top and thin at the bottom, the thigh is in a cone shape (as shown in fig. 4), when the air bag is inflated, the air bag tourniquet can slide towards the far end (with small diameter) of the thigh due to pressure, and the air pressure tourniquet can be not tight enough, so that the tourniquet can fail. Causes of balloon tourniquet slippage: the gasbag tourniquet that uses at present is single gasbag structure, and the shape after the gasbag tourniquet aerifys is cylindrical, does not match with toper thigh shape, and the pressure that forms after the single gasbag tourniquet aerifys is everywhere uneven simultaneously, and the biggest point is located in the middle of the gasbag, consequently slides easily, causes the tourniquet inefficacy.
Disclosure of Invention
The invention aims to solve the technical problem of providing an anti-failure air bag tourniquet, thereby overcoming the defects of the prior art.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows:
the utility model provides a prevent losing effect gasbag tourniquet which constitutes including protective sheath, air pump interface and two at least gasbags, intercommunication each other between the first gasbag in two gasbags and the second gasbag be provided with foraminiferous hard tube between first gasbag and the second gasbag, the tail end of foraminiferous hard tube with the air pump interface be connected.
Preferably, in the above-mentioned anti-failure balloon tourniquet, the first balloon and the second balloon are communicated through a communicating tube between balloons.
Preferably, the side wall of the hard tube with the hole is provided with a plurality of vent holes.
The invention has the beneficial effects that: compared with the prior art, the invention has the following characteristics:
1. according to the invention, the hard perforated hard tube is arranged in the air bag, the tail end of the perforated hard tube is connected with the air pump interface of the air bag, when the tourniquet is used, air is filled into the air bag through the perforated hard tube, even if the air bag is pressed to be closed due to pressure, the air can still reach all parts of the air bag through the perforated hard tube, the action of the tourniquet is similar to that of a drainage tube, and thus the tourniquet is prevented from being failed due to the fact that the air bag is pressed to be closed in the inflating process.
2. The invention changes the air sac from the single air sac of the prior art into a double-air sac or even multi-air sac structure, and the air sacs are communicated through the pipe (communicating pipe between the air sacs) (communicating principle).

Detailed Description
The invention is explained in more detail below with reference to the drawings and examples.
Example 1: as shown in fig. 1 to 6, the failure-prevention air bag tourniquet comprises a protective coat 1, an air pump connector 2 and two air bags, wherein the structures of the protective coat 1 and the air pump connector 2 are the same as those of the prior art. The first air bag 3 and the second air bag 4 of the two air bags are communicated with each other through the inter-air bag communication pipe 6, so that the free flow of the inflating gas between the first air bag 3 and the second air bag 4 is ensured, and meanwhile, the first air bag 3 and the second air bag 4 are inflated and the pressure is kept constant.
A hard tube with holes 5 is arranged between the first air bag 3 and the second air bag 4, the hard tube with holes 5 is made of hard materials, and a plurality of vent holes 7 are arranged on the side wall of the hard tube with holes 5. The tail end of the hard tube with the hole 5 is connected with the air pump interface 2. The air filled into the air bag from the air pump interface 2 firstly enters the perforated hard tube 5, and the first air bag 3 and the second air bag 4 are inflated through a plurality of vent holes 7 on the side wall of the perforated hard tube 5.
What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept herein, and it is intended to cover all such modifications and variations as fall within the scope of the invention.
