Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment and relates to an air bag type tourniquet with a built-in lining plate. Background Art

[0002] A tourniquet is an essential device for orthopedic limb surgery and first aid for limb vascular injuries. When in use, the tourniquet is generally wrapped around the limbs, and then the airbag in the tourniquet is inflated to obtain pressure. When the pressure is sufficient, the blood flow can be stopped. In order to obtain more uniform pressure, a lining plate can be set in the airbag tourniquet. For example, Chinese utility model patent CN201147348Y (announcement date: 2008-11-12) discloses a pressure-equalizing airbag tourniquet, including a canvas bag with a cloth belt and a rubber airbag therein, characterized in that it also includes a PVC board in the canvas bag, and the PVC board is a strip-shaped board with two long sides that are in parallel arcs that match the rubber airbag. The beneficial effect of the utility model is that the airbag pressure is uniform and lasts for a long time, so that complex limb surgery can be completed within the duration of a single tourniquet. After being wrapped or curled, it is conical, suitable for the shape of the limbs, and not easy to slip off. When performing limb surgery or emergency transportation for limb vascular injuries, the use of the airbag tourniquet can reduce the inflation pressure of the tourniquet airbag, extend the duration of the tourniquet, and reduce the occurrence of complications such as nerve damage. The disadvantage is that the PVC board is easy to move in the canvas bag, affecting the use effect. Utility Model Content

DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the accompanying drawings. Figure 1-2 :

[0021] A pneumatic tourniquet with a built-in lining, comprising a belt body 1, a barbed buckle 2, a wool buckle 3 and an inflation nozzle 4, an airbag cavity connected to the inflation nozzle 4 is formed in the belt body 1, and the inflation nozzle 4 is connected to an air supply device through an air pipe, the belt body 1 comprises an upper cloth layer 5, a lining plate 6 and a lower cloth layer 7 arranged in sequence, the upper cloth layer 5 and the lower cloth layer 7 are pressed and fixed, the lining plate 6 and the upper cloth layer 5 are pressed and fixed, a first indentation 8 produced by pressing the upper cloth layer 5 and the lower cloth layer 7 is circumferentially arranged along the outer edges of the upper cloth layer 5 and the lower cloth layer 7, the first indentation 8 is arranged around the outside of the lining plate 6, and a second indentation 9 produced by pressing the lining plate 6 and the upper cloth layer 5 is distributed along the length direction of the belt body 1, and the gap between the upper cloth layer 5, the lining plate 6 and the lower cloth layer 7 forms the airbag cavity.

[0022] When in use, the belt body 1 is wrapped and tied to the limbs using the barbed buckle 2 and the wool buckle 3, and then the airbag cavity is filled with gas to a certain pressure through the blowing nozzle to achieve the effect of hemostasis. During use, since the lining plate 6 is fixed to the upper cloth layer 5, it will not shift, and the lining plate 6 and the airbag work together to ensure that the pressure is always uniform.

[0023] In this embodiment, the pressing is performed by heat pressing or ultrasonic pressing.

[0024] In order to form a more uniform airbag cavity, a gap for gas to pass is left between the lining plate 6 and the first indentation 8, and the airbag cavity is distributed in the area between the lower fabric layer 7 and the lining plate 6, the area between the lower fabric layer 7 and the upper fabric layer 5, and the non-pressed area between the upper fabric layer 5 and the lining plate 6.

[0025] The second indentations 9 are arranged in parallel and spaced apart. In this embodiment, there are three second indentations 9, which are respectively located on both sides and the middle of the lining plate 6.

[0026] The width of the first indentation 8 and the second indentation 9 is 2 mm to 4 mm. Preferably, the width of the first indentation 8 and the second indentation 9 is 3 mm.

[0027] In this embodiment, the upper fabric layer 5 and the lower fabric layer 7 are made of PU material, and the lining plate 6 is made of PE material.

[0028] The upper fabric layer 5 and the lining plate 6 are respectively provided with a first through hole 10 and a second through hole 11 for the inflation nozzle 4 to pass through, and the gas outlet of the inflation nozzle 4 is provided on the side of the lining plate 6 opposite to the lower fabric layer 7. Furthermore, the inflation nozzle 4 is fixedly connected to the upper fabric layer 5 by pressing. Through the above arrangement, the gas can be firstly filled into the cavity between the lining plate 6 and the lower fabric layer 7, and since the cavity is the largest part of the airbag cavity, the smooth inflation can be ensured.

[0029] This embodiment further improves the structure of the hair button 3 and the spike button 2. The hair button 3 and the spike button 2 in this embodiment do not use the traditional sewing structure. The specific structure is: the hair button 3 is bonded to the upper cloth layer 5, and the spike button 2 is provided with a third through hole 12 for the inflation nozzle 4 to pass through. The spike button 2 is hung on the inflation nozzle 4 through the third through hole 12, and the spike buttons 2 on both sides of the inflation nozzle 4 form a fixed connection end 13 and a movable connection end 14 respectively. Before use, the fixed connection end 13 is bonded to the hair button 3, and after being wrapped around the limbs, the movable connection end 14 is bonded to the hair button 3 to tighten the tourniquet.

[0030] A binding belt 15 is sewn on one end of the belt body 1 opposite to the inflation nozzle 4 .

[0031] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
