As shown in fig. 3, in this embodiment, the negative pressure chamber is a pipe 5 with a circular cross section, the pipes 5 are arranged in a serpentine shape, and the pulling portion 2 is spherical. According to the utility model, through the arrangement of the snakelike pipeline 5, the negative pressure box is compact in structure while the movement stroke of the pulling part 2 is increased.

Through the setting of the blocking block 7, when more than two negative pressure traction components are used, the traction part 2 is effectively prevented from entering the negative pressure cavity of other negative pressure traction components, and the reliability of the skin tension reducing closer is improved.
As shown in fig. 3, in the present embodiment, in the use process of the skin stretching-reducing closer of the present utility model, the negative pressure connector 8 is connected with a negative pressure supply device, and the negative pressure supply device is communicated with the first chamber through a negative pressure inlet, and the negative pressure supply device is used for continuously providing negative pressure in the first chamber. Until the skin stretching wire closer of the present utility model is completed to be used, the negative pressure supply means is connected to the negative pressure joint 8, and the pulling force is continuously applied to the first adhesive sheet 1a and the second adhesive sheet 1 b. Therefore, the negative pressure connector 8 is provided with a lug, the lug is in a pawl shape, and when the negative pressure connector 8 is connected with the negative pressure supply device, the lug is used for limiting the negative pressure supply device to be separated from the negative pressure connector 8.
In other embodiments, the negative pressure inlet is detachably connected with the negative pressure supply device, and a pressure maintaining component is connected between the negative pressure inlet and the negative pressure supply device. Specifically, the pressure maintaining component can be arranged in the negative pressure box, and the pressure maintaining component can also be arranged outside the negative pressure box. In detail, the pressure maintaining component may be a valve disposed at the outer side of the negative pressure box, one side of the valve is connected with the negative pressure inlet, and the other side of the valve may be connected with the detachable negative pressure supply device. And when the negative pressure supply device is connected with the valve, the valve is opened, the negative pressure supply device is communicated with the first cavity, and the negative pressure supply device extracts air in the first cavity. When a negative pressure is formed in the first chamber and the connecting part 4 pulls the first adhesive sheet 1a and the second adhesive sheet 1b to close the wound, the valve is closed, the valve disconnects the first chamber from the negative pressure supply device, and then the negative pressure supply device can be disconnected from the valve. At this time, the first chamber is in a pressure maintaining state. In the pressure-maintaining state, one side of the pulling part 2 receives the suction force of the negative pressure, and the other side of the pulling part 2 receives the pulling force transmitted by the connecting part 4, and the two force directions are opposite. When the skin on two sides of the wound stretches, the tensile force transmitted by the connecting part 4 gradually decreases, so that the suction force of the negative pressure on one side of the pulling part 2 is larger than the tensile force transmitted by the connecting part 4, the pulling part 2 moves towards the direction away from the connecting part 4, so that the connecting part 4 is prevented from loosening, and continuous tensile force is further provided for the first adhesive sheet 1a and the second adhesive sheet 1 b. However, in the pressure-maintaining state, the gas in the first chamber is airtight, and the provided suction force is not constant. When the tensile force transmitted by the connecting portion 4 is too large, the pulling portion 2 moves toward the connecting portion 4 in excess of the magnitude of the suction force of the negative pressure, and the connecting portion 4 becomes loose. The effective movement stroke of the pulling part 2 is limited in the pressure-maintaining state, which is defined as a state in which an effective suction force can be provided to the pulling part 2 so that the connecting part 4 can provide a continuous pulling force to the first adhesive sheet 1a and the second adhesive sheet 1 b. Therefore, the skin stretching wire closer in the pressure-maintaining state needs to be used within the effective movement stroke of the pulling part 2.
As shown in fig. 1, 4 and 5, in this embodiment, the first adhesive sheet 1a and the second adhesive sheet 1b each include an adhesive backing 9 and a protrusion 10 located on the adhesive backing 9, where a first joint portion is provided on the protrusion 10, and the first joint portion is a card slot 11. The negative pressure box is provided with a second joint part, specifically the negative pressure box shell 6 is provided with a second joint part, the second joint part is specifically a first hook claw 12, and the first hook claw 12 can be detachably connected with the clamping groove 11 on the first adhesive sheet 1 a. A third joint part is arranged at the second end of the connecting part 4, the third joint part is a second hook claw 13, and the second hook claw 13 can be detachably connected with the clamping groove 11 on the second adhesive sheet 1 b. In the use process of the skin stretching-reducing closer of the embodiment, the first adhesive sheet 1a is fixed on the skin at one side of the wound, and the second adhesive sheet 1b is fixed on the skin at the other side of the wound; then the first hook claw 12 is connected with the clamping groove 11 on the first adhesive sheet 1a, and then the second hook claw 13 is connected with the clamping groove 11 on the second adhesive sheet 1 b; the negative pressure supply device is then connected to the negative pressure joint 8, and the connection portion 4 is gradually tightened by the negative pressure supply device, so that the first adhesive sheet 1a and the second adhesive sheet 1b are brought close to each other, and the wound is closed.
In other embodiments, the negative pressure case may be integrally formed with the first adhesive sheet 1a, and the second end of the connecting portion 4 may be integrally formed with the second adhesive sheet 1 b.
In this embodiment, as shown in fig. 5, the adhesive backsheet 9 is provided with a plurality of suture holes for skin ventilation or for fixing skin nails and sutures.
In summary, according to the present utility model, the negative pressure box provided with the negative pressure chamber is provided, the pulling portion 2 is provided to divide the negative pressure chamber into the first chamber and the second chamber which are not communicated with each other, the negative pressure box is connected to the first adhesive sheet 1a, the pulling portion 2 is connected to the second adhesive sheet 1b, the negative pressure is formed in the first chamber, the external air is introduced into the second chamber, so that the pressure difference is formed between the first chamber and the second chamber, thereby driving the pulling portion 2 to move, further providing continuous pulling force for the first adhesive sheet 1a and the second adhesive sheet 1b, and effectively solving the problem of weakening the pulling force of the adhesive sheets on both sides due to the skin extension on both sides of the wound.
