Description

Technical Field

[0001] The present invention relates to the technical field of drainage devices, and in particular to a clamping subcutaneous drainage device. Background Art

[0002] Clinically, there are generally two situations where drainage needs to be placed: the first is when the clean incision wound is large and deep, and in order to prevent hematoma formation, a negative pressure drainage device needs to be placed for drainage before the incision is closed; the second is when the incision is infected and an abscess is formed, and the abscess is drained. In the first case where drainage needs to be placed, it is necessary to make another incision on the skin in addition to the original incision to suture and fix the drainage device to prevent air leakage in the surgical cavity from forming negative pressure or the negative pressure device from falling off. Suturing and fixing the drainage device by making another incision on the skin will cause additional damage to the patient. In the second case where drainage needs to be placed, the drainage device often falls out with the dressing during dressing changes. Repeated placement of the drainage device will cause pain to the patient, especially the fear and crying of child patients, which increases the psychological burden on the patient and also increases the workload of medical staff. Summary of the Invention

[0003] In view of the defects in the prior art, the present invention provides a clamping subcutaneous drain. Using this device, the drain can be clamped and fixed on the skin. It is easy to use and can reduce the patient's pain and the workload of medical staff.

[0004] A clamping subcutaneous drainage device includes a drainage tube and a spring clip. The drainage tube passes through the spring clip. A slide groove is opened on the outer circumferential wall of the drainage tube. The slide groove is distributed axially along the drainage tube. A slider is slidably connected in the slide groove. The fixed axis of the spring clip is connected to the slider through a connecting rod. The slider can be fixed at any position in the slide groove through a limiting device.

[0005] In order to solve the above problems, the inventors designed the present technical solution, in which a sliding groove is opened on the outer circumferential wall of the drainage tube, and the sliding groove is distributed along the axial direction of the drainage tube. The slider can slide in the sliding groove to adjust its position. When the slider slides to the appropriate position, it is fixed by a limiting device. The drainage tube passes through the spring clip, and the slider is connected to the fixed axis of the spring clip through a connecting rod. When in use, for example, an opening is made on the abscess, and then the front end of the drainage tube is inserted into the abscess, and then the slider is moved to the appropriate position, fixed by the limiting device, and then clamped on the abscess skin and the drainage tube with the spring clip for fixation. Since the abscess skin also needs to be treated later, the spring clip will not have any effect even if it damages the skin. With this fixing method, dressing change is simple. When changing the dressing, just loosen the spring clip to change the dressing. After changing the dressing, it can be re-clamped on the abscess skin. For the first situation where drainage needs to be placed, the spring clip is clamped on the skin without the need to make another incision on the skin to suture and fix the drainage device, reducing the patient's pain and the workload of medical staff.

[0006] Preferably, the limiting device is a cable tie, which is tied to the drainage tube and the slider to fix the slider at any position in the chute. In this technical solution, the limiting device is a cable tie, which is tied to the drainage tube and the slider to fix the slider at any position in the chute. The cable tie fixation is simple and convenient.

[0007] Preferably, the inner wall of the spring clamp is provided with a plurality of ridges. In this technical solution, the inner wall of the spring clamp is provided with a plurality of ridges, and the inner wall of the spring clamp refers to the wall that contacts the skin when the spring clamp is clamped on the skin. The plurality of ridges contacting the skin make the clamping of the spring clamp more stable.

[0008] Preferably, the splint of the spring clip is made of medical hard plastic.

[0009] Preferably, the rear end of the drainage tube is connected to a drainage bag. In this technical solution, the rear end of the drainage tube is connected to a drainage bag to facilitate the collection and processing of drainage material.

[0010] Preferably, a negative pressure suction ball is connected between the drainage tube and the drainage bag. In this technical solution, a negative pressure suction ball is connected between the drainage tube and the drainage bag, and the negative pressure generated by the negative pressure suction ball is used for drainage, which has a better drainage effect.

[0011] Preferably, the drainage tube is made of soft silicone. In this technical solution, the drainage tube is made of soft silicone, and the insertion or removal process is basically painless.

[0012] Preferably, the outer surface of the slider is an arc surface, and the arc surface and the outer circumferential wall of the drainage tube are on the same circumference. In this technical solution, the outer surface of the slider is an arc surface, and the arc surface and the outer circumferential wall of the drainage tube are on the same circumference, making the device overall beautiful.

[0013] The beneficial effects of the present invention are embodied in that: in the present technical solution, a slide groove is opened on the outer circumferential wall of the drainage tube, and the slide groove is distributed along the axial direction of the drainage tube. The slider can slide and adjust its position in the slide groove. When the slider slides to the appropriate position, it is fixed by a limit device. The drainage tube passes through the spring clip, and the slider is connected to the spring clip fixing shaft through a connecting rod. When in use, for example, an opening is made on the abscess, and then the front end of the drainage tube is inserted into the abscess, and then the slider is moved to the appropriate position, fixed by the limit device, and then fixed on the abscess skin and the drainage tube by the spring clip. Since the abscess skin also needs to be treated later, the spring clip will not have any effect even if it damages the skin. The dressing change is simple with this fixing method. When changing the dressing, the spring clip can be loosened to change the dressing. After changing the dressing, it can be re-clamped on the abscess skin. For the first situation where drainage needs to be placed, the spring clip is clamped on the skin without the need to make another incision on the skin to suture and fix the drainage device, thereby reducing the patient's pain and the workload of medical staff.
