Embodiment 1

[0026] Embodiment 1, the power device 3 is an electric power device, including a motor, a reducer and a timing control device, the power output end of the motor is connected to the reducer, and the reducer is meshed with the transmission gear 4 through gears, and between the reducer and the transmission gear 4 There is a timing control device between them, and the timing control device is provided with a locking piece, which can control the speed between the reducer and the transmission gear 4, and a locking piece is installed on the transmission shaft between the reducer and the transmission gear 4. The design is to realize the rotation of the drainage tube body 1 through electric transmission, and the electric rotation is stable and easy to operate, and the timing control device can ensure the constant rotation of the drainage tube body 1 .

Embodiment 2

[0027] In embodiment 2, such as image 3 As shown in , the power device 3 is a mechanical power device, including a barrel assembly 31, a span wheel 32 engaged with the barrel assembly 31, a vertical wheel 33 engaged with the span wheel 32, and a handle fixed to the vertical wheel 33 The shaft 34 is provided with a locking piece on the tangent surface of the stem 34. The locking piece is embedded in the stem 34 to avoid the rebound of the stem 34. The material of the locking piece can be plastic or metal. By rotating the stem 34, Tighten the mainspring 314 in the barrel assembly 31, this design realizes the rotation of the drainage tube body 1 through mechanical power, the structure is simple, the operation is convenient, and the price is cheaper.

[0028]Among the above, the barrel assembly 31 includes a barrel shaft 311, a barrel box 312, a barrel cover 313, a clockwork spring 314, a clockwork spring outer hook 315 and a barrel wheel 316. Both are fixedly welded and connect...

Abstract

The invention discloses a closed type negative-pressure drainage tube. The closed type negative-pressure drainage tube comprises a drainage tube body, which is composed of a hollow front end, a hollow rear end, and a shaft unit connecting the front end and the rear end; wherein the shaft unit is movably provided with a fixing unit in a sleeving mode; the rear end of the drainage tube body is connected with a power device, and the drainage tube body can rotate axially. The closed type negative-pressure drainage tube is simple in structure and convenient to use; the fixing unit is sutured onto human skin, the drainage tube body is powered by the power device to rotate slowly, so that drainage blind areas can be avoided, thorough drainage can be ensured, and blocking of the drainage tube body caused by tissues or muscles can be avoided; during treatment, the closed type negative-pressure drainage tube does not require frequent replacement and accordingly avoids secondary injury to patients.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a negative pressure drainage tube. Background technique [0002] Closed drainage (chest cavity, abdominal cavity, perianal local abscess cavity and other cavities) is a relatively common surgical operation. It is generally used to treat various lacunar hydrops, effusions, hemorrhages, empyema and pneumothorax. When in use, a negative pressure suction device is used to generate a certain negative pressure, and the drainage tube acts on the cavity of the lesion to attract various liquids and gases in the cavity, thereby facilitating the healing of the lesion. Current research proves that this therapy can accelerate the blood circulation in the cavity, significantly promote the entry of new blood vessels, stimulate the growth of granulation tissue, fully drain, reduce edema, reduce pollution, inhibit bacterial growth, and can directly accelerate wound healing, or for surg...
