technical field

The utility model relates to daily necessities for human beings, in particular to medical equipment, in particular to a negative pressure drainage ball for preventing infection.

Background technique

Negative pressure drainage technology is applied to the drainage of many surgical wounds after surgery. The clinically used disposable negative pressure drainage ball: the drainage tube is placed in the body, and the open wound is closed by using a biological semipermeable membrane, and then produced by squeezing the ball outside the body. With a certain negative pressure, blood and exudate from the postoperative wound flow into the external sphere through the drainage tube. This technology can accelerate the blood circulation of the wound to a certain extent, smooth drainage, reduce edema, promote wound healing, and create favorable conditions for postoperative rehabilitation. However, the existing negative pressure drainage ball has many inconveniences in the daily clinical nursing process (such as the need to carry a hemostat to block the drainage when measuring, clean the outlet of the drainage fluid, and cannot conveniently observe the value of the exposed length of the drainage tube, etc.), especially Lack of devices to prevent retrograde drainage fluid, easy to cause drainage fluid retrograde infection of patients.

Further, a connecting ring is also arranged on the connecting piece.

Further, the outer wall of the drainage tube is provided with a first scale along the axial direction.

Further, the surface of the sphere is provided with a second scale along the up and down direction.

Further, the stop clip includes a flat rectangular clamping plate, a flow hole and a stop groove are arranged on the clamp plate, one end of the stop groove and the flow hole connected.

Working principle: The wound of the patient is isolated from the outside air and drainage fluid during the entire drainage process through the structure of the stop clip, the ventilation valve and the drainage tube, so that infection is not easy to occur.

Compared with the prior art, the beneficial effects of the utility model are: 1. Maintain the isolation state between the abdomen and the outside world during the maintenance of the drainage tube, and prevent the occurrence of intra-abdominal infection by preventing the backflow of the drainage fluid; 2. There is a scale on the drainage tube, It is convenient for medical staff to observe and record the length of the outer section of the drainage tube, to detect changes in the position of the drainage tube in time, and to prevent the risk of unplanned extubation; 3. The scale on the drainage ball is convenient for recording the volume of drainage fluid; 4. The connecting ring is convenient for the patient to carry the drainage ball after action .

Detailed ways

Example 1

Please refer to Fig. 1 and Fig. 2, the utility model provides a technical solution:

An anti-infection negative pressure drainage ball, comprising a transparent hollow sphere 1, the lower end of the sphere 1 communicates with a drain tube 2, a one-way valve 201 is arranged in the cavity of the drain tube 2, and the one-way valve 201 The flow direction is from the sphere 1 to the outside, and a discharge switch 202 is also arranged on the discharge pipe 2; a connecting piece 3 is arranged on the upper end of the sphere 1, and a vent valve 4 is arranged on the connecting piece 3, and the vent valve 4 passes through The connecting piece 3 is in communication with the inner cavity of the sphere 1, a ventilation switch is arranged on the ventilation valve 4, a filter membrane 401 is arranged inside the ventilation valve 4, a drainage tube 5 is also arranged on the connecting piece 3, and the drainage tube 5 passes through Pass through the connecting piece 3 and communicate with the inner cavity of the sphere 1 , and an end of the drainage tube 5 close to the connecting piece 3 is provided with a stop clip 6 .

Further, a connecting ring 7 is also provided on the connecting piece 3 .

Specifically, the connecting ring 7 is convenient for the patient to hang the device on the clothes, which is convenient for the patient to get out of bed and walk without using pins and other methods to prevent puncture injuries.

Further, a first scale 501 is provided on the outer wall of the drainage tube 5 along the axial direction.

Specifically, the first scale 501 is convenient for marking the length of the drainage tube 5 outside the patient's body, and it is convenient for the medical staff to find in time that the drainage tube 5 is introduced into or discharged from the patient's body due to the patient's turning or other large movements, resulting in a medical emergency. ACCIDENT.

Further, the surface of the sphere 1 is provided with a second scale 101 along the up and down direction.

Specifically, it is convenient for medical staff to register the volume of fluid drained each time.
