Description

An adjustable negative pressure drain

technical field

The utility model relates to the technical field of medical devices, in particular to an adjustable negative pressure drain.

Background technique

At present, many patients' wounds will have effusion after surgery. If it is not removed in time, it will not only increase the pain of the patient, but also be unfavorable for the recovery of the wound, and even easily lead to infection and secondary abscess. For patients after a variety of operations, negative pressure drainage is often used to guide the post-operative cavity effusion or wound exudate to the outside of the body to prevent postoperative infection and affect wound healing. During the drainage process, the effusion needs to be continuous and effective. It is necessary to prevent the backflow of drainage fluid and cause infection, so negative pressure drainage devices are widely used.

However, in the existing negative pressure drainage equipment, the drain outlet is generally located at the upper end of the casing, which is inconvenient to deal with the accumulated fluid; the drainage fluid is difficult to measure accurately; in addition, the used drain device cannot adjust the negative pressure according to the needs; and some large-scale The drainage device has a complex structure, high cost, and is not easy to move. A little careless operation can cause infection, and it is not easy to operate, which brings a lot of inconvenience to medical staff.

Chinese Patent Application: CN102107027A discloses a negative pressure drain, comprising an indwelling needle and a syringe, the indwelling needle and the syringe are connected by an extension tube, and the outer circumference of the needle core of the indwelling needle head is sleeved with a cannula tightly connected with it. The device can continuously drain, reduce the amount of exudate, and be less prone to infection, thereby reducing patient pain and physician workload. However, the device uses a syringe to achieve drainage. The human-driven negative pressure has a short duration, unstable pressure, and poor reliability. Since the negative pressure chamber and the liquid storage chamber use the same container, it cannot be used continuously and cross infection is prone to occur.

Chinese patent application: CN206792716U discloses a negative pressure drainage device, which includes a drainage ball, a drainage tube and an automatic liquid suction tube. A drainage port and a liquid suction port are arranged above the drainage ball, and one end of the drainage tube is provided with a drainage connection part. , and is sealedly connected with the drainage port through the drainage connection part, and the other end is connected with the part of the human body that needs drainage. The liquid suction port is arranged inside the drainage ball, and the liquid suction port is tightly connected with the outer wall of the liquid suction pipe or the liquid suction connection part. This device mainly solves the problem of inaccurate calculation of the amount of drainage, which is prone to reverse flow. However, the liquid outlet of the device is located at the upper end, which is inconvenient to deal with the accumulated liquid, and the device is not equipped with a pressure regulator and a pressure measurement device. In the actual operation process, it is not possible to adjust the appropriate negative pressure according to the needs, which is not conducive to popularization and use.

Therefore, to sum up, there is an urgent need for an adjustable negative pressure drainage device that can easily handle the effusion, facilitate accurate measurement, and can adjust the negative pressure and prevent the backflow of the drainage fluid. , has not yet been reported.
