Postoperative analgesia drug delivery device for solving drug delivery amount adjusting failure and insufficient drug delivery

Abstract

The invention relates to the technical field of medical equipment, and discloses a postoperative analgesia drug delivery device for solving drug delivery amount adjusting failure and insufficient drug delivery. The device comprises a liquid storage tank, wherein the liquid storage tank is used for storing liquid medicine, a conveying pipe is arranged on the outer side of the liquid storage tank, and the liquid medicine is transferred by the conveying pipe; through the cooperative use of a gas conveying cavity and a rotating shaft, the inner wall wrinkles of the drug delivery position are supported by air pressure during drug delivery, so that dead corners are avoided during drug delivery, and the drug delivery is more sufficient; through the cooperative use of a rotary button, a threaded rod, a first connecting rod, a second connecting rod, a rotary disc, a third connecting rod and a push rod, quantitative and uniform drug delivery is achieved during drug delivery, the drug delivery amount can be adjusted according to different treatment stages, and the intelligence of the device during use is improved; and through the cooperative use of a rack and a half gear, the two steps of air pressure generation and quantitative drug delivery are linked, so that the linkage of the whole device is improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a postoperative analgesic applicator that solves the problem that the dosage cannot be adjusted and the administration is insufficient. Background technique [0002] With the advancement and development of science and technology, my country's medical level is gradually improving, and there are differences in the treatment and administration of different departments. Among them, for obstetrics and gynecology, due to the need for uterine expansion during individual operations , dilatation, curettage, forceps and other operations, as well as the compression of the uterine wall by the expansion balloon, the postoperative pain caused to the patient is unbearable, and there is a relatively serious postoperative pain. Administer analgesia. At present, in the process of drug administration, due to the folds in the inner wall of the uterine cavity, it cannot be supported during t...

Problems solved by technology

At present, in the process of drug administration, due to the folds in the inner wall of the uterine cavity, it cannot be supported during the drug delivery process, resulting in dead angles during the drug delivery process, which may easily lead to insufficient drug delivery, thereby affecting analgesia Effect, increase the discomfort of the patient, and another convenience, the dosage cannot be adjusted when administering the drug, so it cannot be adjusted according to different recovery stages, and the function is relatively single

[0003] Aiming at the deficiencies of the prior art, the present invention provides a postoperative analgesic applicator that solves the problem of inability to adjust the dosage and insufficient administration, which has the advantages of adjusting the dosage and sufficient administration, and solves the existing The problem of relatively simple setting of the drug delivery device ensures that the inner wall can be supported by air pressure when using the device for operation, so that the drug delivery is more sufficient, and the sprayed amount can be changed during the drug delivery process, which is more effective. The intelligence and convenience of the device improve the intelligence of the device and make the operation easier
