Self-adaptive medicine supply mechanism for nursing medicine spraying device

Abstract

The invention relates to the technical field of medical nursing instruments, in particular to a self-adaptive medicine supply mechanism for a nursing medicine spraying device. The self-adaptive medicine supply mechanism comprises an outer barrel, an exhaust pipe, a medicine discharging pipe and a spherical sleeve, the lower end of the outer barrel is fixedly connected with a spherical block, a concave cavity is formed below the spherical block, the spherical sleeve is connected to the spherical block in a sleeving mode, the lower portion of the spherical sleeve is fixedly connected with a connecting barrel, a medicine barrel is connected on the lower partion of the connecting barrel in a threaded manner, a medicine suction head is fixedly connected to the inner bottom wall of the medicine barrel, the medicine suction head is fixedly connected with a hard medicine suction pipe, the medicine discharging pipe and the exhaust pipe pass through the connecting rod and the spherical block, a medicine discharging corrugated pipe and an exhaust corrugated pipe are fixedly connected in the concave cavity respectively, a hard medicine discharge pipe and a hard exhaust pipe are fixedly connected below the medicine discharge corrugated pipe and the exhaust corrugated pipe respectively, and the lower end of the hard medicine discharge pipe is in threaded connection with the hard medicine suction pipe. The self-adaptive medicine supply mechanism is reasonable in structural design, when the medicine spraying angle is properly adjusted according to the actual situation, the medicine cylinder is always kept vertical under the gravity action of the balancing weight, it is guaranteed that medicine liquid can be sucked all the time, operation is convenient, the medicine spraying device is suitable for various medical clinical medicine spraying devices, and the application prospect is wide.

Description

[0001] This application is a divisional application of an invention patent application with the application number 2018115657480, the invention name is a spraying device for ENT clinical care, and the application date is December 21, 2018. technical field [0002] The invention relates to the technical field of medical nursing devices, in particular to an adaptive drug supply mechanism for a nursing spray device. Background technique [0003] At present, doctors often need to use spraying devices for daily nursing and treatment of ENT patients. Traditional spraying devices are mostly integrated, relying on pushing or squeezing to discharge the medicine into the patient's ear canal, nasal cavity or In the throat, but the push method not only needs to be pushed back, it is inconvenient to use, but also there will be insufficient pressure. At the same time, because the doctor needs to adjust the use angle when using it, the liquid medicine will not be sucked out when the liquid ...

Problems solved by technology

But the device needs to be pre-programmed, and the weight ball alone is not enough to ensure that the hose can always absorb the medicine liquid in the medicine bottle
