Transfusion device having automatic bottle change and safety protection functions

Abstract

The invention relates to a transfusion device having automatic bottle change and safety protection functions. The structure of the transfusion device is that a first transfusion bottle gas passage is communicated with a gas inlet, a second transfusion bottle gas passage is communicated with an air space above a liquid stop film in a protection chamber, the air spaces above the liquid stop films in the two protection chambers are not communicated with each other, the protection chambers are integrally sealed, the air space is formed above the liquid stop film, a baffle is fixedly connected below the liquid stop film, a liquid leaking hole is formed in the baffle, a floating block is arranged below the baffle, an outlet is formed in the middle of the bottom of the protection chamber, the outlet is communicated with a transfusion pipe, and each transfusion bottle liquid passage is communicated to the position below the liquid stop film and above the baffle in the protection chamber. According to the invention, the protection chambers are utilized to enable multiple transfusion bottles to transfuse continuously and close the transfusion pipe after transfusion is completed, so as to prevent vein blood backflow, thereby greatly improving the transfusion safety and reducing the workload of medical care personnel.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to an infusion device with automatic bottle changing and safety protection. Background technique [0002] Before the present invention, in the current clinical process of intravenous infusion of multiple bottles of medicinal liquid to patients in hospitals, medical staff are required to manually change to the next bottle after filling one bottle, and the automatic continuous filling function cannot be realized. Once the number of infusion patients is large, medical staff need to keep running around to change the bottle, which greatly increases the workload of medical staff. In addition, the patient himself and his escorts also need to constantly observe the infusion bottle. They are worried that if the bottle is not replaced in time after the infusion is completed, the venous blood will return to the vein or even the air will enter the vein, which will pose a serious threat to the pat...

Problems solved by technology

[0002] Before the present invention, at present, in the process of intravenous infusion of multiple bottles of medicinal liquid to patients in clinical hospitals, it is necessary for medical staff to manually switch to the next bottle after one bottle is finished, and the automatic continuous injection function cannot be realized.

Once the number of infusion patients is large, medical staff need to run around to change bottles, which greatly increases the workload of medical staff

In addition, the patients themselves and their accompanying staff also need to keep observing the infusion bottle, worrying that if the bottle is not changed in time after the infusion is completed, the venous blood will return or the vein will enter the air, which will pose a serious threat to the patient's health and cause huge mental pressure to the patient.
