Multifunctional venous infusion apparatus

Abstract

The invention relates to a multifunctional venous infusion apparatus, which comprises a multi-bottle automatic connection portion, an automatic exhausting and defoaming portion and an automatic alarming portion, wherein a headstand-free and automatic infusion stopping portion is arranged between the multi-bottle automatic connection portion and the automatic exhausting and defoaming portion additionally; the headstand-free and automatic infusion stopping portion comprises an observation window and a second biswitch float valve; a cavity of the second biswitch float valve communicates with the observation window; an air filter core and a valve switch are arranged at an outlet at top end of the second biswitch float valve, and the outlet at lower end of the second biswitch float valve is connected with a flow regulator; a biswitch float body is installed in the cavity of the second biswitch float valve; the upper end and the lower end of the biswitch float body are provided with one sealing piece, respectively; an inlet of the observation window is connected with the outlet of the biswitch float valve in the multi-bottle automatic connection portion. Through the adoption of the multifunctional venous infusion apparatus, the operation of nursing staff to invert the observation window of the infusion apparatus is cancelled; the air and bubble are automatically removed; multiple bottles of medicinal liquids are automatically connected; and the medicinal liquid is stopped to alarm after infusion. Therefore, the workload of the nursing staff is alleviated, and the working quality and efficiency are improved.

Description

technical field [0001] The invention relates to a multifunctional intravenous infusion device, which can avoid the operation of the observation window of the infusion device for nursing staff, can also automatically exhaust and remove air bubbles, and can automatically dispense multiple bottles of liquid medicine continuously and automatically stop the liquid and give an alarm after infusion. Background technique [0002] At present, in the process of intravenous infusion of multiple bottles of medicinal liquid for patients, the hospital always replaces the next bottle after finishing one bottle and continues to infuse, and it is impossible to realize automatic continuous infusion of multiple bottles. Once there are many infusion patients, nurses are called by nursing staff or patients to run back and forth to change infusion bottles. The workload is very heavy and the labor intensity is very high. In addition, before the infusion, the nurse has to bend the hose of the infus...

Problems solved by technology

[0002] At present, in the process of intravenous infusion of multiple bottles of medicinal liquid for patients, the hospital always replaces the next bottle after finishing one bottle and continues to infuse. It is impossible to realize automatic continuous infusion of multiple bottles

Once there are many infusion patients, the nurses are called by the nurses or patients to run back and forth to change the infusion bottles. The workload is heavy and the labor intensity is very high.

In addition, before the infusion, the nurse has to bend the hose of the infusion set and stand the observation window upside down so that the liquid medicine is poured to a certain position of the observation window before erecting the observation window; before the infusion, a certain amount of liquid medicine needs to be released to remove the air, resulting in waste , the medicinal liquid is discharged to the ground, which also causes the ground to be wet, and it is easy to form a smooth surface on the tiles. Passers-by are more likely to fall, causing personal injury, and becoming an inducement for civil disputes, involving too much manpower in the hospital to handle disputes; Forming stains, affecting the appearance, is a breeding ground for bacteria and viruses, becoming a source of pollution, polluting the air, causing the possibility of cross-infection of patients, aggravating the condition, not conducive to the recovery of patients and affecting the health of nursing staff, and increasing the workload of sanitation and cleaning personnel ;The infusion set is easy to generate gas and liquid mixing inside the funnel, resulting in the formation of air bubbles in the catheter and adsorption in the tube wall. It is necessary to pinch the catheter, press the catheter with fingers or wrap the tube to remove the bubbles attached to the tube wall. The operation is cumbersome, time-consuming and labor-intensive. Nurses need to repeat the operation many times to get rid of the air bubbles, which greatly affects the nurses' work efficiency; The flow regulator cannot be closed in time after the liquid medicine is dispensed, resulting in the risk of blood return and even venous blood vessels entering the air, which invisibly increases the burden and psychological pressure on patients or their nursing staff, especially those who are seriously ill and unattended. Patients are more prone to accidents

[0003] Although the traditional floating body infusion set has the function of automatically stopping the liquid, once the liquid is automatically stopped, the tens of milliliters of liquid medicine below the floating body in the infusion set tube cannot continue to be injected into the human body, which will inevitably cause waste of liquid medicine
