Disc type control dropper of multifunctional adaptive continuous infusion set

Abstract

The invention discloses a disc type control dropper of a multifunctional adaptive continuous infusion set. The disc type control dropper comprises a controller (4) and a dropper body (5), and is characterized in that the controller (4) comprises a protective cover (41), a motor (42), a central control unit (43), a flow sensor (44), an infrared position sensor (45), a transmission shaft (47), a valve plate (48), a valve plate infusion channel (481), a valve plate long conduit air filter passage (482), and a bearing (49). The disc type control dropper has the advantages of simple structure, highoperability and high reliability, and the core component, namely the control dropper body can be repeatedly used, which greatly reduces the use cost.

Description

technical field [0001] The invention relates to the medical field, in particular to a disc-type regulating dropper of a multifunctional self-adapting continuous infusion set. technical background [0002] Infusion sets are commonly used medical devices for clinical intravenous injection, such as figure 1 As shown, the infusion set is generally composed of a bottle stopper puncturer protective cover, a bottle stopper puncturer, an air filter, a water stop clip, a Mufei dropper, a long infusion catheter, a flow adjustment device, a liquid medicine filter, and an outlet conical joint. . The upper end of the infusion set is connected with the infusion bottle, and the lower end is matched with the intravenous infusion needle, and the whole infusion process is completed under the action of gravity. In the actual clinical intravenous infusion process, the infusion set usually has only one infusion channel, but continuous infusion of multiple infusion bottles is often required. Du...

AI Technical Summary

Problems solved by technology

The method of exhausting is to place the Mufei dropper horizontally, and when there is enough liquid in the dropper, squeeze the dropper with your fingers, so that the medicinal liquid can quickly enter the long infusion catheter, and the air is exhausted through the intravenous infusion needle. very time consuming process

During this process, once the squeezing action is a little careless, a large number of small air bubbles will be attached to the inner wall of the long infusion tube on the lower side of the infusion set's Murphy's dropper. In order to discharge these air bubbles, the medical staff need to flick them with their fingers The wall of the infusion set, very troublesome and not very effective

In addition, the method of expelling air from the outside of the infusion set by squeezing the wall of the infusion tube may also cause damage to the infusion catheter, and the damaged infusion catheter will affect the infusion performance of the infusion set, thereby reducing the reliability of the infusion set;

[0004] Second, in the process of continuous infusion of multiple bottles of infusion bottles, it is necessary to manually replace the infusion bottles

When changing the infusion bottle, if the liquid level of the remaining drug solution in the infusion set is lower than the lower part of the Murphy dropper, it is necessary to re-exhaust or restart the intravenous injection: when the liquid level is only a short distance lower than the dropper, the doctor and nurse The personnel usually wrap the infusion tube around the finger from bottom to top to squeeze out the air gradually; when the liquid level is lower than the dropper, the medical staff need to open the conical joint and discharge the air from the end of the long infusion tube. The process will inevitably lead to waste of liquid medicine, and at the same time, it is easy to cause interface infection

Since medical staff often need to take care of patients in multiple wards at the same time, it takes a lot of time and energy to frequently replace infusion bottles. On the one hand, it is easy to cause physical and mental fatigue of medical staff, and on the other hand, errors may occur during the tedious replacement process ( For example, the infusion was not replaced in the correct order), resulting in a greatly reduced infusion effect, and even medical accidents;

[0005] Third, the current clinical intravenous infusion cannot automatically stop the infusion

At the end of the infusion, if the medical staff does not take care in time and the liquid level drops too low, it will cause blood back phenomenon, and in severe cases, gas will enter the human body, causing adverse consequences such as gas embolism

In order to prevent the liquid level from being too low, medical staff, patients and family members need to take care in real time, causing unnecessary tension and psychological burden on the three;

[0006] Fourth, for blood transfusion or precious liquid medicine, medical staff need to manually confirm before transfusion and clean up after transfusion

Confirmation before delivery and cleaning after delivery require professionals to complete, which is very inconvenient

[0007] Fifth, the current clinical intravenous infusion cannot automatically adjust the infusion speed

[0010] Second, the method of using the different hanging heights of infusion bottles to generate pressure differences will, on the one hand, place great demands on the infusion space; It will cause difficulty for the nursing staff to hang the infusion bottle;

[0011] Thirdly, multiple buoyancy valves have different pressures due to different suspension heights of the buoyancy valves, which also makes it difficult for the infusion space and the nurses to hang the infusion bottle;

[0012] Fourth, the buoyancy valve is used as a one-way control or a way to control the pressure difference generated by different infusion tubes. Due to its complex structure, it is affected by the arrangement of the infusion set and the arrangement of the infusion bottle, and there is a problem of reliability. Reliability is important for the infusion set. It is very important that if the continuous infusion of the infusion bottle does not enter the infusion set in time, there will be a period of air in the middle, which will cause a major accident
