Description

A liquid medicine supply pipeline device with one-way valve

technical field

The utility model belongs to the technical field of medical appliances, in particular to a medicinal liquid supply pipeline device with a one-way valve.

Background technique

When supplying medical liquid nursing or anesthesia, it is often necessary to supply nursing liquid or anesthetics to patients in order to better carry out nursing or perform the next operation. Currently, nursing liquids or anesthetics are supplied. Most of them use infusion to inject a small dose of liquid medicine or supply anesthetics to the human body. In this nursing liquid supply or anesthetic liquid supply mode, the main infusion pipe is connected to the side wall of the external medicine supply pipe. It is often relatively high. Under the action of gravity, the infusion may be poured back into the liquid medicine supply pipe, resulting in the problem that the liquid medicine cannot be supplied to the patient's body in time. In particular, when a pressurized infusion bag is used to implement rapid rescue medicine supply, the backflow of the medicine solution is more obvious, which is very unfavorable for accurate rescue medicine supply. In this regard, it needs to be improved according to the needs in order to overcome the problem that the medicinal liquid cannot be input into the human body in time.

Utility model content

The purpose of the utility model is to provide a medicinal liquid supply pipeline device with a one-way valve, so as to improve the supply of small doses of medicinal liquid during the infusion process or carry out the effect of anesthetic drug supply, and prevent the liquid from being poured back during the infusion process. It is especially suitable for the use of pressurized infusion bag infusion to avoid the situation of liquid infusion.

In order to achieve the above objects, the technical solutions of the present invention are as follows.

A liquid medicine supply pipeline device with a one-way valve, comprising an infusion bag, a main liquid supply pipe, an infusion pipe, a liquid medicine supply pipe, a micro pump and a liquid medicine syringe, and the upper end of the main liquid supply pipe is in phase with the outlet of the lower end of the infusion bag. Connection, the lower end of the main liquid supply pipe is connected with the infusion pipe, the side wall of the main liquid supply pipe is connected with the liquid medicine supply pipe, the other end of the liquid medicine supply pipe is connected to the outlet of the liquid medicine syringe, and the liquid medicine syringe is placed in a special medical solution. On the micro pump, wherein, a one-way valve is arranged on the liquid medicine supply pipe.

Further, the micro-pump is a medical-specific micro-injection pump, and its model is SN-50T66.

Further, the infusion bag is an ordinary infusion bag, which is hung at a high place.

Further, the infusion bag is a pressurized infusion bag, which is convenient for fast pressurized liquid supply.

The beneficial effect of the utility model is that in the device of the utility model, the use of the one-way valve can play a better anti-reverse effect, and the medicinal liquid in the main liquid supply pipe will not flow into the right side of the medicinal liquid supply pipe. Especially when the infusion bag adopts a pressurized infusion bag to achieve rapid supply of liquid medicine, this one-way valve can better prevent the reverse flow of liquid medicine into the liquid medicine supply pipe, which is convenient and accurate for patients. Liquid medicine supply or anesthesia supply.

Detailed ways

The specific embodiments of the present utility model will be described below in conjunction with the accompanying drawings for better understanding of the present utility model.

As shown in Figure 1, the pipeline device for supplying medicinal solution with one-way valve or supplying anesthetics includes an infusion bag 1, a main liquid supply pipe 2, an infusion pipe 4, a medicinal liquid supply pipe 5, a micro pump 6 and a medicine liquid supply pipe 5. Liquid syringe 7, wherein the upper end of the main liquid supply pipe 2 is connected with the outlet of the lower end of the infusion bag 1, the lower end of the main liquid supply pipe 2 is connected with the infusion pipe 4, and the side wall of the main liquid supply pipe 2 is connected with the medicinal liquid supply pipe 5. The other end of the liquid medicine supply pipe 5 is connected to the outlet of the liquid medicine syringe 7, the liquid medicine syringe 7 is placed on the micro pump 6 dedicated to medical treatment, and the one-way valve 3 is arranged on the liquid medicine supply pipe 5. The micro-pump 6 is a medical-specific micro-injection pump, and its model is SN-50T66.

When in use, the liquid medicine in the infusion bag 1 is supplied from the main liquid supply pipe 2 to the infusion pipe 4, and is supplied to the patient under the action of gravity. Placed on the liquid medicine syringe 7, the liquid medicine syringe 7 is connected to the liquid medicine liquid supply pipe 5, and the medical liquid is slowly pushed from the liquid medicine liquid syringe 7 to the liquid medicine liquid supply pipe 5 under the action of the micro pump 6 dedicated for medical treatment. In the middle, it is supplied to the main liquid supply pipe 2 after passing through the check valve 3, mixed with the medical liquid in the main liquid supply pipe 2, and then flows into the infusion pipe 4, and is supplied to the human body to provide medical liquid supply or anesthesia effect. Since the check valve 3 has a reversal effect, the chemical liquid in the main liquid supply pipe 2 will not flow into the right side of the chemical liquid supply pipe 5 . Especially when the infusion bag 1 adopts a pressurized infusion bag to realize the rapid supply of the liquid medicine, the one-way valve 3 can better prevent the reverse flow of the liquid medicine into the liquid medicine supply pipe 5 .

The above are the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the principles of the present invention, several improvements and modifications can be made. These improvements and modifications It is also regarded as the protection scope of the present invention.
