Description
Technical Field
The utility model belongs to the technical field of medical instruments, and particularly relates to a liquid medicine supply pipeline device with a one-way valve.
Background
When medical liquid medicine nursing is supplied or anesthesia is supplied, often need to nurse the liquid medicine for the patient and supply or carry out the anesthesia medicine and supply, so that carry out nursing better or carry out operation on next step, nursing liquid medicine is supplied or carry out the anesthesia medicine and supply the liquid medicine that utilizes infusion injection small dose to supply or supply the human body with the anesthesia medicine mostly at present, in this kind of nursing liquid medicine supply or carry out the anesthesia liquid medicine supply mode, external liquid medicine supply pipe on the main transfer line lateral wall, because the infusion bottle often than higher, under the action of gravity, the infusion may flow backward in the liquid medicine supply pipe, cause the problem that the liquid medicine can't in time supply to patient's health inside. Particularly, when the pressurized infusion bag is used for rapid rescue medicine supply, the liquid medicine flows backward more obviously, which is very unfavorable for precise medicine supply for rescue. In order to overcome the problem that the liquid medicine cannot be timely input into the human body, improvement is needed according to the needs.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a liquid medicine supply pipeline device with a one-way valve, so as to improve the effect of supplying small-dose liquid medicine or anesthetic medicine in the infusion process and prevent liquid from flowing backwards in the infusion process. Is particularly suitable for avoiding the situation of back flow of the liquid medicine when a pressurized infusion bag is used for infusion.
In order to achieve the above object, the present invention has the following technical means.
The utility model provides a liquid medicine supply pipe device with check valve, includes infusion bag, main feed pipe, the transfer line, the liquid medicine feed pipe, micropump and liquid medicine syringe, main feed pipe upper end is connected with infusion bag lower extreme export, and main feed pipe lower extreme is connected with the transfer line, and main feed pipe lateral wall is connected with the liquid medicine feed pipe, and the liquid medicine feed pipe other end is connected on the export of liquid medicine syringe, and the liquid medicine syringe is laid on medical dedicated micropump, wherein, is provided with the check valve on the liquid medicine feed pipe.
Furthermore, the micro pump is a micro injection pump special for medical treatment, and the model number of the micro pump is SN-50T 66.
Furthermore, the infusion bag is a common infusion bag and is hung at a high position.
Furthermore, the infusion bag is a pressurized infusion bag, so that rapid pressurized liquid supply is facilitated.
The utility model discloses a beneficial effect lie in: the utility model discloses an among the device, utilize the check valve can play better contrary effect of hindering, the liquid medicine in the main feed pipe can not flow into in the liquid medicine feed pipe right side. Especially when infusion bag adopts pressurization infusion bag to realize supplying the liquid medicine fast, this check valve can play the effect that blocks liquid medicine adverse current to in the liquid medicine feed tube better, conveniently carries out the liquid medicine supply or carries out anesthesia medicine supply for the patient more accurately.
Drawings
FIG. 1 is a schematic diagram of the structure of the apparatus used in the example of the present invention.
The notation in the figure is: 1. an infusion bag; 2. a main liquid supply pipe; 3. a one-way valve; 4. a transfusion tube; 5. a liquid medicine supply tube; 6. a micro pump; 7. a liquid medicine injector.
Detailed Description
The following description of specific embodiments of the present invention is provided in order to better understand the present invention with reference to the accompanying drawings.
As shown in fig. 1, the liquid medicine supply or anesthetic drug supply pipe device with a check valve comprises an infusion bag 1, a main liquid supply pipe 2, an infusion tube 4, a liquid medicine supply pipe 5, a micro-pump 6 and a liquid medicine injector 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 tube 4, the side wall of the main liquid supply pipe 2 is connected with the liquid medicine supply pipe 5, the other end of the liquid medicine supply pipe 5 is connected with the outlet of the liquid medicine injector 7, the liquid medicine injector 7 is arranged on the micro-pump 6 special for medical treatment, and the check valve 3 is arranged on the liquid medicine supply pipe 5. The micro pump 6 is a micro syringe pump special for medical treatment, and is SN-50T 66.
When the infusion bag is used, the liquid medicine in the infusion bag 1 is supplied to the infusion tube 4 from the main liquid supply tube 2, is supplied to a patient under the action of gravity, after small-dose liquid medicine which needs to be injected to the patient is supplied or anesthetic is prepared, the infusion bag is placed in the liquid medicine injector 7, the liquid medicine injector 7 is connected with the liquid medicine supply tube 5, the liquid medicine is slowly pushed to the liquid medicine supply tube 5 from the liquid medicine injector 7 under the action of a pump by using a micro pump 6 special for medical treatment, the liquid medicine is supplied to the main liquid supply tube 2 through the check valve 3, and the liquid medicine is mixed with the liquid medicine in the main liquid supply tube 2 and flows into the infusion tube 4 to be supplied to a human body, so that the liquid medicine supply or the anesthetic effect is achieved. Since the check valve 3 has a check effect, the medical liquid in the main liquid supply tube 2 does not flow into the right side of the medical liquid supply tube 5. Especially, when the infusion bag 1 adopts a pressurized infusion bag to realize rapid liquid medicine supply, the one-way valve 3 can better play a role in blocking the liquid medicine from flowing back to the liquid medicine supply pipe 5.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the utility model.
