Technical Field

[0001] The utility model relates to the technical field of medical infusion devices, and particularly relates to an infusion set connection device convenient for replacing drug administration. Background Art

[0002] An infusion set is an infusion instrument for establishing a passage between blood and a vein. At present, when medical staff perform blood transfusion operations on patients, a blood bag is directly connected to an indwelling needle on the patient through an infusion set. If a patient has a blood transfusion reaction and needs to be administered drugs in a timely manner, currently, only the infusion set connecting the blood bag can be directly pulled out from the indwelling needle, and then drugs are delivered into the patient's body through the indwelling needle. After the blood bag and the infusion set are taken out, due to external contamination factors, the blood bag cannot be used continuously, resulting in a great waste of medical products.

[0024] When medical staff perform blood transfusion operations on patients, the blood bag is directly connected to the indwelling needle on the patient through an infusion set. If a patient has a blood transfusion reaction and drugs need to be delivered to the patient in a timely manner, currently, only the infusion set connected to the blood bag can be directly pulled out from the indwelling needle, and then drugs are delivered into the patient's body through the indwelling needle. After the blood bag and the infusion set are taken out, due to external contamination factors, the blood bag cannot be used continuously, causing great waste of medical products. To address the above problems, the present utility model provides an infusion set connection device that facilitates the replacement of drug administration. By setting a multi-way valve for connection, during normal blood transfusion, the blood bag and the infusion set are connected to the indwelling needle on the patient through the multi-way valve. When drugs need to be delivered into the patient's body midway, the drugs can be input into the human body through the multi-way valve, avoiding interference with the original infusion set and having the advantage of high flexibility in use. The specific solution is as follows.

[0025] Referring to Figure 1 and Figure 2 As shown, an infusion set connection device that facilitates the replacement of drug administration according to the present utility model includes a valve body 1 and a tubing winder 2. Among them, the valve body 1 has at least three connection ports 11, one of which is for connecting the indwelling needle tube and one is for connecting the infusion set. The valve body 1 is fixedly arranged on the outside of the tubing winder 2. The tubing winder 2 includes a shaft body 21 for winding and storing the tubing and a limiting component for restricting the tubing from disengaging from both ends of the shaft body 21.

[0026] Exemplarily, when using this device, the valve body 1 is mainly used to realize the connection between the indwelling needle tube and the infusion set. During normal blood transfusion, the blood bag is sequentially connected to the indwelling needle tube through the infusion set and the valve body 1 to achieve normal blood transfusion. When a patient has a blood transfusion reaction, medical staff need to quickly inject other drugs into the patient. At this time, the medical staff do not need to remove the infusion set connected to the blood bag. Only by manipulating the valve body 1 to disconnect the connection state between the infusion set and the indwelling needle tube, and then connecting the injection device with the drug to another connection port 11 of the valve body 1 and manipulating the valve body 1 to connect the injection device and the indwelling needle tube, drug injection can be carried out at this time. During the operation process, there is no need to remove the infusion set anymore. By using this device, during normal blood transfusion, the blood bag and the infusion set are connected to the indwelling needle on the patient through a multi-way valve. When drugs need to be delivered into the patient's body midway, the drugs can be input into the human body through the multi-way valve, avoiding interference with the original infusion set, and having the advantage of high use flexibility.

[0027] Specifically, in this embodiment, the valve body 1 specifically includes a three-way valve. By manipulating the valve rod 12 on the three-way valve, the connection state of each connection port 11 can be controlled.

[0028] In addition, the setting of the tubing winder 2 can also facilitate medical staff to organize the tubing of the infusion set. During the preparatory stage of nursing supplies, after the medical staff complete the item allocation, the infusion set can be wound and stored on the tubing winder 2 for item organization.

[0029] In an embodiment, the overall structure of the limiting component is further refined. The limiting component includes two limiting pieces 22, and the two limiting pieces 22 are fixedly arranged at both ends of the shaft body 21.

[0030] Specifically, an avoidance hole 23 for the tubing to pass through is provided on the limiting piece 22 close to the valve body 1.

[0031] Exemplarily, after the medical staff complete the item allocation, the tubing of the infusion set is wound and stored on the tubing winder 2, and the interface of the infusion set can pass through the avoidance hole 23 on the limiting piece 22 and be connected to the valve body 1. The setting of the avoidance hole 23 facilitates the connection between the infusion set and the valve body 1.

[0032] In this embodiment, more preferably, the limiting pieces 22 are both provided with a hollow structure. The hollow structure can simplify the device, reduce the manufacturing cost, and the hollow part can also replace the avoidance hole 23 to achieve the effect of optimizing the structural layout of the device.

[0033] In this embodiment, specifically, a positioning groove 24 for the pipeline to be clamped is provided on the shaft body 21. The groove width of the positioning groove 24 corresponds to the pipeline. During the winding and storage operation of the infusion set, first complete the connection of its interface and valve, and then press the adjacent pipeline into the positioning groove 24 to position and fix this part. Subsequently, the winding of the remaining pipelines of the infusion set can be continued. The positioning groove 24 can position this part of the pipeline while maintaining the connectivity of the pipeline, so as to facilitate subsequent winding operations.

[0034] More preferably, in order to further position the pipeline wound on the pipe winder 2, a metal strip 25 is provided on the limiting piece 22. The metal strip 25 is used to bend and restrain the pipeline wound on the shaft body 21. Among them, the metal strip 25 is a soft metal so that it can be easily bent.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
