Description

Technical Field

[0001] The utility model belongs to the technical field of medical infusion sets, and particularly relates to a colloidal liquid infusion set with a cleaning function. Background Art

[0002] Tube flushing is a medical procedure. When treating tumors or during radiotherapy, it is necessary to deliver colloidal liquids such as hemoglobin. After the delivery is completed, it is usually necessary to use normal saline to clean the residual medicinal liquid originally attached to the infusion tube. If tube flushing is not performed, during the cross-infusion of two groups of medicinal liquids, crystal particles or floccules will form in the Murphy's dropper. If the medicinal liquid with floccules enters the patient's body and enters microvessels such as the heart and brain microvessels along with blood circulation, embolism may occur, and the patient will experience symptoms such as palpitation, dizziness, and blurred vision. The existing tube flushing methods can only perform tube flushing on the infusion tube alone during tube flushing, and when flushing and cleaning the residual medicinal liquid in the infusion bottle, it is often necessary to disassemble it for separate cleaning. Content of the Utility Model

[0003] Aiming at the above defects, the utility model discloses a colloidal liquid infusion set with a cleaning function, mainly solving the problem that the existing technology needs to disassemble the infusion set for cleaning when flushing the infusion tube and the infusion bottle.

[0004] To achieve the above object, the utility model discloses a colloidal liquid infusion set with a cleaning function, including an infusion bottle and an infusion tube. The infusion tube is connected to the infusion bottle by inserting it into the bottle mouth of the infusion bottle. It further includes a flushing assembly with the function of flushing the infusion bottle and the infusion tube. The flushing assembly includes a syringe for containing a cleaning reagent and a three-way pipe for delivering the cleaning reagent to the infusion bottle and the infusion tube.

[0005] Beneficial Effects: The flushing assembly in this solution includes a syringe and a three-way pipe. The syringe can contain a cleaning reagent, and the three-way pipe can deliver the cleaning reagent to the infusion bottle and the infusion tube. Therefore, it not only has the function of cleaning the infusion tube but also can clean the infusion bottle.

[0006] Preferably, the three-way pipe includes a rubber tube connected to the syringe, a connecting pipe connected to the infusion tube, and a side tube connected to the infusion bottle. The connecting pipe is connected to the infusion tube near the bottle mouth of the infusion bottle, and the side tube is inserted into the bottle mouth of the infusion bottle to the bottom inside the infusion bottle.

[0007] Beneficial effects: The three-way pipe of this solution mainly consists of a rubber tube, a connecting pipe, and a side pipe. The rubber tube is connected to the syringe needle and serves to transport the cleaning reagent; the connecting pipe is responsible for transporting the cleaning reagent into the infusion tube; and the side pipe is responsible for transporting the cleaning reagent into the infusion bottle. The connecting pipe is connected to the infusion tube near the bottle mouth, so that the cleaning reagent can effectively clean the entire infusion tube, and the side pipe extends into the bottle to its bottom. Firstly, this can directly clean the bottom of the bottle. Secondly, since the infusion bottle is placed upside down during infusion, the side pipe is long enough to avoid the phenomenon that the accumulated cleaning reagent submerges the nozzle of the side pipe and causes backflow during the cleaning of the infusion bottle.

[0008] Preferably, liquid control valves for controlling the flow direction of the cleaning reagent are provided on the connecting pipe, the side pipe, and the infusion tube near the bottle mouth of the infusion bottle.

[0009] Beneficial effects: The liquid control valves are provided on three different pipes, so that the infusion bottle and the infusion tube can be cleaned separately. If it is necessary to clean the infusion bottle, open the liquid control valve on the side pipe and close the liquid control valves on the connecting pipe and the infusion tube, then the cleaning of the infusion bottle can be achieved alone; if it is necessary to clean the infusion tube, close the liquid control valve on the side pipe and open the liquid control valves on the connecting pipe and the infusion tube, then the cleaning of the infusion tube can be achieved alone.

[0010] Preferably, the number of the liquid control valves is at least three.

[0011] Beneficial effects: The number of the liquid control valves in this solution is at least three. On the one hand, it ensures that the infusion device can flush and clean the infusion tube and the infusion bottle separately. On the other hand, multiple liquid control valves can prevent the phenomenon that a certain control valve fails and the infusion device cannot normally perform the flushing and cleaning work.

[0012] Preferably, the syringe needle and the rubber tube are detachably connected, and a piston is further provided in the syringe needle, and the piston is used to push the cleaning reagent in the syringe needle.

[0013] Beneficial effects: The syringe needle and the rubber tube in this solution are detachably connected, which is convenient for replenishing the cleaning reagent. After the cleaning reagent is used up, the syringe needle is disassembled and refilled with the cleaning reagent, and then connected to the rubber tube after being filled. The piston in the syringe needle facilitates the user to push the cleaning reagent.

[0014] Preferably, a puncture needle for puncturing the bottle mouth of the infusion bottle is provided at the end of the side pipe.

[0015] Beneficial effects: The puncture needle provided at the end of the side pipe in this solution can effectively perform the bottle-puncturing operation and help the side pipe enter the infusion bottle more conveniently.

[0016] Preferably, the liquid control valve is a flow regulator.

[0017] Beneficial effects: The liquid control valve in this solution is set as a flow regulator, which not only has the function of controlling the flow direction of the cleaning reagent, but also can control the flow rate of the cleaning reagent by sliding the adjustment wheel on the flow regulator.

[0027] Embodiment 1

[0028] As an embodiment of the present utility model:

[0029] refer to Figures 1 to 3 In this embodiment, a colloidal liquid infusion device with a cleaning function mainly includes three parts, an infusion bottle 4, an infusion tube 5, and a flushing component.

[0030] A bottle stopper piercer is provided at one end of the infusion tube 5, and the infusion tube 5 penetrates the bottle mouth of the infusion bottle 4 through the bottle stopper piercer to be connected to the infusion bottle 4. The infusion bottle 4 and the infusion tube 5 are used together to provide an infusion function for the infusion set.

[0031] The flushing assembly is arranged on one side of the infusion tube 5 , and the flushing assembly is mainly composed of a three-way tube 3 and a needle tube 2 .

[0032] The three-way tube 3 is divided into a hose 31 connected to the needle tube 2, a connecting tube 32 connected to the infusion tube 5 and a side tube 33 connected to the infusion bottle 4. The functions of the hose 31 are, firstly, to serve as a bridge to connect the three-way tube 3 and the needle tube 2, and secondly, to transport the cleaning reagent to the connecting tube 32 and the side tube 33; and the length of the side tube 33 is the longest among the three tubes. A puncture needle 34 is provided at the port of the side tube 33. The function of the puncture needle 34 is to facilitate the side tube 33 to pass through the bottle mouth of the infusion bottle 4. The side tube 33 needs to pass through the bottle mouth and enter the top of the infusion bottle 4. The side tube 33 can transport the cleaning reagent into the infusion bottle 4. The side tube 33 is long enough not only to directly clean the entire bottle body, but also to avoid the accumulated cleaning reagent flooding the tube mouth of the side tube 33 and causing back suction when cleaning the infusion bottle 4; the connecting tube 32 needs to be connected to the position of the infusion tube 5 close to the bottle mouth. When the cleaning reagent enters the infusion tube 5 from the connecting tube 32, it can flow from the top of the infusion tube 5 to the bottom, which can effectively clean the entire infusion tube 5.

[0033] In addition, the syringe 2 can hold a cleaning reagent. Inside the syringe 2, there is also a piston 1 that facilitates the user to push the cleaning reagent. The liquid outlet port of the syringe 2 is adapted to the interface of the rubber tube 31, and the liquid outlet port of the syringe 2 has a certain length, which can be well inserted into the rubber tube 31, and the two are not easily detached after connection. The connection method between the syringe 2 and the rubber tube 31 can adopt a threaded connection. Threads can be added to the outer wall of the liquid outlet port of the syringe 2, and threads adapted to it can be added to the inner wall of the port of the rubber tube 31. When it is necessary to disassemble and assemble the syringe 2, just turn the syringe 2.

[0034] To enable the cleaning device to clean the infusion tube 5 and the infusion bottle 4 respectively, referring to Figure 3 , a liquid control valve 6 can be added to the connecting tube 32, the side tube 33, and the infusion tube 5 near the bottle mouth of the infusion bottle 4 respectively. The preferred model of the liquid control valve 6 is a medical valve of 20 - 160. Multiple of them can be set and used as reserve control valves or safety control valves. When only the infusion bottle 4 needs to be cleaned, close the liquid control valves 6 on the connecting tube 32 and the infusion tube 5, and open the liquid control valve 6 on the side tube 33. In this way, the cleaning reagent will only enter the side tube 33 and then enter the infusion bottle 4 from the side tube 33. After the cleaning is completed, then open the liquid control valve 6 on the infusion tube 5 to make the cleaning reagent flow out from the infusion tube 5, so as to initially clean the infusion tube 5; if it is also necessary or only necessary to flush and clean the infusion tube 5, open the liquid control valves 6 on the connecting tube 32 and the infusion tube 5, and close the liquid control valve 6 on the side tube 33; in this way, the cleaning reagent enters the infusion tube 5 through the connecting tube 32 to clean it and will not enter the side tube 33, and the reagent for cleaning the infusion tube 5 will directly flow out along the infusion tube 5.

[0035] Embodiment 2

[0036] As an embodiment of the present utility model:

[0037] Referring to Figure 4 , the only difference from the above Embodiment 1 is that the liquid control valve 6 is set as a flow regulator 7. The flow regulator 7 not only has the function of controlling the flow direction of the cleaning reagent like the liquid control valve 6, but also can control the flow rate of the cleaning reagent. The flow rate can be controlled by sliding the adjustment wheel on the flow regulator 7. The working principle of the flow regulator 7 is obvious to those skilled in the art and will not be described in detail in this embodiment.

[0038] In summary, a colloidal liquid infusion set with a cleaning function disclosed in this application can not only perform flushing and cleaning on the infusion tube, but also clean the infusion bottle, and has the function of separately cleaning the infusion tube and the infusion bottle. This instrument has a simple structure, reasonable design, and convenient use.

[0039] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
