Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a disposable dual-chamber infusion set. Background Technology
[0002] Intravenous infusion is a method of delivering large quantities of sterile fluids, electrolytes, and medications into the body via a vein, utilizing atmospheric pressure and hydrostatic pressure. The injection of large amounts of fluids, electrolytes, or blood into a vein is called intravenous infusion. Depending on the injection site and the type of fluid being infused, it can be categorized as peripheral intravenous infusion, central venous infusion, total parenteral nutrition (TPN) infusion, and blood transfusion.
[0003] Currently, when patients need to be resuscitated with intravenous medication, medical staff need to remove the infusion set or inject the medication from the other end of the cannula. If the medication is injected from the other end of the cannula, the medical staff also need to pinch the infusion tube to prevent the medication from flowing upwards.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a disposable dual-chamber infusion set in order to achieve a more practical value. Utility Model Content
[0005] (a) Technical problems to be solved

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a disposable dual-chamber infusion set, comprising a puncture device fixedly connected to one end of an infusion tubing, a connector fixedly connected to the other end of the infusion tubing, an infusion chamber movably sleeved at one end of the connector, a drug delivery chamber integrally formed on the outer side of the infusion chamber, a partition rotatably installed on the inner side of the infusion chamber, a sealing ring sleeved on the outer side of the partition, and the sealing ring contacting the inner wall of the infusion chamber.
[0009] As a preferred embodiment of this utility model of a disposable dual-chamber infusion set, a flow regulating valve is sleeved on the outside of the infusion tubing, a drip chamber is fixedly installed on the outside of the infusion tubing, an intravenous needle is integrally injection molded at the bottom of the infusion chamber, and an intravenous needle tip is fixedly installed at one end of the intravenous needle.
[0010] In a preferred embodiment of this invention, the drug delivery chamber is connected to the infusion chamber, and a heparin cap is fitted onto the inner side of one end of the drug delivery chamber.
[0011] As a preferred embodiment of this invention, a disposable dual-chamber infusion set has an adjustment seat integrally injection molded on the outer side of the infusion chamber, an adjustment groove is provided on one side of the adjustment seat, and friction texture is provided on the surface of the adjustment groove.
[0012] In a preferred embodiment of this invention, a connecting column is rotatably mounted on the inner side of the adjusting seat, a rotating plate is fixedly mounted on the outer side of the connecting column, and the other end of the connecting column is fixedly connected to the partition.
[0013] (III) Beneficial Effects
[0014] This invention provides a disposable dual-chamber infusion set. It has the following beneficial effects:
[0015] In this invention, the design of the infusion chamber and the medication infusion chamber allows for intravenous injection during resuscitation. By rotating the rotating plate, the diaphragm and sealing ring rotate. When intravenous injection is needed, the diaphragm and sealing ring can block the infusion chamber, preventing the injected medication from flowing back into the infusion tubing. This allows medical staff to directly inject the medication without pinching the tubing or separating the infusion set, making the operation convenient and beneficial for resuscitating patients.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0022] This utility model embodiment provides a disposable dual-chamber infusion set, such as... Figure 1-4As shown, it includes a puncture device 2 fixedly connected to one end of the infusion tubing 1, a connector 5 fixedly connected to the other end of the infusion tubing 1, an infusion chamber 6 movably sleeved at one end of the connector 5, a drug delivery chamber 7 integrally provided on the outer side of the infusion chamber 6, a partition 11 rotatably installed on the inner side of the infusion chamber 6, a sealing ring 12 sleeved on the outer side of the partition 11, and the sealing ring 12 contacting the inner wall of the infusion chamber 6.
[0023] By setting up an infusion chamber 6, a drug delivery chamber 7, a diaphragm 11, and a sealing ring 12, the design of the infusion chamber 6 and the drug delivery chamber 7 facilitates intravenous injection during emergency treatment. By rotating the rotating plate 14, the diaphragm 11 and the sealing ring 12 can be rotated, which can block the passage of the infusion chamber 6, preventing the injected drug from flowing back into the infusion tubing 1, and making it convenient for medical staff to directly inject drugs.
[0024] A flow regulating valve 4 is sleeved on the outside of the infusion tubing 1, and a drip chamber 3 is fixedly installed on the outside of the infusion tubing 1. An intravenous needle tube 8 is integrally injection molded at the bottom of the infusion chamber 6, and an intravenous needle tip 10 is fixedly installed at one end of the intravenous needle tube 8.
[0025] The flow rate of the medication can be adjusted and controlled by the flow regulating valve 4. The medication can be delivered to the patient via the drip chamber 3, the intravenous needle 8, and the intravenous needle 10.
[0026] The infusion chamber 7 is connected to the infusion chamber 6, and a heparin cap 9 is fitted inside one end of the infusion chamber 7.
[0027] By setting up the heparin cap 9, when intravenous injection is required, medical staff can directly puncture the heparin cap 9 with the syringe needle, push the drug solution through the infusion chamber 7 to the intravenous catheter 8 and the intravenous needle 10, and inject the drug solution into the patient through the intravenous needle 10 for emergency treatment, which facilitates the drug infusion operation during emergency treatment.
[0028] An adjustment seat 13 is integrally injection molded on the outer side of the infusion chamber 6. An adjustment groove 15 is provided on one side of the adjustment seat 13, and friction texture is provided on the surface of the adjustment groove 15. A connecting column 16 is rotatably installed on the inner side of the adjustment seat 13. A rotating plate 14 is fixedly installed on the outer side of the connecting column 16. The other end of the connecting column 16 is fixedly connected to the partition 11.
[0029] By setting up a rotating plate 14, an adjusting groove 15, and a connecting column 16, it is easy to rotate the rotating plate 14 to drive the connecting column 16 and the partition 11 to rotate, so that the partition 11 and the sealing ring 12 block the infusion chamber 6, so that the medicine injected through the infusion chamber 7 can be directly delivered to the patient through the intravenous needle tube 8 and the intravenous needle 10. The partition 11 and the sealing ring 12 can prevent the injected medicine from flowing back into the infusion tubing 1, which is convenient to operate and allows the medicine to be added quickly.
[0030] In summary, when intravenous injection is required, it is convenient for medical staff to directly puncture the heparin cap 9 with the syringe needle. Through the design of the infusion chamber 6 and the drug infusion chamber 7, intravenous injection can be performed during resuscitation. Then, by rotating the rotating plate 14, the diaphragm 11 and the sealing ring 12 can be rotated, which can block the channel of the infusion chamber 6 and prevent the injected drug from flowing back into the infusion tubing 1, making it convenient for medical staff to directly inject the drug. In resuscitation, the drug can be quickly injected, which is convenient for resuscitating patients.
