Description

Technical Field

[0001] The utility model relates to the technical field of infusion sets, in particular to a disposable automatic exhaust precision infusion set. Background Art

[0002] A disposable infusion set is a common medical consumable, mainly used to establish a channel between the vein and the drug solution for intravenous infusion. It consists of multiple connected parts, including an intravenous needle or injection needle, a needle cap, an infusion hose, a drug filter, a flow rate regulator, a drip pot, a bottle stopper puncture device and an air filter. Some infusion sets are also equipped with functional components such as injection parts and drug addition ports.

[0003] If a disposable infusion set is not properly vented, it may have a range of adverse effects on the patient.

[0004] First, if the infusion set is not vented, air may enter the blood vessels and form air embolism. Air embolism can block blood vessels, leading to interruption of blood supply, which may cause symptoms such as dyspnea and chest pain, and may even be life-threatening in severe cases. Therefore, air embolism is the most dangerous situation when the infusion set is not vented; secondly, the air in the infusion set may also affect the infusion speed. The air occupies a certain space in the infusion tube, which affects the flow rate of the liquid, may cause the infusion speed to decrease, and affect the treatment effect; in addition, a large amount of air entering the blood vessels may also cause discomfort to the patient, such as headache, nausea, etc.; finally, if there is air in the infusion tube, the drug may not fully enter the patient's body, resulting in insufficient drug dosage, which affects the treatment effect and causes drug waste.

[0005] To avoid these potential risks, medical staff will carefully check whether the infusion set has been vented before starting the infusion, ensure that the infusion set and infusion tube are properly connected, and remove the air in them. Some hospitals also use special air detectors to ensure that there is no air in the infusion set.

[0006] The exhaust steps of the existing disposable infusion set are:

[0007] 1 Check the infusion set: whether it is complete and undamaged, and make sure that all interfaces are in a closed state; 2 Connect the infusion bottle: insert the needle end of the infusion set into the rubber stopper of the infusion bottle, and ensure that the connection is tight to prevent leakage; 3 Open the regulator: open the regulator on the infusion tube and keep it in an open state so that the liquid can flow smoothly; 4 Invert the infusion bottle: invert the infusion bottle so that the bottle mouth faces downward so that the liquid can flow into the small pot of the infusion set; 5 Squeeze the infusion tube: gently squeeze the infusion tube to help the liquid flow into the small pot and expel the air in it. At the same time, you can observe the liquid in the small pot to ensure that there are no bubbles. 6 Stand the infusion bottle upright: when the liquid in the small pot reaches a certain height, stand the infusion bottle upright so that the liquid flows naturally into the infusion tube; 7 Close the regulator: after the liquid starts to flow into the infusion tube, close the regulator to control the infusion speed; 8 Check the infusion tube: Finally, check whether there are still bubbles in the infusion tube. If there are any, you can gently squeeze the infusion tube to move the bubbles into the small pot, and open the regulator again to let the liquid expel the bubbles.

[0008] The existing exhaust method has the following technical problems: the steps are complicated, the operation is not convenient, and the exhaust cannot be performed automatically in real time. During the input of the medicine liquid, the volume of the external gas needs to be continuously exchanged with the medicine in the medicine bottle in the drip bucket so that the medicine in the medicine bottle can be continuously output. Therefore, when the gas enters the medicine bottle, bubbles will be generated in the medicine in the drip bucket. The medicine with bubbles may be input into the human body through the infusion tube, thereby posing a safety hazard.

[0009] Therefore, a disposable automatic exhaust precision infusion set is designed to solve the above problems. Summary of the invention

Figure 3 As shown, a liquid outlet dropper 7-1 is provided at the center of the upper cover of the exhaust drip hopper cover 7, and the upper part of the liquid outlet dropper 7-1 is connected to the short tube 4, and the lower part of the exhaust drip hopper cover 7 is sleeved on the drip hopper 8; Figure 3 As shown, the inner wall of the exhaust drip hopper cover 7 is provided with an exhaust hole 7-2 which is attached to the wall and penetrates from top to bottom inside and outside, and the outer wall at the top of the exhaust drip hopper cover 7 is provided with an exhaust membrane groove which opens upward, and the top opening of the exhaust hole 7-2 is connected to the exhaust membrane groove, and the exhaust membrane groove is provided with an exhaust membrane 6, and the exhaust plug 5 is inserted in the exhaust membrane groove, and the center of the exhaust plug 5 is penetrated from top to bottom for compacting the exhaust membrane 6 into the exhaust membrane groove;

[0033] The following is the prior art and will not be described in detail. Figure 1 As shown, the drip funnel 8 is connected to a long infusion tube 9, a regulator 10 is provided on the long infusion tube 9, and a terminal end of the long infusion tube 9 is connected to an intravenous infusion needle 12 via a spiral coupling 11.

[0034] Furthermore, the air filter 2, the exhaust drip funnel cover 7 and the spiral two-way valve 11 are all made of ABS.

[0035] Preferably, the exhaust pipe 3 is made of HDPE.

[0036] Particularly, the short tube 4 , the drip bucket 8 and the long tube 9 of the infusion device are made of PVC.

[0037] Particularly, the exhaust plug 5 is made of one of PVC, PP or sintered PE.

[0038] Preferably, the exhaust membrane 6 is made of glass fiber or PTFE.

[0039] Particularly, the material of the regulator 10 is ABS or PE.

[0040] In particular, the exhaust plug 5 is provided with color, which is easy to identify, and can prevent clinicians from mistaking it for a drug addition port, thereby preventing misoperation.

[0041] Directions:

[0042] After puncturing the medicine bottle, the liquid medicine in the medicine bottle passes through the short tube 4, and the gas in the short tube 4 is discharged through the exhaust pipe 3 and the air filter 2; the liquid medicine then enters the dripping funnel 8 through the liquid outlet dropper 7-1, and the air in the dripping funnel 8 is discharged to the outside through the exhaust hole 7-2 of the exhaust dripping funnel cover 7 and the exhaust membrane 6, and the exhaust plug 5 plays the role of pressing the exhaust membrane;

[0043] When the amount of liquid medicine in the dripping funnel 8 increases to the point where the upper liquid level submerges the lower end of the exhaust hole 7-2, the liquid level blocks the exhaust hole 7-2, and a closed space is formed in the dripping funnel 8. At this point, the liquid medicine stops entering the dripping funnel 8, and the liquid level remains unchanged, completing the filling of the dripping funnel 8 with liquid medicine.

[0044] The liquid medicine in the drip bucket 8 passes through the long tube 9 of the infusion set, and the liquid medicine will flow naturally along the pipeline of the long tube 9 of the infusion set, and the air will be squeezed out at the same time. After the liquid flows out from the intravenous infusion needle 11, the intravenous infusion needle 11 is inserted into the human vein, and the liquid medicine is injected into the human body through the intravenous infusion needle 11.
