Infusion set stopper puncture device 4.

In clinical use, the

liquid medicine containers

21 and 22 are fixed on the automatic bottle changer turntable 31, and the fixed structure 14 of the converter 1 is fixedly fixed with the automatic bottle changing machine fixing structure 321 to insert and convert the infusion set stopper puncture device 4 into the conversion. The soft plug 12 is then activated, and the automatic bottle changer 31 is automatically rotated to move the liquid medicine container 21 directly above the converter stopper puncture device 11, and the automatic bottle changing machine fixing structure 321 is automatically moved up. The converter stopper puncture device 11 is inserted into the liquid medicine container 21, and the atmosphere gas passes through the converter bottle stopper air filter film 113 and the converter bottle stopper air passage 112, and enters the liquid medicine container 21, and the liquid medicine container 21 The liquid flows down from the converter stopper puncture liquid passage 111 and enters the converter chamber 13 through the converter dropper 15, since the only liquid outlet at the bottom of the converter chamber 13 is the longitudinal side hole 162 of the converter constant height connection tube 16, The longitudinal side hole 162 has a small aperture, and the liquid temporarily cannot overcome the surface tension through the longitudinal side hole 162, and can only accumulate in the converter cavity 13 continuously, the liquid level continues to rise, and the gas in the converter cavity 13 can pass through the longitudinal side. Hole 162 Loose discharge, when the liquid rises to completely cover the upper edge of the longitudinal side hole 162, the gas cannot continue to be discharged, and the pressure in the converter chamber 13 rises, causing the liquid to overcome the surface tension of the longitudinal side hole 162, forcibly entering the longitudinal side hole 162. And flowing down, the liquid height in the converter cavity 13 is not Further raising, that is, the converter fixed height connecting pipe 16 achieves the desired liquid level setting effect, and the cap 161 of the converter fixed height connecting pipe 16 can prevent the liquid from directly blocking the longitudinal side hole 162, thereby avoiding the liquid level constant failure. After the liquid leveling is successful, it continues to flow into the converter squeeze section 17, the converter gas detection section 18, the transducer ultrasonic induction section 19, and finally into the infusion set stopper puncture device 4, completes the venting, and begins the infusion.

During the infusion process, the automatic bottle changer drip rate detecting system 322 can read the number of drops per minute of the converter dropper 15, that is, the flow rate, and then feed back to the automatic bottle changing machine speed control system 324, by squeezing the converter The pressing of the pressure section 17 adjusts the flow rate. The automatic ultrasonic transducer system 326 can be applied to the transducer ultrasonic sensing section 19 to ablate the air bubbles and increase the temperature of the liquid.

When the liquid medicine container 21 is drained, the dropper speed of the converter dropper 15 is reduced to zero, and the automatic bottle changer drip rate detecting system 322 will start the automatic bottle changing action or issue an alarm within the set time. If the mechanism fails, the liquid level in the converter chamber 13 drops, and the automatic bottle changer level detection system 323 will initiate an automatic bottle changing action or an alarm within a set time. If the mechanism also fails, the liquid level continues to drop and the automatic bottle changer gas detection system 325 will detect and initiate an automatic bottle changing action or an alarm within a set time.

Once the automatic bottle changing mechanism is activated, the automatic bottle changing machine fixing structure 321 is automatically moved down, the converter bottle stopper puncture device 11 is pulled out of the liquid medicine container 21, and then the automatic bottle changing machine turntable 31 is rotated to remove the liquid medicine container 21, The chemical solution container 22 is moved directly above the converter stopper puncturing device 11, the automatic bottle changing machine fixing structure 321 is automatically moved up, and the converter stopper puncturing device 11 is inserted into the chemical liquid container 22 to continue the infusion.

When the drug solution container 22 is also drained, an alarm is triggered to inform the nurse to end the infusion, and the automatic bottle changer speed control system 324 acts on the transducer squeeze section 17 to reduce the flow rate to zero.

One of ordinary skill in the art will recognize that the above embodiments are only used The invention is not intended to limit the invention, and variations and modifications of the above embodiments are intended to fall within the scope of the appended claims.
