Description

Technical Field

[0001] The present application relates to the technical field of infusion devices, and in particular to a multi-mode controlled infusion device. Background Art

[0002] An IV set, often simply called an infusion set, is a medical device used to deliver medication or fluids into a patient's body through a vein.

[0003] When a traditional infusion set is used, the medicine needle can only be inserted into one medicine bottle first. However, patients generally need to use multiple bottles of medicine. Therefore, the nurse needs to check the patient's infusion status at intervals so that the medicine bottle can be replaced at any time. When replacing the medicine bottle, the medicine needle needs to be reinserted into another medicine bottle. The operation is relatively troublesome and greatly consumes the nurse's energy.

[0004] The patent with the patent authorization announcement number CN113368335B discloses a functional infusion set, including a bottle stopper puncture device, a drip bucket, a flow regulator and an intravenous infusion needle connected in sequence by a hose, an air filter is connected to the side wall of the bottle stopper puncture device through an air inlet pipe, and a one-way air inlet valve is provided on the air inlet pipe, and the one-way air inlet valve is opened toward the side of the bottle stopper puncture device. When in use, the external air enters the hard container through the air filter and the air inlet pipe to balance the internal and external air pressure of the hard container. When a large amount of drugs are mixed into the hard container and the pressure is too high, the bottle stopper puncture device is inserted into the hard container at this time, and the pressure in the hard container will force the drug into the air inlet pipe. The drug liquid will not easily contact the air filter membrane of the air filter under the obstruction of the one-way air inlet valve, so it is not easy for the drug liquid to leak from the air filter membrane, and the normal use of the infusion set is not easily affected. The reliability of the use of the infusion set is high. It has the following problems: when changing the drugs, nurses need to perform manual operation, which is time-consuming and labor-intensive.

The medicine needle 201, the cover 202 and the flow regulating valve 205 all adopt the structure of a traditional infusion set, the cover 202 is an exhaust structure, the medicine needle 201 is used to connect to the infusion bottle , and the needle 207 is used for intravenous injection, and the liquid medicine filter 206 is an additional structure, which includes a round frame, and an air check valve is installed on the side of the round frame, which is used to filter air during the infusion to avoid mixing with the liquid medicine. A convex tube connected to the hose 203 is fixedly installed at the bottom of the drip pot 204, and a liquid inlet groove is constructed on the top of the convex tube. When the liquid medicine enters the drip pot 204, it will first fill up half of the drip pot 204.

The slide bar 4041 is made of elastic plastic material. It should be noted that the number of the limiting grooves 30131 is consistent with the number of the shunt cannula 303 and the positions are arranged in sequence opposite to the shunt cannula 303, so as to clamp and limit the slide bar 4041, and one side of the limiting groove 30131 is configured with an inclined surface, and the side of the slide bar 4041 opposite to the inclined surface is configured with a useful At the bevel that fits the inclined surface, when the toggle block 4042 needs to move, the bevel on the slide bar 4041 will slide with the bevel, so that the slide bar 4041 will bend downward, thereby disengaging from the limiting groove 30131, and then entering the strip groove 3013 to slide until it enters another limiting groove 30131 for elastic reset, so as to clamp the position of the slide bar 4041. This setting can make the slide bar 4041 move and stop accurately in the limiting groove 30131. At this time, the liquid inlet hole 403 on the sealing circular plate 402 can be accurately connected with the other shunt cannula 303, ensuring the smooth progress of infusion and increasing the safety of the device.

[0043] like Figure 3-Figure 4 As shown, in some embodiments, the connecting rod 501 includes a sliding sleeve 5011 that is slidably sleeved on the support rod 102, a fastening screw button 5012 is installed through a thread on the sliding sleeve 5011, an outer tube 5013 is fixedly connected to one side of the sliding sleeve 5011, an inner rod 5014 is slidably inserted in the outer tube 5013, a fixing bolt 5015 that abuts against the inner rod 5014 is installed through a thread on one side of the outer tube 5013, a connecting groove 5016 is configured at the end of the inner rod 5014, and a fixing screw 5015 that is clamped in the connecting groove is fixedly connected to the upper side of the disk body 3011. The connecting plug plate 8 in 5016 can conveniently adjust the overall height of the connecting rod 501 by providing a sliding sleeve 5011 and a tightening screw button 5012, and the outer tube 5013 and the inner rod 5014 are telescopically coordinated to adjust the position of the diverter plate 301, and then the fixing piece 502 at the end of the inner rod 5014 is connected and fixed to the connecting plug plate 8 to ensure that the diverter plate 301 can be in a parallel state and the position is stable, which facilitates the subsequent replacement of infusion operations and increases the flexibility and safety of the device.
