Description

Technical Field

[0001] The present invention relates to the technical field of anesthesia analgesia pump configuration, and particularly to a simple medicine injector for anesthesia analgesia pump configuration. Background Art

[0002] An anesthesia analgesia pump is a liquid infusion device used to provide continuous drug infusion after surgery or in specific pain situations to relieve the pain of patients. The working principle of the anesthesia analgesia pump is to administer drugs in small amounts through the mechanical resilience of the liquid storage sac to maintain the stability of the blood drug concentration, thereby achieving the effect of continuous analgesia. Patients can adjust the infusion volume of the drug by themselves through the self-controlled drug administration button according to their pain level. It is commonly used for postoperative and childbirth pain management. By continuously infusing anesthetic drugs or analgesic drugs, it helps patients control pain, improve postoperative comfort, and promote early recovery.

[0003] When using an anesthesia analgesia pump, it is necessary to first inject various analgesic and anesthetic drugs into the liquid storage sac of the analgesia pump. The traditional drug injection method usually uses a syringe manually to draw various medicaments in sequence for injection. This method of configuring drugs has low efficiency, and the medicaments may not be fully mixed, affecting the use effect of the medicaments. For this reason, we propose a simple medicine injector for anesthesia analgesia pump configuration to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the disadvantages existing in the prior art, such as: traditional drug configuration requires sequential extraction and injection of medicaments, with low efficiency and general drug mixing effect, and to propose a simple medicine injector for anesthesia analgesia pump configuration.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

Two inserting plates are symmetrically and fixedly arranged on the side wall of the upper shell close to the lower shell. Slots corresponding to the two inserting plates are opened on the lower shell. Fixing mechanisms corresponding to the inserting plates are arranged in both of the two slots. A plurality of arc-shaped tubes are circumferentially and fixedly arranged on the inner wall of the upper shell. A plurality of medicine suction tubes are circumferentially and fixedly arranged on the upper shell. All of the plurality of medicine suction tubes penetrate through the upper wall of the upper shell. The plurality of medicine suction tubes are respectively communicated with the plurality of arc-shaped tubes. A medicine suction head is fixedly arranged at one end of each arc-shaped tube away from the upper shell. A piston plate is slidably arranged in each arc-shaped tube. A limiting mechanism corresponding to the piston plate is arranged in each arc-shaped tube. A switch mechanism corresponding to the piston plate is further arranged on the piston plate. A medicine mixing mechanism is also arranged on the upper shell. An air extractor is fixedly arranged on the side wall of the lower shell. The air extraction port of the air extractor extends into the lower shell. A medicine injection port is further fixedly arranged on the lower wall of the lower shell. A sealing cover is arranged on the medicine injection port. A sealing strip is fixedly arranged on the side wall of the upper shell close to the lower shell.

[0007] Preferably, the fixing mechanism includes two clamping blocks. Telescopic grooves corresponding to the clamping blocks are opened on the side walls of the two slots. The two clamping blocks are respectively slidably arranged in the two telescopic grooves. And the two clamping blocks are respectively connected with the inner walls of the telescopic grooves through first springs. Grooves corresponding to the clamping blocks are opened on the side walls of the two inserting plates. The side walls of the two clamping blocks close to the openings of the slots are both inclined. A pulling mechanism corresponding to each clamping block is arranged on each clamping block.

[0008] Preferably, the pulling mechanism includes two pull rods. The two pull rods are respectively fixedly arranged on the side walls of the two clamping blocks close to one ends of the first springs. And the two pull rods respectively penetrate through the side wall of the lower shell in a sliding manner. A pull handle is fixedly arranged at one end of the pull rod away from the clamping block.

[0009] Preferably, the limiting mechanism includes a plurality of limiting plates. Slide grooves corresponding to the limiting plates are opened on the side walls of each arc-shaped tube close to the inner wall of the upper shell. The plurality of limiting plates are respectively slidably arranged in the plurality of slide grooves. And threaded rods are rotatably arranged in each of the slide grooves. The plurality of threaded rods respectively penetrate through the limiting plates in a rotating manner. Threaded through holes corresponding to the threaded rods are opened on each limiting plate. One end of each threaded rod rotates through the upper wall of the upper shell and is fixedly connected. A rotating handle is arranged. Sealing sleeves are fixedly arranged on the side walls of each piston plate. The plurality of sealing sleeves are respectively slidably sleeved on the plurality of threaded rods.

[0010] Preferably, the switch mechanism includes a number of baffles. Each piston plate is provided with a liquid outlet, and the number of baffles respectively cover the number of liquid outlets. A connecting plate is fixedly arranged on the side wall of each baffle. Each connecting plate is connected to the side wall of the piston plate through a second spring, and a push rod is fixedly connected to the end of each connecting plate away from the baffle. The push rod slidably penetrates through the piston plate, and the number of push rods are respectively arranged corresponding to the number of limiting plates. A sealing glue is coated on the side wall of each push rod.

[0011] Preferably, the medicine mixing mechanism includes a number of stirring rods.

The rotating rod rotates through the upper wall of the upper shell and extends into the lower shell, and the number of stirring rods are circumferentially fixedly arranged on the side wall of the rotating rod.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: By providing a plurality of medicine suction tubes, it is possible to simultaneously suck a variety of medicines. Through the cooperation of the threaded rod and the limiting plate, the position of the piston plate is limited. By adjusting the position of the limiting plate, the suction amount of various liquid medicines can be controlled. When the air pump pumps air, it will pull each piston plate to slide and suck the medicine. After the piston plate reaches the position of the limiting plate, the medicine suction head can be pulled out to stop sucking the medicine. In order to ensure that the air pump continues to suck liquid in other arc-shaped tubes, it is necessary to seal the medicine suction head with the qualified amount of medicine. When the piston plate reaches the limiting plate, the limiting plate will push up the push rod, thereby driving the baffle to rise, and then the liquid outlet can be opened, so that the medicine in the arc-shaped tube can be sucked into the lower shell. After the medicines in each arc-shaped tube all fall into the lower shell, the motor can be started to drive the stirring rods to stir, so as to complete the full mixing of the medicine. Then, by opening the medicine injection port, the fully mixed medicine can be injected into the liquid storage bag of the analgesic pump, thereby completing the configuration of the medicine in the analgesic pump. There is no need to perform multiple operations of sucking and injecting the medicine, which greatly improves the efficiency of medicine preparation, and the medicine is fully mixed, ensuring the use effect of the medicine.
