Description

Technical Field

[0001] The utility model belongs to the technical field of infusion pumps, and specifically relates to a maintenance and detection tool for an infusion pump and an injection pump. Background Art

[0002] An infusion pump is an intelligent infusion device, which is a special medical device that uses mechanical driving force to accurately control the number of drops per minute of infusion or the infusion flow rate, ensuring accurate dosage and safe entry into the patient's body. The application of infusion pumps in clinical practice has greatly improved the accuracy, safety, and nursing quality of infusion. During the maintenance and detection process of infusion pumps, in order to ensure the maintenance effect and the safe use of medical equipment after repair, it is often necessary to detect the values of infusion flow and occlusion alarm pressure.

[0003] After retrieval, CN216449150U discloses a maintenance and detection tool for an infusion pump and an injection pump, including a housing. The top of the outer side of the housing is fixedly connected with a control board, and the top of the outer side of the housing is fixedly connected with a liquid crystal display. The bottom of the outer side of the housing is fixedly connected with a numeric keypad. A cavity is opened inside the housing. A measuring cup holder is fixedly connected to the inner wall of the cavity. A measuring cup is fixedly connected to the inside of the measuring cup holder.

[0004] However, through the exploration of the inventor, it is found that this technical solution still has at least the following defects: in the above device, when the water droplet sensor detects water droplets, the control board starts timing. After the detection time arrives, the control board closes the timing and closes the first electromagnetic valve, and reads the value of the measuring cup to complete the detection. Although the measuring cup can be used to receive water through the setting, the measuring cup is fixedly installed inside the housing. After the detection is completed, it is difficult for the staff to pour out the water in the measuring cup.

[0005] In view of this, the present utility model is specifically proposed. Content of the Utility Model

The following embodiments are used to illustrate the present utility model.

[0025] As Figures 1 to 5 shown

[0026] An infusion pump and syringe pump maintenance and detection tool, comprising a base 1. A placement groove 6 is formed at the top of the base 1. A measuring cup 2 is arranged in the placement groove 6. A sensor 18 is installed on the inner side of the bottom of the measuring cup 2. Symmetrically arranged limit seats 4 are fixedly connected to the outer wall of the top of the base 1, and the limit seats 4 are located on both sides of the placement groove 6. An activity groove 14 is formed on the opposite side of each of the two limit seats 4. The inner walls of the two activity grooves 14 are both slidably connected with wedge-shaped limit blocks 13. Both of the two wedge-shaped limit blocks 13 are in contact with the outer wall of one side of the measuring cup 2. Compression springs 15 are fixedly connected to the inner walls of one side of the two activity grooves 14. One end of each of the two compression springs 15 is fixedly connected to the outer wall of one of the two wedge-shaped limit blocks 13. The measuring cup 2 is slidably placed inside the placement groove 6. During the process of the measuring cup 2 moving into the placement groove 6, the measuring cup 2 presses the two wedge-shaped limit blocks 13 towards both sides until the measuring cup 2 is in contact with the inner wall of the end of the placement groove 6. At this time, under the action of the two compression springs 15, the two wedge-shaped limit blocks 13 can be pushed to move relatively, so that the two wedge-shaped limit blocks 13 are reset to the initial state, and the two wedge-shaped limit blocks 13 are in contact with the outer wall of one side of the measuring cup 2, realizing the limiting effect on the measuring cup 2. Rectangular activity openings 16 are formed at the top of both of the two limit seats 4. Push-pull rods 17 are slidably connected to the inner walls of the two rectangular activity openings 16. The bottom ends of the two push-pull rods 17 are respectively fixedly connected to the outer walls of the tops of the two wedge-shaped limit blocks 13. An installation seat 3 is fixedly arranged on the outer wall of the top of the base 1. An installation track 7 is fixedly arranged on the outer wall of one side of the installation seat 3. A lifting block 19 is slidably arranged on the inner wall of the installation track 7. A connecting rod 20 is fixedly connected to the outer wall of one side of the lifting block 19. One end of the connecting rod 20 is fixedly connected to a pipe joint 8. A liquid outlet pipe 5 is connected to the bottom of the pipe joint 8. The bottom end of the liquid outlet pipe 5 extends to the inner side of the top of the measuring cup 2. After the detection is completed, the two push-pull rods 17 are pulled to move in opposite directions. The two push-pull rods 17 drive the two wedge-shaped limit blocks 13 to move in opposite directions, so that the two wedge-shaped limit blocks 13 respectively move into the two activity grooves 14. At the same time, the pipe joint 8 is lifted through the arranged installation track 7, the lifting block 19 and the connecting rod 20, so that the pipe joint 8 drives the liquid outlet pipe 5 to move upward. Then the measuring cup 2 can be slid out of the placement groove 6, which is convenient for the staff to pour out the water in the measuring cup 2.

[0027] In a specific embodiment, a liquid guiding hose 21 is connected to the top end of the pipeline joint 8. A first infusion tube 11 and a liquid inlet tube 23 are fixedly installed on the top of the mounting seat 3. The first infusion tube 11 is communicated with the liquid guiding hose 21. A liquid receiving head 24 is connected to the end position of the liquid inlet tube 23. A three-way joint 25 is fixedly installed on the top of the mounting seat 3. The opposite ends of the first infusion tube 11 and the liquid inlet tube 23 are respectively connected to both ends of the three-way joint 25. A first electromagnetic valve 22 is installed on the first infusion tube 11. Before the measuring cup 2 is placed in the placing groove 6, the pipeline joint 8 is lifted by the arranged mounting rail 7, lifting block 19 and connecting rod 20, so that the pipeline joint 8 drives the liquid outlet pipe 5 to move upward. After the measuring cup 2 is limited, the pipeline joint 8 is released, so that the bottom end of the liquid outlet pipe 5 descends to the inner side of the top of the measuring cup 2. Then, the interface of the infusion pump is connected to the liquid receiving head 24 through a pipeline. When the flow rate needs to be detected, the first electromagnetic valve 22 is opened and the second electromagnetic valve 26 is closed through the control panel 10, so that the water flow can flow through the liquid receiving head 24, liquid inlet tube 23, three-way joint 25 and first infusion tube 11 to the liquid guiding hose 21, and then flow through the liquid guiding hose 21, pipeline joint 8 and liquid outlet pipe 5 into the measuring cup 2. When the sensor 18 detects water droplets, the control panel 10 starts timing. After the detection time arrives, the control panel 10 closes the timing and closes the first electromagnetic valve 22. Then, the value of the measuring cup 2 is read to complete the detection. A precision pressure gauge 9 is fixedly installed on the outer wall of one side of the mounting seat 3. A second infusion tube 12 is connected to the precision pressure gauge 9. The second infusion tube 12 is communicated with the three-way joint 25. A second electromagnetic valve 26 is installed on the second infusion tube 12. A control panel 10 is fixedly installed on the outer wall of one side of the mounting seat 3. The second electromagnetic valve 26, first electromagnetic valve 22 and sensor 18 are all electrically connected to the control panel 10. When the value of the occlusion alarm pressure needs to be detected, the second electromagnetic valve 26 is opened and the first electromagnetic valve 22 is closed through the control panel 10, so that the water flow can flow through the liquid receiving head 24, liquid inlet tube 23 and three-way joint 25 into the second infusion tube 12, and then flow through the second infusion tube 12 to the precision pressure gauge 9. After the measured pump alarms, the value of the precision pressure gauge 9 is read to complete the detection.

[0028] The implementation principle of the infusion pump and syringe pump maintenance and detection tool in this embodiment is as follows:

[0029] During specific use, the measuring cup 2 is slid and placed inside the placement groove 6. During the process of the measuring cup 2 moving into the placement groove 6, the measuring cup 2 squeezes the two wedge-shaped limit blocks 13 towards both sides until the measuring cup 2 contacts the inner wall of the end of the placement groove 6. At this time, under the action of the two compression springs 15, the two wedge-shaped limit blocks 13 can be pushed to move relative to each other, so that the two wedge-shaped limit blocks 13 return to the initial state, and the two wedge-shaped limit blocks 13 contact the outer wall of one side of the measuring cup 2, realizing the limiting effect on the measuring cup 2. Before the measuring cup 2 is placed in the placement groove 6, the pipeline joint 8 is lifted by the arranged installation track 7, lifting block 19 and connecting rod 20, so that the pipeline joint 8 drives the liquid outlet pipe 5 to move upward. After the measuring cup 2 is limited, the pipeline joint 8 is released, so that the bottom end of the liquid outlet pipe 5 drops to the inner side of the top of the measuring cup 2. Then, the interface of the infusion pump is connected to the liquid receiving head 24 through a pipeline. When the flow rate needs to be detected, the first solenoid valve 22 is opened and the second solenoid valve 26 is closed through the control panel 10, so that the water flow can flow through the liquid receiving head 24, liquid inlet pipe 23, three-way joint 25 and the first infusion pipe 11 to the liquid guide hose 21, and then through the liquid guide hose 21, pipeline joint 8 and liquid outlet pipe 5 to the measuring cup 2. When the sensor 18 detects water droplets, the control panel 10 starts timing. After the detection time arrives, the control panel 10 stops timing and closes the first solenoid valve 22, and then reads the value of the measuring cup 2 to complete the detection. After the detection is completed, the two push rods 17 are pulled to move in the opposite direction, and the two push rods 17 drive the two wedge-shaped limit blocks 13 to move in the opposite direction, so that the two wedge-shaped limit blocks 13 respectively move into the two movable grooves 14. At the same time, the pipeline joint 8 is lifted by the arranged installation track 7, lifting block 19 and connecting rod 20, so that the pipeline joint 8 drives the liquid outlet pipe 5 to move upward. Then, the measuring cup 2 can be slid out of the placement groove 6, which is convenient for the staff to pour out the water in the measuring cup 2. When the value of the occlusion alarm pressure needs to be detected, the second solenoid valve 26 is opened and the first solenoid valve 22 is closed through the control panel 10, so that the water flow can flow through the liquid receiving head 24, liquid inlet pipe 23 and three-way joint 25 into the second infusion pipe 12, and then through the second infusion pipe 12 to the precision pressure gauge 9. After waiting for the measured pump to alarm, reading the value of the precision pressure gauge 9 can complete the detection.
