Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, in particular to an infusion pump capable of preventing backflow. Background Art

[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items that are used directly or indirectly on the human body. The development of medical devices can be traced back to ancient times. In ancient times, people used various simple tools and techniques to treat diseases and trauma. With the passage of time, medical devices have continued to develop and improve. The application of infusion pumps is suitable for intensive care units, etc., and is used to deliver drugs to patients with higher accuracy over a longer period of time. A specified drug bag (infusion bag) is configured on the infusion pump, and the infusion tube hanging from the drug bag is clamped between the main body and the opening and closing door. The infusion tube is housed in the main body and the opening and closing door is closed, thereby maintaining the infusion tube.

[0003] The infusion pumps in the current prior art generally have a certain preventive effect on blood backflow, but one of the reasons is that the infusion pump is hung on the infusion stand, and the high hanging height has resistance to blood backflow, making it difficult for blood to flow back. Another reason is that the infusion pump itself is equipped with a mechanism to prevent backflow, but the generally adopted method to prevent backflow is generally chemical backflow prevention, and the infusion tube is not fixed when it is embedded in the infusion pump, so that the infusion tube may slip out of the groove where it is placed, and most infusion pumps are directly installed with metal fixing devices. Since the infusion stand is generally made of metal, it may slide during installation, causing the infusion pump to be unstable. Most infusion pumps can only be installed on the infusion stand. If the infusion pump is removed when the patient needs to move, it may cause backflow, which is not only inconvenient for the patient to move but also increases the risk of reflux. Therefore, an infusion pump that prevents backflow is proposed to solve the above-mentioned problems. Summary of the invention

[0015] Compared with the prior art, the present invention provides an infusion pump for preventing backflow, which has the following beneficial effects:

[0016] 1. The infusion pump for preventing backflow has an anti-backflow mechanism. When the infusion tube is placed in the infusion pump, the infusion tube can be placed in the first tube groove, the ultrasonic sensor, the clamp block and the second tube groove in sequence. The first rubber block, the third rubber block, the clamp block and the second rubber block can increase the friction with the infusion tube, so that the infusion tube is not easy to slip out of the groove, and the infusion condition is detected by the pressure sensor. When the infusion is abnormal, the motor starts to drive the threaded shaft to move, and the threaded shaft drives the screw rod to push the push block to move, thereby squeezing the infusion tube to prevent backflow. Fixing the infusion tube can make the liquid flow rate normal during infusion, and avoid the infusion tube from bending and shifting in the infusion pump. The mechanical anti-backflow method can quickly and accurately cut off the liquid flow, thereby preventing backflow.

[0017] 2. The infusion pump for preventing backflow, through the fixing mechanism, twists the internal threaded tube, the first threaded column is moved by the force of the second threaded column, one end of the first threaded column moves to squeeze the infusion stand, and at the same time, the fastening block is squeezed and deformed by the force of the first threaded column and drives the rubber strip to move, so as to fix the infusion pump body on the infusion stand. Through the setting of the groove, the fastening block can be stored inside the groove, so that the infusion pump is more convenient to store and take, and the rubber strip can increase the friction between the infusion pumps, so that the infusion pump is not easy to move.

[0018] 3.

The infusion situation can be checked through the display screen 3. If the infusion is abnormal, the abnormality can be detected through the indicator light 4. When the pressure sensor 706 and the ultrasonic sensor 709 sense the infusion abnormality, the indicator light 4 lights up to prompt, and then the control panel The control motor 710 is started, the motor 710 drives the threaded shaft 716 to move, the threaded shaft 716 drives the screw rod 711 to move, the screw rod 711 drives the push block 712 to move, at this time the push block 712 pushes the infusion tube to stop the infusion tube from flowing back, the ultrasonic sensor 709 can be installed inside the infusion pump body 1 by setting the limit plate 705, the power box 708 loses the force of the block 713 when the block 713 is pressed, so that the power box 708 can be taken out of the infusion pump body 1, and the third rubber block 715 is set to limit the infusion tube when the infusion tube is embedded in the ultrasonic sensor 709 to prevent the infusion tube from moving inside the infusion pump body 1.

[0030] Furthermore, the first rubber block 701 is fixedly installed on one side of the surface of the first tube groove 702, and the second rubber block 704 is fixedly installed on one side of the surface of the second tube groove 703. Through the setting of the first rubber block 701, when the infusion tube is embedded in the first tube groove 702, the first rubber block 701 increases the friction with the infusion tube so that the infusion tube is placed in the first tube groove 702, thereby limiting the infusion tube.

[0031] Furthermore, one end of the screw rod 711 is fixedly connected to the push block 712, and one end of the motor 710 is fixedly connected to one end of the threaded shaft 716. Through the setting of the screw rod 711, when the motor 710 drives the threaded shaft 716 to move, the threaded connection between the threaded shaft 716 and the screw rod 711 drives the screw rod 711 to move, so that the screw rod 711 drives the push block 712 to squeeze the infusion tube, thereby stopping the infusion tube from infusing.

[0032] Furthermore, the fixing mechanism 8 includes a limiting column 801, a groove 802 is provided on one side of the surface of the mounting plate 2, a rubber strip 803 is installed on one side of the surface of the limiting column 801, a fastening block 804 is installed on one side of the surface of the limiting column 801, the internal thread of the fastening block 804 is connected to a first threaded column 805, one end of the first threaded column 805 is fixedly connected to a second threaded column 806, and one side of the surface of the second threaded column 806 is threadedly connected to an internal threaded tube 807. Through the arrangement of the limiting column 801, the groove 802, the rubber strip 803, the fastening block 804, the first threaded column 805, the second threaded column 806 and the internal threaded tube 807, when using the infusion pump body 1 for infusion, it is necessary to first fix the infusion pump body 1 on the infusion stand, first place the infusion pump body 1 in a suitable position, and then screw the internal threaded tube 807 to screw the internal threaded tube 807 to one end of the second threaded column 806 The inner threaded tube 807 continues to be twisted. At this time, the first threaded column 805 is moved by the force of the second threaded column 806. Then, the first threaded column 805 moves so that one end of the first threaded column 805 squeezes the infusion stand. At the same time, the fastening block 804 is squeezed and deformed by the force of the first threaded column 805 and drives the rubber strip 803 to move, thereby fixing the infusion pump body 1 on the infusion stand. When the infusion pump body 1 is not needed, the first threaded column 805 can be fixed by one hand, and then the inner threaded tube 807 is twisted to remove the inner threaded tube 807 from the second threaded column 806, and then the first threaded column 805 is removed from the inside of the fastening block 804. At this time, the fastening block 804 can be pushed into the groove 802, and the rubber strip 803 follows the fastening block 804 to be installed into the inside of the groove 802. The rubber strip 803 can increase the friction with the groove 802, so that the fastening block 804 installed in the groove 802 is not easy to slip out.

[0033] Furthermore, the limiting column 801 passes through the fastening block 804, and the first threaded column 805 passes through the rubber strip 803. Through the setting of the rubber strip 803, the rubber strip 803 can increase the friction with the groove 802, so that the fastening block 804 installed in the groove 802 is not easy to slide out.

[0034] Furthermore, the rubber strip 803 is fixedly connected on one side of the surface of the fastening block 804, and the diameter of the first threaded column 805 is larger than that of the second threaded column 806. Through the setting of the first threaded column 805, when the second threaded column 806 moves, it drives the first threaded column 805 to move. The movement of the first threaded column 805 generates a force on the infusion stand, thereby fixing the infusion pump body 1 on the infusion stand.

[0035] Furthermore, the carrying mechanism 9 includes a bottle slot 901, a connecting block 902 is fixedly installed on one side of the surface of the mounting block 707, an internal threaded cover 903 is threadedly connected to one side of the surface of the bottle slot 901, a first shoulder strap 904 is fixedly connected to one side of the surface of the connecting block 902, one end of the first shoulder strap 904 is fixedly connected to an insert block 905, a limiting block 906 is fixedly installed on one side of the surface of the insert block 905, a buckle 907 is installed on one side of the surface of the insert block 905, a square groove 908 is provided on one side of the surface of the buckle 907, a mounting strip 909 is fixedly connected to one side of the surface of the mounting strip 909, an adjusting belt 910 is wound around one side of the surface of the mounting strip 909, and one end of the adjusting belt 910 is fixedly connected to a second shoulder strap 911. 910 and the second shoulder strap 911 are set. When the patient needs to move, after the fastening block 804 of the fixing mechanism 8 is stored in the interior of the groove 802, the infusion bottle can be placed in the bottle groove 901, with the bottle mouth facing downwards into the through hole opened on one side of the bottle groove 901, and then the internal thread cover 903 is screwed on the bottle groove 901, and then the adjustment belt 910 connected to one end of the second shoulder strap 911 is passed around the mounting strip 909. After the adjustment belt 910 is adjusted to a suitable position, the insert block 905 is inserted into the interior of the buckle 907, and the insert block 905 drives the limit block 906 to move. When the insert block 905 is fully inserted into the buckle 907, the limit block 906 is installed in the square groove 908. At this time, the connection between the first shoulder strap 904 and the second shoulder strap 911 is completed. At this time, the infusion pump body 1 can be carried on the back, and the patient can move. Through the setting of the connecting block 902, the first shoulder strap 904 can be fixedly installed on one side of the surface of the infusion pump body 1.

[0036] Furthermore, the limit block 906 is installed inside the buckle 907, and the limit block 906 is installed inside the square groove 908. Through the setting of the limit block 906, the limit block 906 can be embedded in the square groove 908 to limit the position of the plug block 905. When the limit block 906 is pressed, the limit block 906 loses the position limitation of the square groove 908, thereby removing the plug block 905 from the buckle 907.

[0037] Furthermore, two groups of insert blocks 905 are provided, and two groups of buckles 907 are provided. Through the provision of the insert blocks 905 , the first shoulder strap 904 is connected to the second shoulder strap 911 through the insert blocks 905 and the buckles 907 .

[0038] Working principle: before infusion, first open the infusion pump door 5, then embed the infusion tube into the first tube groove 702, the first rubber block 701 limits the infusion tube, then pass the infusion tube through one side of the mounting block 707 and place it on the surface side of the pressure sensor 706, then put the infusion tube into the clamp block 714, and then place it flat on the surface side of the power box 708, then put the infusion tube into the second tube groove 703, the infusion tube is limited by the second rubber block 704, and finally close the infusion pump door 5. The infusion situation can be checked through the display screen 3. If the infusion is abnormal, the abnormality can be detected through the indicator light 4. When the pressure sensor 706 and the ultrasonic sensor 709 sense the infusion abnormality, the indicator light 4 lights up to prompt, and then the motor 710 can be controlled by the control board 6 to start The motor 710 drives the threaded shaft 716 to move, the threaded shaft 716 drives the screw rod 711 to move, and the screw rod 711 drives the push block 712 to move. At this time, the push block 712 pushes the infusion tube to stop the infusion tube from infusing to avoid backflow. The setting of the limit plate 705 allows the ultrasonic sensor 709 to be installed inside the infusion pump body 1. The setting of the wrench block 713 makes it possible to make the power box 708 lose the force of the wrench block 713 when the wrench block 713 is pressed, so that the power box 708 can be taken out of the infusion pump body 1. The setting of the third rubber block 715 limits the position of the infusion tube when the infusion tube is embedded in the ultrasonic sensor 709 to prevent the infusion tube from moving in the infusion pump body 1. When using the infusion pump body 1 for infusion, the infusion pump body 1 needs to be fixed first. On the infusion stand, first place the infusion pump body 1 in a suitable position, then twist the internal threaded tube 807, and continue to twist the internal threaded tube 807 when the internal threaded tube 807 is twisted to one end of the second threaded column 806. At this time, the first threaded column 805 moves due to the force of the second threaded column 806, and then the first threaded column 805 moves so that one end of the first threaded column 805 squeezes the infusion stand, and at the same time, the fastening block 804 is squeezed and deformed by the force of the first threaded column 805 and drives the rubber strip 803 to move, thereby fixing the infusion pump body 1 on the infusion stand. When the infusion pump body 1 is not needed, the first threaded column 805 can be fixed with one hand, and then the internal threaded tube 807 can be twisted to remove the internal threaded tube 807 from the second threaded column 806, and then the first threaded column 805 can be removed from the fastening block The rubber strip 803 can increase the friction with the groove 802, so that the fastening block 804 installed in the groove 802 is not easy to slide out. When the patient needs to move, after the fastening block 804 of the fixing mechanism 8 is stored in the groove 802, the infusion bottle can be placed in the bottle groove 901, and the bottle mouth is placed downward into the through hole opened on one side of the bottle groove 901, and then the internal thread cover 903 is screwed on the bottle groove 901, and then the adjustment belt 910 connected to one end of the second shoulder strap 911 is passed around the installation strip 909, and after the adjustment belt 910 is adjusted to a suitable position, the plug block 905 is inserted into the buckle 907.The insert block 905 drives the limit block 906 to move. When the insert block 905 is fully inserted into the buckle 907, the limit block 906 is installed inside the square groove 908.
