Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an infusion pump which has good stability and is convenient to move. Background Art

[0002] An infusion pump is an intravenous system used to deliver liquid medication or nutrient solutions to patients at a controlled rate. An infusion pump can precisely control the flow rate and volume of the liquid, improve the safety and accuracy of the infusion process, reduce human errors, and ensure that patients receive the correct treatment. An infusion pump usually consists of a pump head, infusion line, control panel, and power supply, and is commonly used in medical environments such as operating rooms, intensive care units, emergency rooms, and wards.

[0003] When using the existing infusion pump, medical staff need to press the infusion tube into the clamping device first. There are multiple sensors and peristaltic structures arranged in the same row as the clamping device, which are used to monitor and control parameters such as pressure, flow rate, pipeline blockage, and liquid flow during the infusion process. In order to avoid poor contact between some sensors and the infusion tube during the infusion process, the medical staff usually press the position of the infusion tube at each sensor after pressing the infusion tube. This is not only troublesome, but may also cause the infusion tube between one pressing point and another pressing point to tilt, thereby causing unstable flow rate. In addition, when the patient needs to get up and move around, the fixing structure of the infusion pump needs to be loosened from the infusion rod. The fixing structure of the existing infusion pump usually consists of a buckle and a screw rod. When the screw rod is tightened and loosened, a large force is usually required to avoid the situation where the infusion pump and the infusion rod are not firmly fixed, which brings a lot of difficulties to medical staff.

[0004] In the utility model patent with Chinese patent number 202121263289.8, a portable infusion pump is disclosed, including an infusion pump body, a clamping part is arranged on the infusion pump body, a positioning mechanism is arranged above the clamping part, and a suspension mechanism and a storage part for accommodating the suspension mechanism are arranged on one side of the positioning mechanism. The positioning mechanism includes a first clamping member and a second clamping member arranged opposite to the first clamping member, the first clamping member is fixedly arranged, the second clamping member is slidingly arranged, the second clamping member moves in a direction close to or away from the first clamping member, and the infusion tube passes between the first clamping member and the second clamping member. The positioning mechanism limits the infusion tube, and then puts the infusion tube into the clamping place, and finally closes the clamping part. The positioning mechanism is used to fix one side of the infusion tube, which is convenient for the infusion tube to be placed. Compared with fixing both ends, it is more convenient to put the infusion tube into the clamping place by setting the positioning mechanism, reducing the difficulty of operation.

[0005] Regarding this related technical patent, the inventor believes that: when the clamping device in the device clamps the infusion tube, the medical staff needs to manually drag the second clamping piece to clamp the infusion tube, which is more troublesome to operate and does not have the function of pressing the infusion tube. After the infusion tube is installed in the device, if it does not fit tightly with each sensor, it may cause poor contact problems.

[0006] In the utility model patent with Chinese patent number 202221777672.X, a portable infusion pump is disclosed, including an infusion pump body, a support mechanism is provided on one side of the infusion pump body, the support mechanism includes two ears fixedly connected to the top of one side of the infusion pump body and symmetrically arranged, a bearing is provided through the front of the ear seat, a rotating rod is provided on the front of the ear seat, and a connecting plate fixedly connected to the rotating rod is provided on one side of the infusion pump body, one end of one of the rotating rods is connected to a limiting assembly, the limiting assembly includes a fixed ring fixedly sleeved on one end of one of the rotating rods, and a slip ring is provided on the outside of the fixed ring. When the utility model is in use, it is convenient to support the patient's hands when the patient is walking or going to the bathroom, to prevent the patient's hands from being suspended in the air for a long time and moving up and down, thereby ensuring the precise control effect of the infusion pump.

[0007] Regarding this related technical patent, the inventor believes that: when the infusion pump in the device is installed and disassembled on the infusion pole, it is fixed by a screw and a buckle. In order to ensure the stability of the infusion pump, a large force is usually required when the screw is tightened and loosened when the infusion pole is tightened. When the patient needs to get up and move around, disassembly is time-consuming and laborious.

[0008] Therefore, the utility model provides an infusion pump with good stability and convenient mobility to solve the above problems. Utility Model Content

The contents mentioned in the following embodiments are all based on the drawings in the specification.

[0027] Various exemplary embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0028] Embodiment 1, by Figure 1-2 The utility model includes a pump body 1, a mounting groove 2 is provided at the front end of the pump body 1, mounting notches are provided at the upper and lower ends of the mounting groove 2, a pump door 3 is rotatably installed on the right side of the mounting groove 2, in order to avoid the problem of poor contact between the infusion tube and each sensor, an L-shaped slide groove 4 is fixedly connected in the mounting groove 2, a driving plate 5 is slidably installed up and down at the front end of the L-shaped slide groove 4, an inclined hole 6 is provided on the driving plate 5, a moving rod 7 is penetrated in the inclined hole 6 and slidably installed in the L-shaped slide groove 4, a push plate 8 is fixedly connected to the front end of the moving rod 7, and the front end of the push plate 8 The end is provided with an arc notch and a downwardly extruded protrusion, but it will not affect the multiple automatic sensors in the pump body 1. The right end of the drive plate 5 is threadedly connected with a drive rod 9 rotatably installed in the mounting groove 2. The pitch of the drive rod is relatively large. A passive gear 10 is coaxially fixedly installed at the lower end of the drive rod 9. The right side of the passive gear 10 is meshed with and rotatably installed in the mounting groove 2. A reversing gear 12 is coaxially fixedly installed on the upper end of the acceleration gear 11. A driving gear 13 meshing with the reversing gear 12 is coaxially fixedly installed on the rotating shaft of the pump door 3.

[0029] During specific use: first, the medical staff turns to open the pump door 3, then inserts the infusion tube into the installation notches on the upper and lower sides, and presses the infusion tube into each sensor and peristaltic structure 23 in turn, and then closes the pump door 3, while driving the driving gear 13 to engage with the reversing gear 12 to rotate, and then drives the acceleration gear 11 to engage with the passive gear 10 to rotate, and then drives the driving rod 9 to engage with the driving plate 5 to slide upward. Since the moving rod 7 is installed in the inclined hole 6, when the driving plate 5 slides upward, it drives the moving rod 7 to slide to the left in the horizontal groove on the lower side of the L-shaped groove 4, and at the same time drives the push plate 8 to move left to the front side of the infusion tube. After the push plate 8 contacts the infusion tube, the protrusion of the push plate 8 squeezes the infusion tube downward.

[0031] Specific use: When the patient needs to get up and move around, there is no need to remove the fixing device 15 from the infusion pole. At this time, the staff squeezes the two vertical plates close to each other, driving each positioning spring 19 to compress, and at the same time driving the two side clamping rods to disengage from the positioning holes 16 respectively. At this time, the pump body 1 is moved upward to make the plug plate 14 move upward and slide out of the fixing device 15. The disassembly and assembly is very simple and convenient, saving time and effort.

[0032] Embodiment 3, based on embodiment 1, Figure 1 It is given that a bubble sensor 20 is fixedly connected in the mounting groove 2, a positioning clip 21 is fixedly connected to the lower side of the bubble sensor 20, a pressure sensor 22 is fixedly connected to the lower side of the positioning clip 21, a peristaltic structure 23 is fixedly connected to the lower side of the pressure sensor 22, a liquid level sensor 24 is fixedly connected to the lower side of the peristaltic structure 23, and a liquid stop clip 25 is rotatably installed at the lower end of the liquid level sensor 24. The above-mentioned multiple sensors and peristaltic structures are inherent functions of the pump body, and multiple sensors are connected to the built-in controller of the main body, which will not be repeated here;

[0033] During specific use: after the infusion tube is inserted into the installation notches on the upper and lower sides, the infusion tube is positioned by the positioning clamp 21, and then the liquid stop clamp 25 is rotated to compress the infusion tube. The bubble sensor 20 is used to detect whether there are bubbles in the liquid. If bubbles are detected, the infusion pump will sound an alarm or stop infusion to ensure the safety of infusion. The pressure sensor 22 is often used to monitor the pressure of the infusion tube. It can sense the pressure changes in the infusion tube and adjust the flow rate of the infusion pump according to the set pressure range to maintain a suitable infusion speed. The peristaltic structure 23 is often used in the infusion pump to push the liquid in the infusion tube to accurately control the flow rate and dosage of the liquid. The liquid level sensor 24 is usually used to monitor the liquid level in the infusion container.

[0034] Embodiment 4, based on embodiment 2, Figure 3 The fixing device 15 includes a positioning buckle 26 and a positioning screw 27 threadedly mounted on the positioning buckle 26, a knob is fixedly mounted on one end of the positioning screw 27, and a rubber head is fixedly mounted on the other end located inside the positioning buckle 26;

[0035] When used specifically, the positioning buckle 26 is buckled onto the infusion pole, and then the knob is turned to drive the positioning screw 27 to rotate, so that the rubber head squeezes the infusion pole, and the infusion pump is fixedly installed on the infusion pole.

[0036] Embodiment 5, based on embodiment 1, Figure 1It is shown that a control panel 28 is provided at the front end of the pump body 1, and medical staff can control and operate the infusion pump through the control panel 28, set the infusion speed and dosage, monitor the infusion process, alarm and warning, infusion mode selection, data recording and review. The various functions of the control panel 28 are connected to the built-in controller. This is the prior art and will not be repeated here.

[0037] Working principle:

[0038] When the utility model is used, firstly, the positioning buckle 26 is buckled on the infusion rod, and then the knob is turned to drive the rubber head to squeeze the infusion rod, and the infusion pump is fixedly installed on the infusion rod, and then the pump door 3 is turned to open, and then the infusion tube is clamped into the installation notches on the upper and lower sides, and the infusion tube is pressed into each sensor and the peristaltic structure 23 in turn, and then the pump door 3 is closed, and at the same time, the driving gear 13 is driven to mesh with the reversing gear 12 to rotate, thereby driving the driving rod 9 to mesh with the driving plate 5 to slide upward, when the driving plate 5 slides upward, it drives the moving rod 7 to slide to the left in the horizontal slide groove on the lower side of the L-shaped slide groove 4, and at the same time drives the push plate 8 to move left to the front side of the infusion tube, and when the moving rod 7 moves to the leftmost side of the inclined hole 6, the driving plate 5 Continue to slide upward, synchronously drive the moving rod 7 to slide upward in the vertical slide groove of the L-shaped slide groove 4, thereby driving the push plate 8 to move upward. At this time, the push plate 8 pushes the infusion tube from bottom to top, so that the infusion tube is pressed tightly in each sensor and peristaltic structure 23. Not only can it avoid the problem of poor contact between the infusion tube and each sensor, but it also does not need to be pressed manually, and the operation is simple and convenient. In addition, due to the horizontal push-type pressing method, it can also avoid the problem of the infusion tube tilting between one pressing point and another pressing point. When the pump door 3 is completely closed, the push plate 8 just moves to the lower end of the upper mounting notch. Through the push plate 8 and the liquid stop clamp 25 on the lower side, the upper and lower sides of the infusion tube can be limited respectively, so as to avoid the infusion tube from shifting during use.

[0039] When the patient needs to get up and move around, there is no need to remove the fixing device 15 from the infusion pole. At this time, the staff squeezes the two vertical plates close to each other, causing each positioning spring 19 to be compressed, and at the same time, the two side clamping rods are respectively disengaged from the positioning holes 16. At this time, the pump body 1 is moved upward to make the plug plate 14 move downward and slide out of the fixing device 15. The disassembly and assembly is very simple and convenient, saving time and effort.

[0040] Compared with the prior art, the utility model has the following advantages:

[0041] 1. The device has an L-shaped slide, a driving plate, a moving rod and a push plate, which effectively avoids the problem of poor contact between the infusion tube and each sensor. When installing the infusion tube, the infusion tube is inserted into the installation notches on the upper and lower sides, and the infusion tube is pressed into each sensor and the peristaltic structure 23 in turn, and then the pump door is closed, and the driving plate is driven to slide upward at the same time, and the push plate is driven to move to the left to the front side of the infusion tube. When the moving rod moves to the leftmost side of the inclined hole, the driving plate continues to slide upward, and synchronously drives the push plate to move upward. At this time, the push plate pushes the infusion tube from bottom to top. Pushing upward horizontally can press the infusion tube tightly inside each sensor and the peristaltic structure 23, which can not only avoid the problem of poor contact between the infusion tube and each sensor, but also eliminate the need for manual pressing, and the operation is simple and convenient. In addition, due to the horizontal pushing method, the problem of the infusion tube tilting between one pressing point and another pressing point can be avoided. When the pump door is completely closed, the push plate just moves to the lower end of the upper mounting notch, and the push plate and the lower liquid stop clamp can limit the upper and lower sides of the infusion tube respectively to avoid displacement of the infusion tube during use.

[0042] 2. The device has a plug plate, a positioning hole, a positioning pin and a positioning spring, which achieves the purpose of facilitating the movement of the infusion pump. When the patient needs to get up and move around, there is no need to remove the fixing device from the infusion pole. At this time, the staff squeezes the two positioning pins close to each other and disengages them from the positioning holes, driving each positioning spring to compress. At this time, the pump body is moved upward to move the plug plate downward and slide out of the fixing device. The disassembly and assembly is very simple and convenient, saving time and effort.
