Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an infusion pump and an infusion system. Background Technology

[0002] Currently, syringe pumps typically use a clamp to hold the syringe outside the pump body, leaving the clamp and syringe exposed to the air. This design makes it easy for the syringe to be accidentally touched, and dust will fall on the clamp and syringe, which is unhygienic, inconvenient to clean, and affects the appearance. Summary of the Invention

[0003] In view of this, embodiments of the present invention provide an injection pump and injection system for preventing accidental contact of the syringe and reducing dust falling onto the clamp and syringe.

[0004] A first aspect of the present invention provides an injection pump for use with a syringe. The syringe includes a syringe body and a syringe piston. The injection pump includes a pump body, a clamp, and a pump gate. The injection pump is further provided with a drive mechanism, a transmission mechanism, a push-pull mechanism, and a processor. Under the control of the processor, the drive mechanism drives the push-pull mechanism to move linearly through the transmission mechanism. The syringe piston disposed on the push-pull mechanism moves synchronously with the push-pull mechanism.

[0005] The pump body has a receiving groove for accommodating the syringe body, and the side wall of the receiving groove has a mounting groove for installing and accommodating the clamp handle. The clamp handle is used to clamp the syringe body in the receiving groove.

[0006] The pump door is rotatably connected to the pump body, and the pump door is provided with a closed position and an open position; when the pump door is in the closed position, at least two sides of the pump door are connected to the pump body, and a receiving space is formed between the back of the pump door and the front of the pump body, and the clamp and at least a portion of the receiving groove are disposed in the receiving space, so that the part of the syringe body clamped by the clamp is disposed in the receiving space.

[0007] The syringe pump provided by this invention, when in use, places the syringe in the receiving groove inside the pump body, and fixes the syringe body in the receiving groove by the clamp handle; then, rotates the pump door to the closed position, so that the part of the syringe body held by the clamp handle is in the receiving space formed between the back of the pump door and the front of the pump body. On the one hand, this prevents dust from falling on the syringe body and the clamp handle, making it clean, hygienic, and aesthetically pleasing; on the other hand, it avoids accidental contact with the syringe. In addition, this invention has a mounting groove on the side wall of the receiving groove to accommodate the clamp handle, saving space.

[0008] A second aspect of the present invention provides an injection system, including an injection pump as described in any one of the above claims and a syringe used in conjunction with the injection pump;

[0009] The syringe pump includes a pump body, a clamp, a pump door, a drive mechanism, a transmission mechanism, a push-pull mechanism, a processor, a clamp shaft, a compression spring, a transmission slider, a pin, and a protective sleeve; the syringe includes a syringe body and a syringe piston; under the control of the processor, the drive mechanism drives the push-pull mechanism to move linearly through the transmission mechanism, and the syringe piston mounted on the push-pull mechanism moves synchronously with the push-pull mechanism;

[0010] The pump body has a receiving groove for accommodating the syringe body, and the side wall of the receiving groove has a mounting groove for installing and accommodating the clamp handle. The clamp handle is used to clamp the syringe body in the receiving groove.

[0011] The pump door is rotatably connected to the pump body, and the pump door is provided with a closed position and an open position; when the pump door is in the closed position, at least two sides of the pump door are connected to the pump body, and a receiving space is formed between the back of the pump door and the front of the pump body, and the clamp and at least a portion of the receiving groove are disposed in the receiving space, so that the part of the syringe body clamped by the clamp is disposed in the receiving space;

[0012] The clamp includes a connecting part, a clamping part, and a pressing part. The connecting part is connected to one end of the clamp shaft. The power transmission slider, the pin, and at least a portion of the clamp shaft are disposed within the pump body. The other end of the clamp shaft is rotatably connected within the pump body. The power transmission slider has a helical groove, and the pump body limits the rotation of the power transmission slider. The pin is connected to the clamp shaft and slides in cooperation with the helical groove. The compression spring is sleeved on the clamp shaft, and both ends of the compression spring abut against the power transmission slider and the connecting part, respectively. The pin slides along the helical groove, pushing the power transmission slider to move axially to compress or release the compression spring.

[0013] The spiral groove is closed at both ends, and a dead point is set at the end of the spiral groove away from the connecting part;

[0014] The protective sleeve is detachably fitted over the power transmission slider and covers the spiral groove; the clamp shaft has a mounting hole, at least a portion of the pin is installed in the mounting hole, and the protective sleeve covers both ends of the pin.

[0015] In this embodiment of the injection system, during use, pressing down on the pressing part of the clamp handle rotates the clamp handle shaft via the connecting part. The pin rotates with the clamp handle shaft, thereby pushing the power transmission slider to move axially towards the clamp handle, thus compressing the compression spring. When the space between the clamping part of the clamp handle and the receiving groove is sufficient to place the syringe body, the syringe body can be directly placed into the receiving groove, and the pressing part can be released. Alternatively, the pressing part can be pressed until the pin enters the dead point position of the spiral groove, and then the syringe body can be placed into the receiving groove. Then, the pressing part can be pried upward to disengage the pin from the dead point position of the spiral groove. Release the pressing part. At this time, under the action of the restoring force, the compression spring pushes the power transmission slider to move axially away from the clamp handle. The power transmission slider pushes the pin to rotate, and the pin drives the clamp handle shaft to rotate. In turn, through the connecting part, it drives the clamping part to rotate towards the receiving groove to clamp the syringe body. Finally, close the pump door, so that the part of the syringe body clamped by the clamp handle is in the receiving space formed between the back of the pump door and the front of the pump body. On the one hand, it avoids dust falling on the syringe body and clamp handle, making it clean, hygienic and aesthetically pleasing. On the other hand, it avoids accidental contact with the syringe.

[0016] This invention features a mounting groove on the side wall of the receiving groove to accommodate the clamping handle, saving space. Furthermore, this invention employs a compression spring, converting the compression force into a rotational circumferential force, improving the lifespan and reliability of the injection pump. The protective sleeve ensures the pin will not fall out, and the power transmission slider can operate stably. Attached Figure Description

Detailed Implementation

[0025] The following will refer to the appendices in the embodiments of this application. Figure 1-5 The technical solutions in the embodiments of this application are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0026] like Figure 1-3 As shown, the syringe pump provided in this embodiment of the invention includes a pump body 1, a clamp 2, and a pump door 3, wherein the syringe pump is used in conjunction with a syringe 4.

[0027] The syringe 4 includes a syringe body 401 and a syringe piston 402. Pushing the syringe piston 402 allows the liquid medicine inside the syringe body 401 to be output. The syringe pump also includes a drive mechanism, a transmission mechanism, a push-pull mechanism, and a processor. The processor is signal-connected to the drive mechanism, the drive mechanism is drive-connected to the transmission mechanism, and the transmission mechanism is drive-connected to the push-pull mechanism. The push-pull mechanism pushes the syringe piston 402 to move linearly. Specifically, under the control of the processor, the drive mechanism drives the push-pull mechanism to move linearly through the transmission mechanism, and the syringe piston 402, which is mounted on the push-pull mechanism, moves synchronously with the push-pull mechanism.

[0028] The drive mechanism can be any power device capable of providing power, such as an electric motor; the transmission mechanism can be any device capable of transmitting power, such as a gear set; the push-pull mechanism can be any device capable of pushing the syringe piston 402 to move. The syringe piston 402 can be fixedly connected to the push-pull mechanism, or it can be snapped together, etc.

[0029] The pump body 1 has a receiving groove 101 inside to accommodate the syringe body 401. The shape of the receiving groove 101 is not limited and can be any shape that can accommodate the syringe body 401, such as a regular shape like a V-shaped groove or an arc-shaped groove, or other irregular shapes. To facilitate processing and clamping of syringes 4 with different barrel diameters, a V-shaped groove is taken as an example for the receiving groove 101.

[0030] A mounting groove 102 is provided on the side wall of the receiving groove 101 for mounting and accommodating the clamp 2. The clamp 2 is used to clamp the syringe body 401 within the receiving groove 101. Specifically, the mounting groove 102 can be provided at the end of the side wall of the receiving groove 101, such as... Figure 2 As shown, the mounting groove 102 is formed at the right end of the side wall of the receiving groove 101 (facing the...). Figure 2 The orientation of the handle 2 is set for ease of description only and has no other specific meaning, making it easier for right-handed users to operate the clamp. It should be noted that the mounting slot 102 can also be located on the left end of the side wall of the receiving slot 101 (also facing...). Figure 2 (The orientation is set in the middle) to facilitate use by left-handed users. Understandably, the mounting slot 102 can also be located in the middle of the side wall of the receiving slot 101 or in any other location.

[0031] Pump door 3 is rotatably connected to pump body 1, and pump door 3 is provided with a door position and an open position. It should be noted that pump door 3 can also be connected to pump body 1 by snap-fit, etc.

[0032] When the pump door 3 is in the closed position, at least two sides of the pump door 3 are connected to the pump body 1, and a receiving space is formed between the back of the pump door 3 and the front of the pump body 1. The clamp 2 and at least a portion of the receiving groove 101 are disposed within the receiving space, so that the part of the syringe body 401 held by the clamp 2 is disposed within the receiving space. It should be noted that the back of the pump door 3 refers to the side of the pump door 3 facing the pump body 1 when the pump door 3 is in the closed position. The front of the pump body 1 refers to the side of the pump body 1 facing the pump door 3 when the pump door 3 is in the closed position. With the above-described syringe pump, when the pump door 3 is in the closed position, the part of the syringe body 401 held by the clamp 2 is disposed within the receiving space formed between the back of the pump door 3 and the front of the pump body 1. On the one hand, this prevents dust from falling onto the syringe body 401 and the clamp 2, ensuring cleanliness, hygiene, and aesthetics; on the other hand, it prevents accidental contact with the syringe 401.

[0033] In some embodiments, the syringe pump further includes a clamping shaft 6. The clamping handle 2 includes a connecting portion 201, a clamping portion 202, and a pressing portion 204. The clamping shaft 6 is rotatably connected to the connecting portion 201. Specifically, the clamping shaft 6 and the connecting portion 201 can be rotatably connected by a torsion spring, or the clamping shaft 6 and the connecting portion 201 can be threaded together, etc. The pressing portion 204 drives the connecting portion 201 to rotate relative to the clamping shaft 6, so that the clamping portion 202 is in a clamping position or a release position. When the clamping portion 202 is in the clamping position, it can clamp the syringe body 401 in the receiving groove 101; when the clamping portion 202 is in the release position, it can release the syringe body 401.

[0034] The clamp 2 can also be of other structures, such as Figure 4 and 5 As shown, the injection pump also includes a clamping shaft 6, and the clamping handle 2 further includes a connecting part 201, a clamping part 202, and a pressing part 204. The connecting part 201 is connected to one end of the clamping shaft 6, and the other end of the clamping shaft 6 is rotatably connected to the pump body 1. The pressing part 204 drives the connecting part 201 to rotate synchronously with the clamping shaft 6, so that the clamping part 202 is in the clamping position or the release position. Specifically, the connecting part 201, the clamping part 202, and the pressing part 204 are integrally molded. It should be noted that they can also be detachable. In order to facilitate processing and improve the connection strength of the connecting part 201, the clamping part 202, and the pressing part 204, the example is taken as an integrally molded connection of the connecting part 201, the clamping part 202, and the pressing part 204.

[0035] In some embodiments, a connecting hole is provided in the connecting part 201, and the clamping handle shaft 6 is inserted into the connecting hole to facilitate the disassembly and replacement of the clamping handle shaft 6 and the clamping handle 2. It should be noted that the clamping handle shaft 6 can also be integrally formed and connected to the connecting part 201, etc.

[0036] In some embodiments, the injection pump further includes a power transmission slider 8 and a pin 9. The power transmission slider 8, pin 9, and at least a portion of the clamping shaft 6 are disposed within the pump body 1. The power transmission slider 8 has a sliding groove, and the pump body 1 limits the rotation of the power transmission slider 8. Specifically, the power transmission slider 8 is cylindrical and has a limiting groove. The pump body 1 has a limiting protrusion that mates with the limiting groove, so that the power transmission slider 8 can only move along its axis. The pin 9 is connected to the clamping shaft 6 and slides with the sliding groove, pushing the clamping shaft 6 to rotate radially along the power transmission slider 8.

[0037] In some embodiments, the injection pump further includes a compression spring 7, which is sleeved on the clamping shaft 6, and its two ends abut against the power transmission slider 8 and the connecting part 201, respectively. It should be noted that the cross-section and trajectory of the sliding groove are not limited; for ease of manufacturing, a spiral groove 801 is taken as an example. The pin 9 slides along the spiral groove 801, pushing the power transmission slider 8 to move axially, thereby compressing or releasing the compression spring 7.

[0038] In some embodiments, the two ends of the sliding groove are closed to prevent the pin 9 from slipping out of the sliding groove. In order to keep the clamp 2 in the open state, the present invention discloses that a dead point is set at the end of the sliding groove away from the connecting part 201, so that the pin 9 can be locked at the dead point. When the clamp 2 needs to clamp the syringe body 401, the pressing part 204 of the clamp 2 is manually turned so that the connecting part 201 can drive the clamp shaft 6 to rotate, thereby driving the pin 9 to slide out from the dead point. Under the restoring force of the compression spring 7, the power transmission slider 8 is pushed to move axially to the side away from the clamp 2, thereby driving the pin 9 to rotate. The pin 9 drives the clamp shaft 6 to rotate, thereby driving the clamping part 202 to clamp the syringe body 401.

[0039] In some embodiments, the injection pump further includes a protective sleeve 10, which is detachably fitted over the power transmission slider 8 and covers the sliding groove. The clamping shaft 6 has a mounting hole, at least a portion of the pin 9 is installed in the mounting hole, and the protective sleeve 10 covers both ends of the pin 9 to prevent the pin 9 from falling off the clamping shaft 6.

[0040] Specifically, the power transmission slider 8 has an annular groove 802, and one end of the protective sleeve 10 is provided with a claw 1001 that can be engaged in the annular groove 802. The claw 1001 is integrally formed and connected with the protective sleeve 10. The claw 1001 is strip-shaped and has a certain elastic deformation capability. The claw 1001 is formed by opening a through groove at one end of the protective sleeve 10. The end of the claw 1001 is provided with a protrusion. In order to facilitate engagement with the protective sleeve 10, the protrusion is a conical protrusion.

[0041] It should be noted that the protective sleeve 10 can also be threaded to the power transmission slider 8 at one end. The protective sleeve 10 can also be connected to the power transmission slider 8 by screws or other forms of connection.

[0042] In some embodiments, an elastic buffer block 203 is provided on the clamping surface of the clamping part 202. When the clamping part 202 impacts the syringe body 401, it can buffer the impact and prevent the syringe body 401 from being damaged or deformed. It also has a buffering effect when impacting the hand. In addition, the elastic buffer block 203 increases the friction with the syringe body 401 to ensure reliable clamping.

[0043] Specifically, the present invention discloses that the elastic buffer block 203 is made of soft or hard rubber material and is arranged on the clamping surface along the direction of the vertical axis of the syringe 4, so as to achieve clamping of syringes 4 of different diameters.

[0044] Specifically, the clamping part 202 is an arc-shaped clamping part 202, which increases the contact area with the syringe body 401 and facilitates the clamping of the syringe 4. It should be noted that the shape of the clamping part 202 is not limited to arc shape, but can also be V-shaped or other shapes.

[0045] In some embodiments, a buffer protrusion 11 is provided at the connection between the clamping part 202 and the connecting part 201. On the one hand, the buffer protrusion 11 buffers the collision with the syringe 4; on the other hand, when the pressing part 204 is pried upward, it can also serve as a reminder that the syringe 4 is in place. In addition, the buffer protrusion 11 can also support the syringe 4.

[0046] Specifically, the cushioning protrusion 11 is a soft pad, or it can be made of other elastic materials.

[0047] In some embodiments, the pressing part 204 and the clamping part 202 are inclined at a preset angle so that a space is formed between the front of the pressing part 204 and the syringe 4, allowing a finger to be inserted, which facilitates pressing the pressing part 204. Here, the front of the pressing part 204 refers to the side of the pressing part 204 facing the syringe 4.

[0048] In some embodiments, a connecting plate 205 is connected between the pressing part 204 and the clamping part 202. The connection plate 205 improves the overall strength and rigidity of the clamping handle 2, thereby preventing deformation of the clamping handle 2.

[0049] In some embodiments, the pressing part 204 has a pressing groove or an anti-slip layer on its front side to prevent the finger from slipping when pressing the pressing part 204. The shape of the pressing groove is not limited and can be set to any shape. In order to facilitate finger pressing, the pressing groove fits the shape of the fingertip. Specifically, the anti-slip layer can be pasted on the front side of the pressing part 204 or it can be directly integrally formed and connected to the pressing part 204. The anti-slip layer is a plastic dotted layer or a patterned layer.

[0050] In some embodiments, the syringe pump further includes a clamp, one end of which is mounted on the pump body 1, and the other end of which is provided with a gripper for limiting the axial movement of the syringe barrel 4. Specifically, the clamp may be fixed to the end of the pump body 1 or fixed inside the pump body 1. The shape of the clamp and gripper is not limited.

[0051] In some embodiments, a notch 103 is provided at the bottom of the pump body 1, which allows fingers to enter the pump body 1 and pry open the pressing part 204. The notch 103 facilitates the operation of the clamp 2 when the pump door 3 is closed.

[0052] To further improve the operability of the clamp handle 2 when the pump door 3 is closed, a notch 104 is provided on the side of the pump body 1 to expose the clamp handle 2. The notch 104 allows fingers to be inserted into the pump body 1 to pry open the pressing part 204. The pressing part 204 can be lifted upwards or pressed downwards. Specifically, the shape of the notch 104 and the notch 103 is not limited.

[0053] In some embodiments, the syringe pump further includes a potentiometer and a potentiometer coupling 14. One end of the clamp shaft 6 is provided with a mounting groove 102, and the potentiometer coupling 14 is inserted into the mounting groove 102. The potentiometer is used to detect the angle of rotation of the potentiometer coupling 14 under the drive of the clamp shaft 6. By detecting the angle change of the clamp shaft 6, the feedback algorithm is adjusted. Different angles correspond to syringes 4 with different outer diameters, thereby determining the size and capacity of the syringe 4 in the database. It should be noted that the device for detecting the rotation angle of the clamp shaft 6 is not limited to a potentiometer and a potentiometer coupling 14; it can also be other devices capable of angle detection, such as an angular displacement sensor.

[0054] In some embodiments, the injection pump further includes a position detector 15, which is installed within the receiving groove 101 and positioned opposite the clamp 2, i.e., the clamp 2 and the position detector 15 are located within the same cross-section of the receiving groove 101, facilitating accurate detection by the position detector 15 of whether the syringe 4 is in position. Specifically, the position detector 15 can be a contact position detection sensor or a non-contact position detection sensor.

[0055] In some embodiments, an alarm light 16 is provided at the top of the pump body 1. When the injection pump malfunctions, the alarm light 16 illuminates. Simultaneously, an alarm can also be provided to sound an alarm when the injection pump malfunctions. Specifically, the injection pump malfunction may be due to the pump door 3 not being properly closed or the syringe 4 not being properly installed.

[0056] In some embodiments, the side wall of the receiving tank 101 is provided with a hanging member 17 for hanging the infusion tube of the syringe 4 output end, which facilitates the hanging of the infusion tube.

[0057] In some embodiments, the side wall of the receiving groove 101 is provided with a first clearance groove 105 that communicates with the receiving groove 101. The first clearance groove 105 can provide clearance space for the side of the clamping part 202. On the one hand, it facilitates the rotation of the clamping handle 2 into position, and on the other hand, it avoids the clamping handle 2 occupying extra space. The shape of the first clearance groove 105 is not limited, and any first clearance groove 105 that can provide clearance space for the side of the clamping part 202 is within the protection scope of this invention.

[0058] In some embodiments, a second clearance groove 301 is provided on the back side of the pump door 3 to avoid the clamping part 202. It should be noted that the back side of the pump door 3 refers to the side of the pump door 3 facing the pump body 1. The provision of the second clearance groove 301 reduces the overall volume of the injection pump while allowing the clamping handle 2 to rotate into position. The shape of the second clearance groove 301 is not limited and can be square or circular, etc.

[0059] In some embodiments, the outer side of the bottom end of the pump body 1 extends beyond the outer side of the top end of the pump body 1 by a predetermined length, so as to provide sufficient installation space for the clamp 2. It should be noted that the outer side of the bottom end of the pump body 1 refers to the side of the bottom end of the pump body 1 facing the pump door 3, and the outer side of the top end of the pump body 1 refers to the side of the top end of the pump body 1 facing the pump door 3.

[0060] In some embodiments, the bottom end of the pump door 3 is hinged to the outer surface of the bottom end of the pump body 1, and when the pump door 3 is in the closed position, the top end of the pump door 3 is engaged with the top end of the pump body 1 or connected by attraction through magnet 13. Specifically, magnets 13 can be provided on the top end of the pump door 3 and the top end of the pump body 1 respectively. The shape of the magnets 13 is not limited. When the pump door 3 is closed, the magnets 13 on the pump door 3 and the magnets 13 on the pump body 1 are attracted to each other. Alternatively, an iron block can be installed on either the pump door 3 or the pump body 1, and correspondingly, magnets 13 can be installed on either the pump body 1 or the pump door 3. The pump door 3 is closed by the attraction of the magnets 13 to the iron block. Alternatively, a hook can be provided on the pump door 3 and a slot can be provided on the pump body 1. The pump door 3 is closed by the engagement of the hook and the slot. The connection between the pump door 3 and the pump body 1 can also be in other forms.

[0061] Specifically, the top of the pump door 3 is arc-shaped and extends smoothly to the outer side of the top of the pump body 1. On the one hand, it is aesthetically pleasing, and on the other hand, it reduces the overall space occupied by the pump body 1.

[0062] In some embodiments, the pump door 3 includes a transparent panel portion 302 and a door body portion 303. The transparent panel portion 302 is mounted on the door body portion 303 and is located at the top of the door body portion 303. At least a portion of the receiving groove 101 disposed in the receiving space is visible through the transparent panel, or the syringe 4 body disposed on at least a portion of the receiving groove 101 disposed in the receiving space is visible through the transparent panel, making it convenient for the user to observe the syringe 4 and other conditions inside the pump body 1.

[0063] Specifically, the transparent panel 302 can be made of transparent glass or transparent plastic. The door body 303 can be made of any material, and can be made of transparent, opaque, or semi-transparent material.

[0064] In some embodiments, the pump door 3 also includes a screen cover 304 disposed on the outside of the door body 303, and a physical button 305 disposed on the screen cover 304, including a start button to turn on the injection pump and a stop button to turn off the injection pump.

[0065] It should be noted that virtual buttons can also be set on the screen cover 304 to replace physical buttons 305, or both physical buttons 305 and virtual buttons can be set at the same time, so that the injection pump can still be controlled even when one of the physical buttons 305 or virtual buttons fails. Voice control can also be set to control the injection pump.

[0066] In some embodiments, the present invention discloses that the pump door 3 and the clamp handle 2 can also be linked, that is: when the pump door 3 is open, the clamp handle 2 releases the syringe 4; when the pump door 3 is closed, the clamp handle 2 clamps the syringe 4. Specifically, the pump door 3 and the clamp handle 2 can be linked by a linkage controller or by mechanical linkage control. For example, the pump door 3 and the clamp handle 2 are connected by a hinge. When the pump door 3 is open, the clamp handle 2 rotates away from the syringe 4 under the action of the hinge, thereby releasing the syringe 4; when the pump door 3 is closed, the clamp handle 2 returns to the position of clamping the syringe 4 under the action of the compression spring 7 or torsion spring, etc.

[0067] In some embodiments, the clamp 2 may also be connected to the pump body 1 in other ways. For example, the syringe pump also includes a tension spring in an extended state, with one end of the tension spring connected to the pump body 1 and the other end of the tension spring connected to the clamp 2. By pulling the clamp 2 away from the syringe 4, the clamp 2 releases the syringe 4; by releasing the clamp 2, the clamp 2 clamps the syringe 4 under the action of the spring's restoring force.

[0068] This invention also provides an injection system, including the above-described injection pump and a syringe 4 used in conjunction with the injection pump.

[0069] Specifically, the syringe pump includes a pump body 1, a handle 2, a pump door 3, a drive mechanism, a transmission mechanism, a push-pull mechanism, a processor, a handle shaft 6, a compression spring 7, a transmission slider, a pin 9, and a protective sleeve 10. The syringe 4 includes a syringe body 401 and a syringe piston 402. The syringe piston 402 slides within the syringe body 401 to expel the liquid medication from the syringe body 401. The output of liquid medication from the syringe 4 is achieved through the combined action of the drive mechanism, the transmission mechanism, the push-pull mechanism, and the processor. Specifically, under the control of the processor, the drive mechanism drives the push-pull mechanism to move linearly via the transmission mechanism, and the syringe piston 402, mounted on the push-pull mechanism, moves synchronously with the push-pull mechanism.

[0070] The pump body 1 has a receiving groove 101 for receiving the syringe body 401. The side wall of the receiving groove 101 has a mounting groove 102 for installing and receiving the clamp 2. The clamp 2 is used to clamp the syringe body 401 in the receiving groove 101.

[0071] Pump door 3 is rotatably connected to pump body 1, and pump door 3 is provided with a closed position and an open position. Specifically, pump door 3 is hinged to pump body 1, and the top of pump door 3 is attracted to the top of pump body 1 by magnet 13 to achieve the closing of pump door 3. When pump door 3 is in the closed position, at least two sides of pump door 3 are connected to pump body 1, and a receiving space is formed between the back of pump door 3 and the front of pump body 1. Clamp handle 2 and at least a portion of receiving groove 101 are disposed in receiving space, so that the part of syringe body 401 clamped by clamp handle 2 is disposed in receiving space, preventing dust from falling on syringe body 401 and preventing accidental contact with syringe 4.

[0072] The clamp 2 includes a connecting part 201, a clamping part 202, and a pressing part 204. The connecting part 201 is connected to one end of the clamp shaft 6, and the other end of the clamp shaft 6 is rotatably connected to the pump body 1. The pressing part 204 drives the connecting part 201 and the clamp shaft 6 to rotate synchronously, so that the clamping part 202 is in the clamping position or the release position. When the clamping part 202 is in the clamping position, it can clamp the syringe 4. When the clamping part 202 is in the release position, it can release the syringe 4.

[0073] The power transmission slider 8, pin 9, and at least a portion of the clamping shaft 6 are disposed within the pump body 1. The power transmission slider 8 has a spiral groove 801, and the pump body 1 limits the rotation of the power transmission slider 8. The pin 9 is connected to the clamping shaft 6, and the pin 9 slides in engagement with the spiral groove 801. The compression spring 7 is sleeved on the clamping shaft 6, and both ends of the compression spring 7 abut against the power transmission slider 8 and the connecting part 201, respectively. The pin 9 slides along the spiral groove 801, pushing the power transmission slider 8 to move axially, thereby compressing or releasing the compression spring 7.

[0074] The sliding groove is closed at both ends to prevent the pin 9 from slipping. A dead point is set at the end of the sliding groove away from the connecting part 201. When the pin 9 is placed at the dead point, the clamp 2 can be kept in the released position for any time.

[0075] The protective sleeve 10 is detachably fitted over the power transmission slider 8 and covers the sliding groove. The clamp shaft 6 has a mounting hole, at least part of the pin 9 is installed in the mounting hole, and the protective sleeve 10 covers both ends of the pin 9.

[0076] This invention ensures that the portion of the syringe body 401 held by the clamp 2 is within the receiving space. This prevents dust from settling on the syringe body 401 and clamp 2, maintaining cleanliness and aesthetics. It also prevents accidental contact with the syringe 4. An mounting groove 102 is provided on the side wall of the receiving groove 101 to accommodate the clamp 2, saving space. Furthermore, this invention employs a compression spring 7, converting the compression force of the spring 7 into a rotational circumferential force, improving the lifespan and reliability of the syringe pump. The protective sleeve 10 ensures that the pin 9 will not fall out, and the power transmission slider 8 can operate stably.
