The syringe pump 100 described herein is used in conjunction with a syringe 200 containing a medical fluid to achieve high precision, smooth, pulsation-free fluid delivery.

Referring to fig. 1 to 4, an embodiment of the present application provides a syringe pump 100, where the syringe pump 100 includes: a push-pull cassette assembly 120, a pump body 110, a holding space 111a, a screen mounting part 130, and a syringe holding part 140. The pump main body 110 includes a housing 111, a driving mechanism (not shown), and a connecting shaft 112, the housing 111 having a receiving chamber (not shown) in which the driving mechanism is disposed, one end of the connecting shaft 112 being drivingly connected to the driving mechanism, and the other end of the connecting shaft 112 extending from the right side of the housing 111 to the outside of the housing 111 and being connected to the push-pull box assembly 120. The push-pull box assembly 120 is used for being connected with a piston 203 of the injector 200, the connecting shaft 112 can drive the push-pull box assembly 120 to move linearly under the driving of the driving mechanism, and the push-pull box assembly 120 pushes the piston 203 to move in a needle cylinder 201 of the injector, so that high-precision, stable and pulsation-free liquid transmission is realized. In one embodiment, when the push-pull box assembly 120 pushes the piston 203 to move to the direction of the liquid outlet end of the syringe 201 to the limit position, a gap is formed between the push-pull box assembly 120 and the holder 141, thereby preventing the push-pull box assembly 120 and the holder 141 from interfering with each other.

The clamping space 111a is provided at one side of the pump body 110 and is located at the left side of the push-pull cassette assembly 120. The clamping space 111a includes a clamping passage 111c, and a clamp holder installation region 111b located at one side of the clamping passage 111c and communicating with the clamping passage 111 c. The clip channel 111c is for receiving the syringe 200 and the clip handle mounting area 111b is for mounting the clip handle 141.

The screen mounting portion 130 blocks the clamping space 111a and at least partially avoids the clamping area 111b, that is, the screen mounting portion 130 avoids a partial area of the clamping area 111b, or avoids the entire clamping area 111 b. The screen mounting part 130 includes a frame body 131 and a screen assembly 132. The frame body 131 is connected to the pump main body 110, a surface of the frame body 131 facing away from the pump main body 110 is a front surface of the frame body 131, the screen assembly 132 is disposed on the frame body 131, and a display area of the screen assembly 132 is located on the front surface of the frame body 131.

Syringe flange retainer 142 cooperates with clamp handle 141 to secure syringe 201 of injector 200. Specifically, when the injector 200 is clamped in the clamping space 111a, the syringe flange positioning member 142 positions the flange 202 of the injector 200, and the clamp holder 141 clamps the syringe 201 of the injector 200, thereby enabling the injector 200 to be fixed in the clamping space 111 a.

Referring to fig. 1 and 2, in one embodiment, the frame 131 may be a pump door movably connected to the pump body 110 to block or avoid at least a partial region of the clamping space 111 a. Specifically, the pump door can rotate or translate relative to the pump body 110 to effect opening or closing of the pump door. That is, the pump door may be opened when the syringe 200 is to be taken or placed, and may be closed when the syringe 200 is not to be taken or placed.

Referring to fig. 4, in one embodiment, the frame body 131 is fixedly connected to the pump body 110, a second avoiding opening 111f communicating with the clamping space 111a is formed between the frame body 131 and the pump body 110, and the syringe 200 is inserted into the clamping space 111a or removed from the clamping space 111a through the second avoiding opening 111 f.

In one embodiment, the syringe pump 100 further comprises a controller, and the screen assembly 132 is a touch screen assembly, which includes a display control chip, a display screen, a touch control chip and a touch screen, wherein the display control chip is integrated with the emitting end and the receiving end of the display screen. The front surface of the frame body 131 has a light transmission region, and the touch screen and the display screen are stacked in the frame body 131 and located at the light transmission region, that is, the display region of the screen assembly is located at the light transmission region of the frame body 131.

In the related art, there are generally a plurality of display control chips for transmitting and receiving signals, but the display control chips occupy a large space in the frame body 131, thereby causing the display area of the screen assembly 132 to be compressed.

After the transmitting terminal and the receiving terminal of the display screen are integrated on the display control chip, the number of the display control chips can be reduced, and thus, the assembly space occupied by the display control chips in the frame body 131 can be reduced, and thus, the display area of the screen assembly 132 can be increased as much as possible.

In one embodiment, the screen assembly 132 is bonded to the frame 131 by an adhesive, which may be an adhesive with characteristics of easy cleaning, corrosion resistance, etc., so as to meet high cleaning and disinfection requirements of medical equipment. Specifically, the adhesive may be a thermal reaction adhesive, and meanwhile, the frame body 131 may be provided with an adhesive dispensing groove, the adhesive dispensing groove is located on the periphery of the screen assembly 132, after the screen assembly 132 is mounted on the frame body 131, the thermal reaction adhesive is injected into the adhesive dispensing groove, and after the thermal reaction adhesive is cured, an elastic soft adhesive is formed, so that the screen assembly 132 and the frame body 131 can be bonded together. The thermal reaction glue is convenient for fixing the screen assembly 132, and can also play a role in buffering, protecting and preventing water for the screen assembly 132.

In one embodiment, the width of the display area of the screen assembly 132 is greater than or equal to 70% of the front width of the frame body 131. Since the syringe pump 100 is generally wider than it is tall, the space in the width direction of the syringe pump 100 can be fully utilized, so that the screen assembly 132 can be arranged in a long bar shape, thereby ensuring that the display area can display as much information as possible for the operator to view.

In other embodiments, the height of the display area of the screen element 132 may be greater than or equal to 60% of the height of the front surface of the frame body 131, the area of the display area may be greater than or equal to the front surface area 2/3 of the frame body 131, or, referring to fig. 8, the display area may cover the front surface of the frame body 131, which is equivalent to the display screen of the screen element 132 being a full screen.

Referring to fig. 2, 4, 5 and 8, in an embodiment, the injection pump 100 further includes a solid key 160, the solid key 160 may be disposed on the frame body 131, specifically, referring to fig. 2, 4 and 5, the solid key 160 may be disposed on the front surface of the frame body 131, referring to fig. 8, the solid key 160 may also be disposed on the side surface of the frame body 131. In other embodiments, the physical keys 160 may also be disposed on the housing 111. In other embodiments, the screen assembly 132 includes a transparent cover plate, the front surface of the frame body 131 further has a mounting area, the mounting area is located at one side of the display area, the physical keys 160 are disposed in the mounting area, the transparent cover plate covers the mounting area and the display area, that is, the display screen and the touch screen are disposed in the display area, the physical keys 160 are disposed in the mounting area, and the display screen, the touch screen and the physical keys 160 are all located at the inner side of the transparent cover plate.

The entity keys 160 may be one or more of a power key, an emergency stop key, a main menu key, a screen unlock key, a pump door unlock key, and the like, and when the number of the entity keys 160 is plural, the plural entity keys 160 may be all disposed on the housing 111, or all disposed on the frame body 131, or a part of the plural entity keys 160 may be disposed on the housing 111 and another part may be disposed on the frame body 131, or a part of the plural entity keys 160 may be disposed in the installation area and another part of the plural entity keys 160 may be disposed on the housing 111 and/or the frame body 131.

Referring to fig. 2, 5 to 8, in one embodiment, the syringe pump 100 further includes a warning lamp 170, and the warning lamp 170 is disposed on the housing 111 or the frame body 131. In one embodiment, the warning light 170 may also be disposed in the mounting area.

The grip 141 is mainly used to grip or release the syringe 201 of the injector 200, and the grip 141 may have various structural forms. Referring to fig. 1 to 4, in one embodiment, the clamp holder mounting region 111b is in communication with the outside so that an operator can rotate the clamp holder 141. Referring to fig. 3, the grip 141 is rotated relative to the pump body 110 to grip or release the cylinder 201 of the syringe 200. Specifically, when the operator rotates the grip 141 in a direction to approach the syringe 200, the grip 141 grips the syringe 200, and when the operator rotates the grip 141 in a direction to get away from the syringe 200, the grip 141 releases the gripped syringe 200.

Further, in one embodiment, the syringe clamping part further includes a clamp shaft, the clamp handle 141 includes a clamping member and a pressing member, one end of the clamp shaft is connected to the clamp handle 141, and the other end of the clamp shaft is rotatably connected to the inside of the pump body 110, and the clamp handle 141 and the clamp shaft are rotated in synchronization by pressing the pressing member to clamp or release the syringe 201 of the syringe 200.

In one embodiment, the syringe clamping portion 140 further comprises a torsion spring, one end of which is connected to the clamp handle 141 and the other end of which is connected to the pump body 110. The torsion spring rotates the grip 141 relative to the pump body 110 to grip or release the syringe 201 of the syringe 200.

In one embodiment, the clamp handle shaft may also be a damping shaft that may reduce the rotational speed to prevent the clamp handle 141 from rotating too fast and breaking the syringe 200.

Referring to fig. 5, in one embodiment, the screen mounting portion 130 is retracted from the clamping bar mounting area 111b, the clamping bar 141 is translated in a direction perpendicular to the clamping channel 111c (i.e., a direction indicated by a double arrow a in fig. 5) to clamp or release the syringe 201 of the syringe 200, i.e., the clamping bar 141 is in a pull-type, the clamping bar 141 can be pulled out from the side of the pump body 110 where the screen mounting portion 130 is disposed, and after the syringe 200 is placed in the clamping channel 111c, the clamping bar 141 can be pushed in a reverse direction to clamp the syringe 201 of the syringe 200.

The clamp holder 141 can be drawn in various ways, for example, referring to fig. 6, in one embodiment the injector clamp further includes a guide rod 144 and a linkage member. The linkage assembly includes a first linkage member 146 and a second linkage member (not shown). The second linkage member is disposed in the accommodating cavity, one end of the guide rod 144 is connected to the clamp handle 141, the other end of the guide rod 144 is connected to the first linkage member 146, and the first linkage member 146 is linked with the second linkage member, so that the clamp handle 141 can translate in a direction perpendicular to the clamping channel 111 c. The first linkage member 146 and the second linkage member may be a combination of a gear and a gear, a combination of a gear and a rack, or other linkage combinations as long as the clamp holder 141 can be translated in a direction perpendicular to the clamping channel 111 c.

Further, for the above-mentioned pull-type clamp holder 141, the syringe flange positioning element 142 may also be configured to be interlocked with the clamp holder 141, for example, referring to fig. 5 and 6, in an embodiment, the syringe flange positioning element 142 includes a pressing plate 1421 and a connecting rod 1422, the pressing plate 1421 is disposed outside the housing 111 and is located at a side of the housing 111 close to the push-pull box assembly 120, one end of the connecting rod 1422 is connected to the pressing plate 1421, and the other end of the connecting rod 1422 extends into the accommodating cavity. The syringe clamping portion 140 further includes a return spring 143 disposed in the accommodating cavity, and the return spring 143 is sleeved on one end of the connecting rod 1422 in the accommodating cavity. The syringe clamping portion 140 further includes a swing link 145 disposed in the receiving chamber, the guide rod 144 is rotatably connected to the first link 146, and the swing link 145 is disposed on the guide rod 144. When the injector 200 needs to be clamped, an operator pulls the clamp handle 141 outward, the clamp handle 141 translates to a preset position in a direction away from the clamping channel 111c, and then rotates in a direction (i.e., a direction indicated by an arrow B in fig. 6) in which the pressure plate 1421 is located, the guide rod 144 drives the swing rod 145 to push the connecting rod 1422, the return spring 143 elastically deforms, and the pressure plate 1421 translates in a direction away from the housing 111, so that a flange clamping space 111g is formed between the pressure plate 1421 and the housing 111. When the syringe 200 is placed in the clamping passage 111c, a part of the flange 202 of the syringe 200 extends into the flange clamping space 111g, and then the clamping handle 141 is rotated in the opposite direction, the swing rod 145 is separated from the connecting rod 1422, and the return spring 143 drives the pressing plate 1421 to press the flange 202.

In other embodiments, the syringe flange positioning element 142 may not be linked with the clamping handle 141, for example, referring to fig. 1 to 4, in one embodiment, the syringe flange positioning element 142 may also be an elastic clip fixedly connected with the sidewall of the housing 111, and when the syringe 200 needs to be clamped, the flange 202 of the syringe 200 only needs to be pushed into the gap between the elastic clip and the sidewall of the housing 111. In other embodiments, the resilient clip may also be secured in the clamping space 111 a. In another embodiment, the syringe flange positioning element 142 may also be a clip that cannot be elastically deformed, the clip is disposed on the sidewall of the housing 111, and a flange positioning gap is formed between the clip and the sidewall of the housing 111, when the syringe 200 needs to be clamped, the flange 202 only needs to be pushed into the flange positioning gap formed between the clip and the sidewall of the housing 111. In another embodiment, a portion of the sidewall of the housing 111 is recessed to form a positioning groove, which is the syringe flange positioning element 142. In addition, the elastic clip, the common clip and the positioning groove may be used for the pull-type grip 141, and may also be used for the non-pull-type grip 141.

In an embodiment, the pulling manner of the clamp holder 141 may be that an elastic member is disposed in the syringe pump 100, one end of the elastic member is connected to the clamp holder 141, and the other end of the elastic member is fixedly connected to the pump body 110, when the syringe 200 needs to be clamped, an operator pulls the clamp holder 141 in a direction away from the clamping channel, the clamp holder 141 translates in a direction away from the clamping channel, the elastic member elastically deforms, and after the syringe 200 is inserted into the clamping channel 111c, the elastic member is returned to the clamping state, so that the clamp holder 141 can clamp the syringe 200.

Further, referring to fig. 7, the clamping handle 141 of the present embodiment has a clamping groove 141a, one side of the clamping groove 141a has a first opening 141b communicated with the clamping groove 141a, and when the clamping handle 141 is in the clamping state, the first opening 141b faces the clamping passage 111c, which is equivalent to a portion of the structure of the syringe 200 extending into the clamping groove 141a from the first opening 141 b. The clip groove 141a is gradually narrowed from the open end provided with the first opening 141b toward the other end away from the open end, that is, the clip groove 141a has a substantially V-shape, thereby facilitating gripping of syringes 200 having different diameters.

In addition, referring to fig. 7, for the clamping handle 141 of the above two structural forms, when the frame body 131 is a pump door, the side of the clamping channel 111c close to the screen mounting portion 130 further has a second opening 111e communicated with the clamping channel 111c, and the syringe 200 is placed into the clamping channel 111c through the second opening 111e or taken out from the clamping channel 111 c. In an embodiment, the clamping channel 111c may also gradually shrink from the open end provided with the second opening 111e to the other end away from the open end of the second opening 111e, i.e. the clamping channel 111c also has a substantially V-shaped cross section, thereby better fitting with the clamping handle 141 to fix syringes 200 with different diameters.

In other embodiments, the top of the clamping space 111a may also have a first escape opening communicating with the clamp holder mounting region 111b, the clamp holder mounting region 111b still communicating with the clamping channel 111c from one side of the clamping channel 111 c. The grip 141 is translated from the first escape opening 111d in a direction perpendicular to the grip passage 111c to grip or release the cylinder 201 of the syringe 200. That is, the pull-type grip 141 may be changed to pull the grip 141 from the top of the grip passage 111c to the outside through the first escape opening 111d, and after the syringe 200 is inserted into the grip passage 111c, the grip 141 is pushed in the opposite direction so that the grip 141 grips the syringe 200.

It should be noted that, for the syringe pump 100 in which the screen mounting portion 130 is disposed away from the entire clip handle 141, in order to ensure that the display area of the screen assembly 132 can be made as large as possible, the width dimension of the clip handle 141 cannot be too large to avoid reducing the width dimension of the screen mounting portion 130, and at the same time, the width dimension of the clip handle 141 cannot be too small, and if the width dimension of the clip handle 141 is too small, the clip handle 141 cannot clamp the syringe 200, preferably, the width dimension of the clip handle 141 may be 20-30mm, and more preferably, the width dimension of the clip handle 141 may be about 25 mm.

In one embodiment, the syringe clamping portion 140 further comprises a resilient cushion disposed on the clamping surface of the clamp handle 141 to prevent the clamp handle 141 from damaging the syringe 200 when clamping the syringe 200.

In one embodiment, the syringe clamping portion 140 may further include a potentiometer and a shaft. The clamp handle is connected with the rotating shaft, the rotating shaft is connected with the potentiometer, and the potentiometer is used for detecting the rotating angle of the rotating shaft. Since different rotation angles of the rotation shaft may correspond to the syringes 200 having different diameters, the size and capacity of the syringes 200 may be determined by detecting the rotation angle of the rotation shaft.

Referring to fig. 3, in one embodiment, the syringe pump 100 may further include a position detecting device 150, and the position detecting device 150 is disposed in the clamping space 111 a.
