In the conventional syringe pump/infusion pump, a fastening ring is generally erected on the surface of a housing, and the syringe pump/infusion pump is directly fixed on a fixing rod by using the fastening ring when the syringe pump/infusion pump is used. And because the fastening ring is vertically arranged on the shell, when the injection pump/infusion pump is not required to be fixed on the fixed rod, the whole required space is enlarged when the injection pump/infusion pump is placed because the length of the fastening ring protruding from the surface of the shell is too long, and the storage of equipment is not facilitated, namely, the problem that the whole occupied space is overlarge because the fastening device is unreasonably arranged in the existing injection pump/infusion pump is solved.

To solve the above problems, the present utility model proposes a syringe pump/infusion pump.

In this embodiment, the syringe pump/infusion pump includes a pump body (not shown) and a fastening device 10. The pump body has a housing, the fastening device 10 includes a fastening clip 200, the fastening clip 200 is connected to the housing, the fastening clip 200 has a first state standing on the housing and a second state lying on the housing, and the fastening clip 200 is switchable between the first state and the second state; wherein the fastening clip 200 is in a first state, and is operable to secure the pump body to a securing rod.

When the fastening clip 200 is required to be used to fix the pump body to the fixing rod, the fastening clip 200 is vertically arranged on the housing, namely, the fastening clip 200 is placed in the first state, and when the injection pump/infusion pump is idle, the fastening clip 200 is horizontally arranged on the housing, namely, the fastening clip 200 is placed in the second state, the length of the fastening clip 200 protruding from the surface of the housing is greatly reduced, and the influence of the fastening device 10 on the size of the space occupied by the whole injection pump/infusion pump device is reduced.

The fastening clip 200 is connected to the housing in a magnetic connection, a detachable connection, or the like, so as to switch between the first state and the second state. For example, magnets are arranged on the bottom surface and the side surfaces of the fastening clip 200, iron sheets are arranged on the housing, when the bottom surface of the fastening clip 200 is connected with the housing by magnetic force, the fastening clip 200 stands on the housing, and when the side surface of the fastening clip 200 is connected with the housing by magnetic force, the fastening clip 200 is horizontally arranged on the housing. When a detachable connection, such as a bolt 150, is used, the fastening clip 200 stands on the housing when the bottom surface of the fastening clip 200 is connected to the housing by the bolt 150, and the fastening clip 200 stands on the housing when the bolt 150 is detached and reinstalled so that the side surface of the fastening clip 200 is connected to the housing by the bolt 150.

Referring to fig. 1 and 6, in view of the small area of the bottom surface of the fastening clip 200, the fastening clip 200 cannot be stably erected on the housing by means of magnetic connection, and the required magnetic force is strong to ensure the stability of the connection between the fastening clip 200 and the housing, so that the operation is not easy when the connection surface between the fastening clip 200 and the housing is switched. If the bolts 150 are used for connection, repeated disassembly and assembly operations are complicated, and the operation is inconvenient. In view of this, in an embodiment, the fastening device 10 further includes a base 100, the base 100 is connected to the housing, the fastening clip 200 is connected to the base 100, and the fastening clip 200 can be turned relative to the base 100.

Specifically, the base 100 is provided with a connection hole 140, the housing is provided with a corresponding second connection hole 140, the connection hole 140 and the second connection hole 140 are penetrated by a bolt 150, and the base 100 is fixed to the housing by using a nut 160. When the fixing frame is a cross bar or a vertical bar, the fastening clip 200 needs to be adjusted to be connected with the fixing frame, so that the whole fastening device 10 can rotate around the bolt 150, and when the placing direction of the fixing rod is changed, the fastening device 10 can be rotated to keep the angle of the fastening clip 200 matched with the direction of the fixing rod, thereby avoiding the complicated step of disassembling the fastening device 10. Because the fastening clip 200 is connected to the base 100 and can be turned over relative to the base 100, when the state of the fastening clip 200 needs to be switched, only the fastening clip 200 needs to be turned over, thereby simplifying the switching operation.

Further, when the fastening clip 200 is in the first state and is connected to the fixing rod, if the fastening clip 200 is also in a reversible state with respect to the base 100, the fixed connection between the pump body and the fixing rod cannot be ensured, so that the fastening clip 200 cannot be further turned over, i.e., locked to the base 100 when the fastening clip 200 is further required to be erected on the base 100.

Specifically, a clamping protrusion may be disposed on the base 100, a corresponding clamping groove is disposed on a side surface of the fastening clip 200, when the fastening clip 200 rotates from the second state to the first state, the clamping protrusion is clamped in the clamping groove, the fastening clip 200 is locked on the base 100, and when an external force is applied to disengage the clamping protrusion from the clamping groove, the fastening clip 200 resumes the rotatable state again.

Referring to fig. 2 to 9, considering that the syringe pump/infusion pump is fixed on the fixing rod, if the fastening clip 200 and the base 100 are locked by the locking protrusion and the locking groove, the locking protrusion receives a larger shearing force, and the locking protrusion is easy to break. Therefore, in another embodiment, the fastening device 10 further includes a fixing base 300 and a button 400, the fixing base 300 is mounted on the base 100, a first groove 310 is formed in a top surface of the fixing base 300, a hole 320 is formed in a side surface of the fixing base 300, the first groove 310 is communicated with the hole 320, a avoiding groove 230 is formed in a side, close to the fixing base 300, of the fastening clip 200, a protrusion 240 is formed in an inner wall of the avoiding groove 230, the button 400 can be inserted into the hole 320 to block the first groove 310, when the fastening clip 200 is in the first state, the protrusion 240 abuts against the button 400, and the fastening clip 200 is fixed on the base 100.

When the button 400 is not inserted into the hole 320 or the first groove 310, the first groove 310 is in a clear state, and when the fastening clip 200 is turned relative to the base 100, the avoiding groove 230 is avoided from the fixing base 300, and the protrusion 240 freely passes through the first groove 310. When the button 400 is inserted into the hole 320 and blocks the first recess 310, the fastening clip 200 cannot be freely switched between the first state and the second state because the button 400 blocks the protrusion 240 from passing through the first recess 310. At this time, since the bottom surface of the fastening clip 200 abuts against the top surface of the base 100, the protrusion 240 abuts against the button 400 only when the fastening clip 200 is in the first state, so that the fastening clip 200 cannot be turned over relative to the base 100, and the fastening clip 200 is fixed to the base 100. When the fastening clip 200 needs to be switched from the first state to the second state, the fastening clip 200 can be turned over to the state of lying on the base 100 only by withdrawing the button 400 from the hole 320 to restore the first groove 310 to be clear.

Considering that the button 400 is easy to lose during the process of inserting and withdrawing the hole 320, which affects the normal use of the fastening device 10, further, in an embodiment, a spring 500 is abutted between the bottom of the hole 320 and the button 400, the button 400 is provided with a second groove 410 with the same opening direction as the first groove 310, the side surface of the second groove 410 is provided with a limit protrusion 420, when the spring 500 is in a natural state, the limit protrusion 420 is located in the first groove 310, and when the spring 500 is compressed, the limit protrusion 420 moves towards the bottom of the hole 320 and integrally passes through the first groove 310, and the first groove 310 is located between the two side surfaces of the second groove 410.

The button 400 does not press the spring 500, i.e., when the spring 500 is in a natural state, the limiting protrusion 420 blocks the first groove 310, and the fastening clip 200 cannot be freely switched between the first state and the second state because the limiting protrusion 420 blocks the protrusion 240 from passing through the first groove 310. At this time, since the bottom surface of the fastening clip 200 abuts against the top surface of the base 100, the protrusion 240 abuts against the limiting protrusion 420 only when the fastening clip 200 is in the first state, so that the fastening clip 200 cannot be turned over relative to the base 100, and the fastening clip 200 is fixed on the base 100. When the fastening clip 200 needs to be switched from the first state to the second state, only the button 400 needs to be pressed to compress the spring 500, the limiting protrusion 420 moves towards the bottom of the hole, and when the limiting protrusion 420 integrally passes through the first groove 310 and the first groove 310 is located between two side surfaces of the second groove 410, the first groove 310 is restored to be smooth, so that the fastening clip 200 can be turned over to a state of being horizontally arranged on the base 100. Similarly, when the fastening clip 200 needs to be switched from the second state to the first state, the protrusion 240 may pass through the first groove 310 by only pressing the button 400 to restore the first groove 310, and the fastening clip 200 may be erected with the base 100.

Unlike the previous embodiment, in another embodiment, a tension spring is abutted between the bottom of the hole 320 and the button 400, the button 400 is provided with a second groove 410 having the same opening direction as the first groove 310, the side surface of the second groove 410 is provided with a limit protrusion 420, when the tension spring is in a natural state, the limit protrusion 420 is located in the first groove 310, and when the tension spring is stretched, the limit protrusion 420 moves towards the outside of the hole 320 and integrally passes through the first groove 310, and the first groove 310 is located between the two side surfaces of the second groove 410.

The button 400 does not stretch the tension spring, that is, when the tension spring is in a natural state, the limiting protrusion 420 blocks the first groove 310, and the fastening clip 200 cannot be freely switched between the first state and the second state because the limiting protrusion 420 blocks the protrusion 240 from passing through the first groove 310. At this time, since the bottom surface of the fastening clip 200 abuts against the top surface of the base 100, the protrusion 240 abuts against the limiting protrusion 420 only when the fastening clip 200 is in the first state, so that the fastening clip 200 cannot be turned over relative to the base 100, and the fastening clip 200 is fixed on the base 100. When the fastening clip 200 needs to be switched from the first state to the second state, only the button 400 needs to be pulled back to stretch the tension spring, the limiting protrusion 420 moves towards the outside of the hole, and when the limiting protrusion 420 integrally passes through the first groove 310 and the first groove 310 is located between two side surfaces of the second groove 410, the first groove 310 is restored to be smooth, so that the fastening clip 200 can be turned over to a state of being horizontally arranged on the base 100. Similarly, when the fastening clip 200 needs to be switched from the second state to the first state, the protrusion 240 may pass through the first groove 310 only by pulling back the button 400 to restore the first groove 310, and the fastening clip 200 may be erected with the base 100.

Referring to fig. 2-5, further, in the above embodiment, when the fastening clip 200 needs to be switched from the second state to the first state, the button 400 needs to be kept pressed or pulled back until the protrusion 240 entirely passes through the first groove 310. For optimal operation, in an embodiment, the sides of the limiting protrusion 420 are inclined, the second groove 410 is formed with a narrow opening side 411 and a flared opening side 412, the limiting protrusion 420 is located in the first groove 310 when the spring 500 is in a natural state, the first groove 310 is located between the two sides of the flared opening side 412, and when the spring 500 is compressed, the limiting protrusion 420 moves toward the bottom of the hole 320 and integrally passes through the first groove 310, and the first groove 310 is located between the two sides of the narrow opening side 411.

In the process of turning the fastening clip 200 from the second state to the first state, the spring 500 is in a natural state, the first groove 310 is located between two sides of the flared side 412, the protrusion 240 enters the second groove 410 from the flared side 412 without being blocked and abuts against the limiting protrusion inclined plane 421, the fastening clip 200 continues to turn, the limiting protrusion 420 is moved towards the bottom of the hole 320 due to being pressed by the protrusion 240, and the spring 500 between the button 400 and the bottom of the hole 320 is compressed. When the protrusion 240 is located at the narrow opening side 411 after passing through the second groove 410, the protrusion 240 does not press against the limiting protrusion inclined surface 421, the spring 500 is restored to a natural state that is not subjected to external force, and the limiting protrusion 420 moves toward the direction outside the hole 320 and is placed in the first groove 310 again. The stop protrusion 420 which is re-placed in the first recess 310 stops the protrusion 240 from rotating back, and the bottom surface of the fastening clip 200 abuts against the base 100, and the protrusion 240 abuts against the stop protrusion 420, so that the fastening clip 200 is kept in the first state and locked on the base 100. When the fastening clip 200 needs to be switched from the first state to the second state, only the button 400 needs to be pressed to compress the spring 500, so that the limiting protrusion 420 moves towards the bottom of the hole 320, the limiting protrusion 420 moves towards the bottom of the hole 320 and integrally passes through the first groove 310, the first groove 310 is located between two side surfaces of the narrow opening side 411, the protrusion 240 is not blocked from passing through the first groove 310, and meanwhile, an external force is applied to rotate the fastening clip 200, so that the protrusion 240 integrally passes through the first groove 310 again until the fastening clip 200 is horizontally arranged on the base 100. One end of the button 400, which is opposite to the bottom of the hole 320, is provided with a blocking piece, and the area of the blocking piece is larger than that of the hole 320, so that the button 400 is prevented from being integrally plugged into the hole 320.
