[0029] In order to make the technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] like Figures 1 to 5 As shown, the utility model provides an infusion rod control device, comprising: an infusion rod 2, a sleeve 7, a fixing frame, a push rod 5, a pull rod 10, a transfer rod 12 and a connecting rod 13;

[0031] The sleeve 7 is provided with a hollow accommodating cavity for accommodating the infusion rod 2;

[0032] The fixing frame is fixed on the outer surface of the sleeve 7; the push rod 5 is slidably connected to the upper part of the fixing frame, and the push rod 5 is provided with a first spring 4; the pull rod 10 is slidably connected to the lower part of the fixing frame, and the pull rod 10 is provided with a second spring 9;

[0033] The top of the connecting rod 13 abuts against the front end of the push rod 5, and the bottom thereof is rotatably connected to the rear end of the pull rod 10; one end of the transfer rod 12 is rotatably connected to the middle of the connecting rod 13, and the other end of the transfer rod 12 is rotatably connected to the fixed frame, and the axes of the push rod 5, the connecting rod 13, the transfer rod 12 and the pull rod 10 are located in the same plane;

[0034] An opening is provided on the side wall of the sleeve 7 at a position corresponding to the pull rod 10 ; and at least one slot 22 matching the front end of the pull rod is provided on the infusion rod 2 .

[0035] In the technical solution of the utility model, the above-mentioned infusion pole control device can be fixed on the medical equipment. Figures 2 to 4 When the infusion pole 2 needs to be set on the medical device, the push rod 5 can be pushed or pressed forward to push the top of the connecting rod 13 forward, and the rotation of the connecting rod 13 and the adapter rod 12 can be used to drive the pull rod 10 to move backward. At the same time, the first spring 4 on the push rod 5 and the second spring 9 on the pull rod 10 are compressed. At this time, the infusion rod control device is in an unlocked state, and the infusion rod 2 can be placed in the sleeve 7, and the slot 22 on the infusion rod 2 can be made to correspond to the opening on the side wall of the sleeve 7. Then the push rod 5 is released. Under the action of the rebound force of the first spring 4 and the second spring 9, the push rod 5 moves backward and the pull rod 10 moves forward. At the same time, the adapter rod 12 and the connecting rod 13 are linked until the front end of the pull rod 10 passes through the opening on the side wall of the sleeve 7 and is stuck in the slot 22 on the infusion rod 2. Thereby, the infusion rod can be limited by the front end of the pull rod 10 to be fixed in the sleeve 7. At this time, the infusion rod control device is in a locked state, that is, the infusion rod is installed on the medical device.

[0036] Similarly, when the infusion rod needs to be removed from the sleeve 7, the push rod 5 can be pushed or pressed to drive the pull rod 10 to move backward, thereby releasing the limit of the infusion rod by the pull rod 10 and unlocking it, so that the infusion rod can be removed from the sleeve 7 or the medical device.

[0037] It can be seen from this that the above-mentioned infusion pole control device provided by the utility model enables the infusion pole to be disassembled and assembled on the medical equipment at any time, so that the infusion pole can be installed on the medical equipment and used together with the medical equipment, and the infusion pole can also be removed separately for use by the patient, and the disassembly and assembly operation of the infusion pole is simple, which provides convenience for medical staff and patients.

[0038] In the technical solution of the present utility model, a variety of implementation methods can be used to implement the above-mentioned infusion pole control device. The following will take one of the implementation methods as an example to introduce the technical solution of the present utility model in detail.

[0039] For example, preferably, in a specific embodiment of the present invention, Figures 1 to 3 As shown, the fixing frame may include: a push rod fixing frame 3, a pull rod fixing frame 8 and a push rod supporting frame 6;

[0040] The push rod fixing frame 3 and the pull rod fixing frame 8 can both be U-shaped plates, the open ends of the U-shaped plates are fixed to the outer surface of the sleeve 7, and the closed ends thereof are respectively provided with a first through hole and a second through hole;

[0041] The front end of the push rod 5 passes through the first through hole on the push rod fixing frame 3 and abuts against the top of the connecting rod 13. The push rod support bracket 6 is fixed on the push rod fixing frame 3 and limits the push rod 5 to prevent the push rod 5 from falling.

[0042] The rear end of the pull rod 10 passes through the second through hole on the pull rod fixing frame 8 and is rotatably connected to the bottom of the connecting rod 13 .

[0043] Preferably, as an example, an extension plate 81 extending backwards may be provided at a position of the upper portion of the pull rod fixing frame 8 corresponding to the transfer rod 12 , so as to facilitate the transfer rod 12 to be rotatably connected to the extension plate 81 .

[0044] For another example, preferably, in a specific embodiment of the present utility model, Figure 2 and Figure 3 As shown, the push rod 5 has a first raised limiting strip 51, and the push rod at the front end of the first raised limiting strip 51 is sleeved with a first spring 4, and the first spring 4 is located between the push rod fixing frame 3 and the raised limiting strip 51; the part of the push rod located at the rear end of the first raised limiting strip 51 passes through a preset through hole on the push rod support bracket 6 to form a pressing portion 52. By placing the first spring 4 sleeved on the push rod between the push rod fixing frame 3 and the raised limiting strip 51, the push rod 5 can automatically rebound and move backward under the action of the rebound force of the first spring 4 to achieve reset.

[0045] Preferably, as an example, in a specific embodiment of the present utility model, the front end of the push rod support bracket 6 can be fixed on the push rod fixing bracket 3, and the rear end thereof is bent upward to form a bent portion, and a through hole for the rear end of the push rod to pass through is provided on the bent portion. By providing the push rod support bracket 6 and providing the bent portion at its rear end, on the one hand, the push rod 5 can be supported to prevent the push rod 5 from falling off; on the other hand, the pressing portion can slide in the through hole on the bent portion to complete the pressing operation control.

[0046] In the technical solution of the utility model, the pressing portion 52 at the rear end of the push rod 5 can be pressed so that the pressing portion 52 can slide in the through hole on the push rod support bracket 6, and the first protruding limiting strip 51 on the push rod can limit the pressing portion 52 to prevent the push rod 5 from falling off from the through hole on the push rod support bracket 6. In addition, by placing the first spring 4 sleeved on the push rod between the push rod fixing frame 3 and the first protruding limiting strip 51, the first spring 3 can be limited to prevent the first spring from falling off, and when the pressing portion 52 at the rear end of the push rod is pressed, the first spring 4 is compressed and has a rebound force under the pushing action of the first protruding limiting strip 51, so that when the pressing portion 52 is released, the push rod 5 automatically rebounds and moves backward under the action of the rebound force of the first spring 4, so that the pressing portion 52 is completely ejected to the outside of the through hole of the push rod support bracket 6, which is convenient for the next pressing.

[0047] For another example, preferably, in a specific embodiment of the present utility model, Figure 2 and Figure 3 As shown, the pull rod 10 has a second raised limit strip 101, and the part of the pull rod located at the front end of the second raised limit strip 101 can pass forward through the opening on the side wall of the sleeve 7; the part of the pull rod located at the rear end of the second raised limit strip 101 is sleeved with a second spring 9, and the second spring 9 is located between the pull rod fixing frame 8 and the second raised limit strip 101.

[0048] Preferably, as an example, in a specific embodiment of the present utility model, a connecting portion 11 is provided at the rear end of the pull rod 10, and the connecting portion 11 is rotatably connected to the bottom of the connecting rod 13 via a rotating shaft.

[0049] Preferably, as an example, the connecting portion 11 and the rear end of the pull rod 10 may be connected by threads.

[0050] In the technical solution of the utility model, when the pressing portion 52 of the push rod is in the released state, the front end of the pull rod 10 passes through the opening on the side wall of the sleeve 7 and can be stuck in the slot 22 of the infusion rod 2. At this time, the second raised limiting strip 101 on the pull rod 10 can limit and stabilize the pull rod; by arranging the second spring 9 between the pull rod fixing frame 8 and the second raised limiting strip 101, when the pressing portion 52 of the push rod is pressed, the pull rod 10 is pulled backward under the linkage of the connecting rod 13 and the transfer rod 12, and the second raised limiting strip 101 on it compresses the second spring 9 backward, so that it is in a compressed state and has a rebound force. When the pressing portion 52 of the push rod is released, under the action of the rebound force of the second spring 9, the front end of the pull rod 10 moves forward, and when an infusion rod is placed in the sleeve 7, the front end of the pull rod 10 can automatically pass back into the slot 22 of the infusion rod to fix the infusion rod.

[0051] In addition, as an example, in a preferred specific embodiment of the present invention, Figure 4 As shown, the infusion pole 2 may be provided with a plurality of slots 22 at intervals, and the front end of the pull rod 10 may be adjusted so as to be stuck in different slots 22, thereby adjusting the height of the infusion pole according to actual needs.

[0052] Preferably, as an example, a hook 21 is provided on the top of the infusion pole 2 for hanging an infusion bag or an infusion bottle.

[0053] In addition, as an example, in a preferred specific embodiment of the present utility model, as Figures 2 to 5 As shown, the push rod fixing frame 3 and the pull rod fixing frame 8 can be fixed on the outer side of the sleeve 7 through a connecting plate 72, and a transverse fixing plate is provided on the top of the connecting plate 72 for fixed connection with the medical device.

[0054] Preferably, as an example, the connecting plate 72 can be further fixedly connected to the medical device via the connecting member 1.

[0055] In addition, as an example, in a preferred specific embodiment of the present invention, the length of the pull rod fixing frame 8 can be smaller than the length of the push rod fixing frame 3, and is located directly below the push rod fixing frame 3, so that the push rod 5, the connecting rod 13, the transfer rod 12 and the pull rod 10 can be located in the same vertical plane.

[0056] According to another aspect of the present application, an intra-aortic balloon pump is also provided. The intra-aortic balloon pump includes a movable shell, in which the infusion rod control device of the above-mentioned embodiments is integrated, and the rear end of the push rod extends a predetermined length from the outer surface of the shell. The predetermined length satisfies: after pressing the rear end of the push rod, the front end of the pull rod withdraws from the slot of the infusion rod to unlock the infusion rod. After releasing the rear end of the push rod, the front end of the pull rod extends into the hollow cavity of the sleeve again. If an infusion rod is inserted into the sleeve, the front end of the pull rod cooperates with the slot of the infusion rod to lock the infusion rod.

[0057] To sum up, in the technical solution of the utility model, by pressing the rear end of the push rod, the connecting rod 13, the adapter rod 12 and the pull rod 10 are linked, and by arranging the first spring and the second spring on the push rod and the pull rod, the front end of the pull rod can unlock and automatically lock the infusion rod, so that the infusion rod can be easily disassembled from the sleeve 7, so that the infusion rod can be installed on the medical equipment and used together with the medical equipment, and the infusion rod can also be removed separately for use by the patient, and the disassembly and assembly operation of the infusion rod is simple, which provides convenience for medical staff and patients.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
