Description

Technical Field

[0001] The utility model relates to the technical field of infusion monitoring, in particular to an infusion monitoring device for an infusion stand. Background Technique

[0002] During the clinical infusion process, when the infusion is completed to end the current treatment or change the dressing, etc., most of the situations are observed and detected by patients, companions, and medical staff at any time, and are handled by medical staff. However, patients may easily get tired due to illness, long infusion time, etc. In particular, medical staff cannot pull out the needle or change the dressing in time when there is a shortage of staff. Therefore, an infusion monitoring device for an infusion stand is needed to monitor the remaining amount of the liquid medicine in the infusion bottle and remind medical staff or patients in time according to the remaining amount.

[0003] The utility model with the existing authorized publication number CN216566276U discloses an infusion remaining amount monitoring device, including an infusion bag, an infusion stand, a pressure sensor, a display device, a metal disc, an upper rope, and a lower rope. The infusion stand includes a hanging rod and a hanging hook. The infusion bag is connected to the infusion stand through the hanging opening at its top. A pressure sensor is arranged inside the bottom end of the infusion stand.

[0004] Adopting the above technical solution, the metal disc can exert a squeezing effect on the pressure sensor. The pressure of the metal disc on the sensor is equal to the gravity of the remaining liquid. Thus, the pressure sensor can collect the remaining liquid weight data and transmit it to the display device for display. However, in the above technical solution, when the infusion monitoring device of the infusion stand is in use, it can only monitor the remaining amount of the liquid medicine in the infusion bottle and remind, and cannot cut off the liquid flow in the infusion tube in time. After the liquid medicine in the infusion tube runs out, blood return is likely to occur, which cannot provide more sufficient time for medical staff to come and pull out the needle. At the same time, the protection effect on the liquid medicine in the infusion bottle is poor, and it cannot block light for some light-sensitive liquid medicines, greatly affecting the overall use effect of the infusion monitoring device of the infusion stand.

[0005] Therefore, those skilled in the art provide an infusion monitoring device for an infusion stand to solve the problems raised in the above background technique. Content of the Utility Model

[0011] As a further scheme of the utility model: two stabilizing frames are fixedly connected to the right side surface of the clamping block, and the upper surface of each stabilizing frame is fixedly connected to the outer surface of the clamping frame.

[0012] As a further scheme of the utility model: a fixing plate is fixedly connected to the upper surface of the sliding frame, and the upper surface of the fixing plate is fixedly connected to the outer surface of the clamping frame.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0017] By arranging a pressure sensor, the utility model can judge the remaining amount of the liquid medicine in the infusion bottle by monitoring the weight of the infusion bottle.

Detailed implementation manner

[0024] Please refer to Figures 1-5 , an infusion stand infusion monitoring device, including a fixed frame 1, two pressure sensors 2 are slidably connected inside the fixed frame 1, a clamping frame 3 is slidably connected inside the fixed frame 1, the bottom surface of the clamping frame 3 is in contact with the sensing end of the pressure sensor 2, a clamping mechanism 4 is fixedly connected to the bottom surface of the clamping frame 3, a light-shielding mechanism 5 is arranged above the fixed frame 1, a compression spring 6 is fixedly connected to the bottom surface of each pressure sensor 2, and the bottom end of each compression spring 6 is fixedly connected to the inner bottom wall of the fixed frame 1. An alarm lamp 7 and a buzzer 8 are fixedly connected to the left side surface of the fixed frame 1 respectively, and both the alarm lamp 7 and the buzzer 8 are electrically connected to the pressure sensor 2 through wires. The compression spring 6 can provide a buffering force for the pressure sensor 2 while not affecting the operation of the pressure sensor 2, preventing the clamping frame 3 from damaging the pressure sensor 2, and the alarm lamp 7 and the buzzer 8 can emit warning lights and alarm sounds when the pressure sensor 2 detects that the remaining amount of the liquid medicine is too small.

[0025] The clamping mechanism 4 includes a clamping block 401. Two stabilizing frames 9 are fixedly connected to the right side surface of the clamping block 401, and the upper surface of each stabilizing frame 9 is fixedly connected to the outer surface of the clamping frame 3. The stabilizing frame 9 can fix the position of the clamping block 401, keep the clamping block 401 at a proper height from the clamping frame 3, and ensure the normal use of the clamping block 401.

[0026] The back surface of the clamping block 401 is fixedly connected to a sliding frame 402. A screw 403 is rotatably connected inside the sliding frame 402. A servo motor 404 is fixedly connected to the left side surface of the sliding frame 402. The servo motor 404 is electrically connected to the pressure sensor 2 through a wire. A fixing plate 10 is fixedly connected to the upper surface of the sliding frame 402, and the upper surface of the fixing plate 10 is fixedly connected to the outer surface of the clamping frame 3. The fixing plate 10 can reinforce the sliding frame 402, making the sliding frame 402 not easily loosen excessively, and improving the reliability of use of the sliding frame 402.

[0027] The output end of the servo motor 404 power passes through the sliding frame 402 and is fixedly connected to the left end of the screw 403. The outer surface of the screw 403 is threadedly connected to the sliding block 405. The right end of the screw 403 is sleeved with an auxiliary bearing 11, and the auxiliary bearing 11 is fixedly embedded in the interior of the sliding frame 402. The auxiliary bearing 11 can limit the screw 403 while increasing the smoothness of the rotation of the screw 403, effectively reducing the wear between the screw 403 and the sliding frame 402.

[0028] The sliding block 405 is slidably connected to the inside of the sliding frame 402, and a clamping column 406 is arranged on the front of the sliding frame 402. One end of the clamping column 406 close to the sliding frame 402 is fixedly connected to the front of the sliding block 405. An auxiliary groove 12 is provided on the upper surface of the sliding frame 402. An auxiliary block 13 is slidably connected to the inside of the auxiliary groove 12. The bottom surface of the auxiliary block 13 is fixedly connected to the upper surface of the sliding block 405. The auxiliary block 13 slides inside the auxiliary groove 12, which can increase the stability of the sliding block 405 when it slides left and right, making the sliding block 405 more stable and reliable when sliding.

[0029] The shading mechanism 5 includes a hanging frame 501, the bottom surface of the hanging frame 501 is movably hinged to the upper surface of the fixing frame 1, the outer surface of the hanging frame 501 is fixedly connected with an elastic shading cloth 502, the inner part of the elastic shading cloth 502 is slidably connected with a tightening belt 503, the front of the clamping block 401 is movably hinged with a baffle 14, the back of the baffle 14 is in contact with the end of the clamping column 406 away from the sliding frame 402, the back of the baffle 14 is fixedly connected with a limiting spring 15, the end of the limiting spring 15 away from the baffle 14 is fixedly connected to the inner wall of the clamping block 401, the elastic force provided by the limiting spring 15 can be used to drive the baffle 14 to always keep in contact with the clamping column 406, when the infusion tube needs to be placed between the clamping block 401 and the clamping column 406, it is only necessary to pull the baffle 14 to force the limiting spring 15 to stretch, and the baffle 14 can be opened to put in the infusion tube.

[0030] The working principle of the present utility model is as follows: When in use, first, utilize the movable hinge relationship between the hanging bracket 501 and the fixed bracket 1 to pull the hanging bracket 501 backward, so that the infusion bottle is placed into the fixed bracket 1 and the clamping bracket 3. Then, hang the device on the infusion rack through the hook on the hanging bracket 501. Next, pull the baffle 14 to force the limit spring 15 to stretch, open the baffle 14, and place the infusion tube between the clamping block 401 and the clamping column 406. Since the weight of the infusion bottle will press down on the clamping bracket 3, forcing the compression spring 6 to contract, at the same time, the pressure sensor 2 can monitor this pressure value. When the weight is less than the internal set value of the pressure sensor 2, the pressure sensor 2 will send an electrical signal to the servo motor 404 through the wire to make it start working. Using the power provided by the servo motor 404 and cooperating with the sliding bracket 402, the screw rod 403 can be driven to rotate. At this time, the sliding block 405 threadedly connected to the screw rod 403 can drive the clamping column 406 to approach the clamping block 401. The groove on the clamping block 401 and the clamping column 406 can be used to clamp the infusion tube flat, stopping the flow of the liquid medicine in the infusion tube, thereby preventing the problem of blood backflow in patients due to the liquid medicine flowing out completely before the medical staff arrive in time. The infusion rack infusion monitoring device can not only monitor the remaining amount of the liquid medicine, but also cut off the liquid flow of the infusion tube in time, providing more sufficient time for the medical staff to come and pull out the needle. Through the cooperation of the hanging bracket 501 and the elastic light-shielding cloth 502, when some special drugs need to be infused under light shielding to ensure the drug effect, the elastic light-shielding cloth 502 can be pulled down to cover the clamping bracket 3 and the bottom of the elastic light-shielding cloth 502 can be tightened by the tightening belt 503 to shield the special liquid medicine, increasing the protection effect on the special liquid medicine when the infusion rack infusion monitoring device is in use, enabling it to play a certain role in light shielding, greatly increasing the overall use effect of the infusion rack infusion monitoring device. Moreover, the elastic light-shielding cloth 502 will not block the alarm sound of the buzzer 8, and since the alarm lamp 7 is in close contact with the elastic light-shielding cloth 502, some light can still leak out, so it will not overly affect the alarm reminder effect of the infusion monitoring device.

[0031] The above-mentioned is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent replacements or changes should be covered within the protection scope of the present utility model.
