[0002] In clinical diagnosis in hospitals, patients often need to be given infusion therapy. Medical staff inject drugs into infusion bottles according to a certain ratio, and then complete the infusion therapy for patients through infusion tubes and infusion needles. During infusion, the pressure formed by the gravity of the drug solution can smoothly enter the human body's blood vessels, flow back to the heart along the blood in the veins, and then distribute to the whole body. When the liquid in the infusion bottle is infused, the pressure in the blood vessels is greater than that in the needle tube, which will form a backflow and produce blood return. In order to avoid this phenomenon, medical staff or patients need to monitor the infusion bottle regularly. Since the infusion process is relatively long, it is not realistic for personnel to continuously observe the infusion bottle, which leads to the hidden danger of blood reflux due to negligence. The existing device for automatically monitoring the liquid level of the infusion bottle is generally through a photoelectric liquid level sensor, etc. This device is generally set on the outside of the infusion bottle, but the drug bottle needs to be replaced many times during infusion therapy, resulting in the need to disassemble and assemble the monitoring device when the medical staff replaces the infusion bottle, and the operation is relatively complicated.

[0016] See also Figure 1-Figure 4 The utility model provides the following technical solutions: it includes a support frame 1, a monitoring chamber 2 is fixedly connected to the top of the support frame 1, a locking block 21 is slidably connected to one side of the monitoring chamber 2, a touch sensor 22 is fixedly connected to the top of the monitoring chamber 2, a guide column 23 is fixedly connected to the inner wall of the bottom end of the monitoring chamber 2, a positioning block 3 is slidably connected inside the monitoring chamber 2, the guide column 23 is slidably connected inside the positioning block 3, the positioning block 3 is engaged with the monitoring chamber 2 through the locking block 21, a placement groove 31 is opened inside the positioning block 3, and a contact block 32 is fixedly connected to the top of the positioning block 3.
[0017] In this embodiment: the support frame 1 is used to support various components to complete the work of infusing the patient, and through the cooperation of other components, the liquid level inside the infusion bottle can be monitored to avoid the situation where the liquid level is too low. The monitoring chamber 2 is fixed on the top of the support frame 1, so that the monitoring chamber 2 can be supported by the support frame 1 to a certain height from the ground, so that the infusion bottle placed on the inside of the monitoring chamber 2 can be higher than the human body, so that the medicine inside the infusion bottle can enter the human body through the pressure generated by gravity. The sliding engaging block 21 on one side of the monitoring chamber 2 is engaged with the positioning block 3, so that the engaging block 21 can limit the position of the positioning block 3 to avoid the movement of the positioning block 3. The positioning block 3 is used to support the infusion bottle. The positioning block A placement groove 31 corresponding to the shape of the infusion bottle is provided inside the positioning block 3, so that the medical staff can put the infusion bottle into the inner side of the positioning block 3, so that the medical staff can replace the medicine bottle more conveniently, and the infusion bottle will not fall over. The position of the contact block 32 fixed on the top of the positioning block 3 corresponds to the touch sensor 22 fixed on the top of the monitoring chamber 2. The outer side of the guide column 23 fixed on the inner wall of the bottom end of the monitoring chamber 2 has a spring, and the positioning block 3 slides on the outer side of the guide column 23, so that when the medical staff puts the infusion bottle into the inner side of the positioning block 3, the infusion bottle and the internal medicine will apply pressure to the positioning block 3, so that the positioning block 3 will slide vertically downward on the outer side of the guide column 23. As the infusion work progresses, the medicine inside the infusion bottle When the liquid becomes less, the pressure of the infusion bottle and the internal medicine liquid on the positioning block 3 will continue to decrease, so that the spring on the outside of the guide column 23 will slowly lift the positioning block 3 through the elastic release force, so as to achieve the purpose of monitoring the liquid level inside the medicine bottle. When the medicine inside the infusion bottle is finished, the positioning block 3 will be lifted to the top fixed contact block 32 to contact the touch sensor 22, so that the touch sensor 22 will alarm the outside world and prompt the medical staff to replace the infusion bottle. When the medical staff needs to perform infusion treatment on the patient, they can first connect the infusion bottle with the infusion tube and put the infusion bottle into the placement groove 31, so that the positioning block 3 will support the infusion bottle, and then the medical staff can complete the infusion of the patient through the infusion needle. During operation, the infusion bottle located inside the positioning block 3 will apply pressure to the positioning block 3 through the internal medicine liquid, so that the positioning block 3 will move vertically downward inside the monitoring chamber 2. At this time, the positioning block 3 will slide on the outside of the guide column 23. As the infusion work progresses, the medicine liquid in the temporal part of the infusion bottle will gradually decrease, so that the pressure of the infusion bottle and the internal medicine liquid borne by the positioning block 3 will become smaller. Since there is a spring on the outside of the guide column 23, when the downward pressure applied by the positioning block 3 becomes smaller, the spring will push the positioning block 3 upward through the force released by the elasticity, and as the medicine liquid decreases, the positioning block 3 will gradually be lifted upward. When the medicine liquid in the medicine bottle is infused, the positioning block 3 will be lifted to the position where the contact block 32 at the top contacts with the touch sensor 22.The touch sensor 22 will send out an alarm to the outside world, thereby reminding the medical staff to replace the infusion bottle, thereby achieving the purpose of monitoring the liquid level inside the infusion bottle. When there is no need to infuse the patient, the medical staff can slide the locking block 21 to the inside of the positioning block 3, so that the positioning block 3 cannot move, so that the contact block 32 fixed on the top of the positioning block 3 cannot contact the touch sensor 22, avoiding the situation that the contact block 32 contacts the touch sensor 22 and sends out an alarm to the outside world when there is no need to infuse the patient. Through the cooperation of the monitoring chamber 2 and the positioning block 3, the liquid level inside the infusion bottle can be continuously monitored when the patient is receiving infusion treatment, and an alarm is sent to the outside world after the medicine in the infusion bottle is infused, so that the medical staff can replace the medicine bottle in time, and through the cooperation of the positioning block 3 and the placement slot 31, it is more convenient for the medical staff to replace the infusion bottle.
[0018] A clearance groove 24 is provided on one side of the monitoring chamber 2 and the positioning block 3, and the positions of the two clearance grooves 24 correspond to each other; the clearance grooves 24 provided on one side of the monitoring chamber 2 and the positioning block 3 are used to make way for the infusion tube installed at the bottom of the infusion bottle, so that medical staff can place the infusion bottle to the inner side of the positioning block 3 to complete the monitoring of the liquid level of the infusion bottle.
[0019] A sliding groove 25 is provided inside the monitoring chamber 2, and the giving way groove 24 is connected to the sliding groove 25; the sliding groove 25 provided inside the monitoring chamber 2 is used to make room for the sliding of the positioning block 3, and the giving way groove 24 is connected to the sliding groove 25, so that when the positioning block 3 slides, it can drive the infusion bottle to move synchronously, avoiding the infusion bottle being unable to move with the positioning block 3 due to interference from the infusion tube.
[0020] A guide groove 33 is provided inside the positioning block 3, and the guide column 23 is slidably connected to the inside of the positioning block 3 through the guide groove 33; the guide groove 33 provided inside the positioning block 3 is used to make room for the sliding of the guide column 23, so that the positioning block 3 can slide on the outside of the guide column 23 when subjected to the pressure of the infusion bottle and the internal medicine liquid, so that when the medicine liquid becomes less, the spring outside the guide column 23 can gradually lift the positioning block 3 upwards to complete the monitoring of the liquid level.
[0021] A snap-fitting groove 34 is provided on one side of the positioning block 3, and the snap-fitting block 21 is slidably connected to the inside of the positioning block 3 through the snap-fitting groove 34; the snap-fitting groove 34 provided on one side of the positioning block 3 is used to make room for the sliding of the snap-fitting block 21, so that medical staff can slide the snap-fitting block 21 to the inside of the positioning block 3, thereby completing the snap-fitting work of the positioning block 3, so that when it is not in use, the position of the positioning block 3 can be limited to prevent the contact block 32 fixed at the top of the positioning block 3 from contacting the touch sensor 22.
[0022] The working principle and use process of the utility model: when the medical staff needs to perform infusion treatment on the patient, they can first connect the infusion bottle with the infusion tube, and put the infusion bottle into the placement groove 31, so that the positioning block 3 can support the infusion bottle, and then the medical staff can complete the infusion work for the patient through the infusion needle. The infusion bottle located inside the positioning block 3 will apply pressure to the positioning block 3 through the internal medicine liquid, so that the positioning block 3 will move vertically downward inside the monitoring chamber 2. At this time, the positioning block 3 will slide on the outside of the guide column 23. As the infusion work progresses, the medicine liquid in the temporal part of the infusion bottle will gradually decrease, so that the pressure of the infusion bottle and the internal medicine liquid borne by the positioning block 3 will become smaller. Because there is a spring on the outside of the guide column 23, when the downward pressure applied by the positioning block 3 becomes smaller After that, the spring will push the positioning block 3 upward through the force of elastic release, and as the medicine liquid decreases, the positioning block 3 will gradually be lifted upward. When the medicine in the medicine bottle is infused, the positioning block 3 will be lifted to the position where the contact block 32 at the top contacts with the touch sensor 22, so that the touch sensor 22 will sound an alarm to the outside world, thereby reminding medical staff to replace the infusion bottle, thereby achieving the purpose of monitoring the liquid level inside the infusion bottle. When there is no need to infuse the patient, the medical staff can slide the locking block 21 to the inside of the positioning block 3, so that the positioning block 3 cannot move, so that the contact block 32 fixed on the top of the positioning block 3 cannot contact with the touch sensor 22, thereby avoiding the situation where the contact block 32 contacts the touch sensor 22 and sends an alarm to the outside world when there is no need to infuse the patient.
