DETAILED DESCRIPTION

[0031] The technical solutions of the utility model will be described clearly and completely below in combination with the drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.

[0032] In the description of the utility model, it needs to be explained that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and cannot be understood as indicating or implying that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model. In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0033] In the description of the utility model, it is necessary to explain that, unless there are explicit provisions and limitations, the terms "installation", "connection", "connection" should be understood broadly, for example, it can be fixed connection, can also be detachable connection, or integrally connected;It can be mechanical connection, or electrical connection;It can be directly connected, or indirectly connected through an intermediate medium, it can be the communication between two elements inside.For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0034] As Figures 1-5 The utility model discloses a kind of multifunctional infusion monitoring and catheter clamping alarm, including a clamp plate group, which is composed of two pieces of elastic hinged clamp plate 1 by spring hinge realization.Equip at least one set of chuck group on the clamp plate group.The chuck group is composed of two chuck 2 respectively connected on the side of corresponding clamp plate, when two pieces of clamp plate are V-shaped closed under the action of elastic hinge, two chuck in chuck group are also synchronous closed and form a passage that can be clamped on infusion tube.Through the structure, the present scheme can be stably fixed on infusion tube.It needs to be explained, as preferred, to improve the stability of clamping, chuck group has two groups, and is divided and arranged at the upper and lower ends of clamp plate group, to be able to implement clamping to the infusion tube on the upper and lower ends of Murphy drip tube.

[0035] In addition, in order to monitor infusion state in real time, a droplet detector 6 is also installed on one of the clamp plates 1, which detects the liquid drop into the Murphy drip tube by infrared detection means, so as to judge in real time whether the infusion speed is within the safety threshold and whether the liquid infusion is completed.

[0036] At the same time, a battery 9 capable of realizing repeated charge and discharge is also installed on one of the clamp plates, which is electrically connected with the droplet detector to provide electric energy for the normal work of the droplet detector.

[0037] It should also be noted that after the droplet detector detects that the drug delivery rate exceeds the set value or the drug delivery is completed, safety protection measures such as alarm activation and clamping of the infusion tubing are required to improve the safety of the infusion. To achieve the above operations, a clamping mechanism 10 is installed on one of the clamps in the clamp assembly. This clamping mechanism is electrically connected to the droplet detector 6. When the droplet detector detects that the drip rate in the Murphy drip tube exceeds a preset threshold (the drip rate is below the lower limit of the set value or above the upper limit of the set value), it can drive the clamping mechanism to close the infusion tubing between the clamps. At the same time, an alarm 3 is also installed on the clamp plate and is electrically connected to the droplet detector 6. When the droplet detector cannot detect the drug dripping or the drip rate exceeds the set threshold, the droplet detector can drive the alarm 3 to sound an alarm. The alarm sound can be an explanatory voice such as "Your fluid drip rate is abnormal, the infusion tubing has been clamped."

[0038] It should be noted that the clamping mechanism 10 can take various forms in specific embodiments. The preferred embodiment in this solution includes a clamping block 101 with sliding grooves 102 on both sides, and a return spring 103 disposed within each groove. Simultaneously, a travel groove 106 is formed on the upper surface of the clamping block 101, and a traction rope 105 is disposed within this groove, with one end of the traction rope connected to the groove wall at one end.

[0039] Correspondingly, a through groove 21 is formed on the chuck 2 where the clamping mechanism is located, directly opposite the clamping surface of another chuck in the chuck assembly. A slide rail 22 extending in the same direction as the groove is also provided within this groove. Figure 4 , Figure 5 As shown, the clamping block slides into the slide groove, and the end face of the slide rail abuts against one end of the return spring installed in the slide groove, so that the return spring can be compressed and stored when the clamping block slides in the slide groove. It should be noted that, in order to drive the clamping block to slide in the slide groove and clamp the infusion tube when the infusion is completed, a micro motor 104 is also installed on the clamping head. This micro motor is electrically connected to the droplet detector 6. Simultaneously, the output shaft of the micro motor can rotatably pass through the clamping head and extend into the stroke groove 106. Figure 4 As shown, the other end of the traction rope located in the travel groove is wound around the output shaft of the micro motor. When the droplet detector detects that the drug delivery is complete, it drives the micro motor to rotate, and the micro motor further winds the traction rope to bring the clamping block closer to the clamping surface of the other clamp.

[0040] Additionally, it should be noted that the droplet detector is susceptible to interference from external photoelectric signals when detecting the dripping liquid. To address this, an arc-shaped baffle 5 can be installed on the side edges of each of the two clamping plates. When the baffles on the two clamping plates 1 are driven to close, they surround the outside of the Morpheus dropper, reducing interference from external photoelectric signals to the droplet detector.

[0041] Furthermore, it should be noted that the required infusion rate varies depending on the specific medication. To better adapt this solution to the detection needs of different infusion rates, an LCD screen controller 4 is also installed on one of the clamping plates 1 in this solution. This LCD screen controller is electrically connected to the droplet detector and has external control keys. The trigger threshold of the droplet detector is adjusted via these control keys. It should be noted that in this solution, the LCD screen controller 4 can display the real-time droplet rate detected by the droplet detector and the alarm threshold set via the control keys.

[0042] In addition, in cold environments, to improve comfort during infusion, a heating device 8 can be added. This heating device can heat the medication flowing through the infusion tube to increase the temperature of the medication being administered to the patient.

[0043] It should be noted that the heating mechanism 8 in this solution is a detachable structure, allowing it to be removed promptly when not in use. Specifically, one of the clamps 2 is equipped with a socket 11 that is electrically connected to the battery 9. This socket can be a Type-C or USB connector. The heating mechanism can be inserted into this socket 11 to establish an electrical connection with the battery 9.

[0044] Furthermore, to facilitate the heating of the medication in the infusion tube, the heating mechanism 8 includes a heating plate 81 that can heat to 35-40°C when energized. The heating plate has a groove 82 for the infusion tube to be inserted into, extending in a "U" shape to verify the contact length between the infusion tube and the heating plate. Simultaneously, the heating plate also has several clips 83 evenly arranged along the extension direction of the groove to secure the infusion tube embedded in the groove.

[0045] In addition, preferably, the buckle can be made of elastic silicone material so that the buckle 83 can be pried open more easily when the infusion tube is inserted into the tubing groove.

[0046] Finally, a hanging ring 7 is also provided on the clamp assembly so that the solution can be hung on the infusion stand synchronously with the infusion bag, so as to prevent the solution from falling off the infusion tube or from applying too much force to the infusion tube, which would cause the infusion tube to bend.

[0047] Working Principle: When intravenous infusion is required, medical staff squeeze the clamp assembly to open the clamp group, then insert the infusion tubing into the channel of the clamp assembly, ensuring the droplet detector is aligned with the Morpheus drip chamber. The detection threshold of the droplet detector is then adjusted via the LCD controller. After these steps are completed, the droplet detector can be activated for infusion monitoring. During the infusion process, if the drip rate triggers the set upper or lower threshold, the droplet detector will activate the alarm. If the droplet detector fails to detect a drop, or if the drip rate exceeds the threshold (exceeding or exceeding the set upper or lower limits), the clamping mechanism will activate to clamp the infusion tubing, preventing blood backflow, air entering the patient's blood vessels through the infusion tubing, or discomfort caused by an inappropriate infusion rate. In addition, when the weather is cold, the heating mechanism in this solution can be installed through a socket. At this time, the infusion tube is inserted into the tube groove and fixed with a buckle. When the medicine flows through the infusion tube, the heating plate on the outside of the medicine heats the medicine flowing through the infusion tube to improve the comfort of infusion.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
