Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and relates to a bubble detection device, particularly to a bubble detection device for an infusion set. Background Technology

[0002] An infusion set is a tubular passage connecting a medication bottle to a vein. Its core components include a trocar for inserting the medication bottle, a drip chamber for monitoring the drip rate and air intake, a regulator for controlling the flow rate, and the intravenous infusion needle at the tip. Utilizing atmospheric pressure and gravity, it continuously delivers medication into the patient's bloodstream in a sterile and controlled manner, making it one of the most commonly used drug delivery tools in medicine. Occasionally, air bubbles may form in an infusion set during use. These bubbles usually originate from incomplete air venting, leaks at the connection, or emptying of the infusion line. Small amounts of tiny bubbles are generally harmless and will be absorbed and metabolized by the body; there is no need to panic. However, if any bubbles are found, the regulator should be immediately turned off, and the bubbles should be expelled back into the drip chamber by squeezing the tubing.

[0003] During routine treatment, the slow infusion rate of oil-based fluids makes it difficult to promptly detect changes in the fluid tubing of the infusion set, which can easily lead to backflow of blood and other complications, resulting in accidents. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing an easy-to-use infusion set bubble detection device that prevents air bubbles and backflow of blood.

[0005] The objective of this utility model can be achieved through the following technical solution: an infusion set bubble detection device, characterized in that it includes a left shell and a right shell connected by hinges, the left shell and the right shell are provided with symmetrical infusion tube through slots, the infusion tube through slots are connected to each other, a laser emitter is provided on the side wall of the left shell, and a rotating shaft is provided at both ends of the laser emitter. A control fork is provided at the end of the laser emitter, the control fork is provided with an internal thread hole, the internal thread hole is provided with a control rotating shaft, a support bearing is provided inside the left shell, the control rotating shaft is fixed to the support bearing, an end cap is provided on the top of both the left shell and the right shell, the control rotating shaft protrudes from the end cap, and a photosensitive detector is provided on the right shell.

[0006] In the above-mentioned infusion set bubble detection device, the right shell is equipped with a power supply and control box, and the left and right shells are each equipped with a number of conductive posts that abut against each other. The power supply is connected to the conductive posts, the photosensitive detector and the controller, the laser emitter is connected to the conductive posts, and the control box is equipped with a buzzer.

[0007] In the aforementioned infusion set bubble detection device, several magnets are provided on the outer walls of the left and right shells.

[0008] In the aforementioned infusion set bubble detection device, the infusion tube through slot is provided with several sealing semi-circles, the ends of which abut against each other.

[0009] In the aforementioned infusion set bubble detection device, a control button is provided on the top of the left housing, and a power interface is provided on the bottom of the left housing. A flexible keycap is provided on the top of the control shaft.

[0010] In the aforementioned infusion set bubble detection device, both the left and right housings are provided with guide grooves.

[0011] Compared with existing technologies, this infusion set bubble detection device uses the refraction of light propagating between different media to detect whether there are air bubbles or backflow in the infusion tube, reducing the user's wasted energy and anxiety during infusion. The adjustable laser emitter can adapt to different liquids by changing the angle, making this detection device suitable for more usage scenarios. The hinged structure combined with magnets makes it easier to assemble and disassemble. The sealed semi-circles abut against each other and gently squeeze the infusion tube to reduce the device from slipping. Attached Figure Description

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figure 1 , 2As shown in Figures 3 and 4, this infusion set bubble detection device is characterized by comprising a left housing 5 and a right housing 8 hinged together. Symmetrical infusion tube through-holes 10 are provided on the left housing 5 and right housing 8, and the infusion tube through-holes 10 are interlocked. A laser emitter 12 is provided on the side wall of the left housing 5, and a rotating shaft 20 is provided at both ends of the laser emitter 12. A control fork 19 is provided at the end of the laser emitter 12, and an internal threaded hole 21 is provided on the control fork 19. A control rotating shaft 15 is provided on the internal threaded hole 21. A support bearing 14 is provided inside the left housing 5, and the control rotating shaft 15 is fixed to the support bearing 14. The left housing 5 and the right housing... Each of the 8 units has an end cap 1 on top. The control shaft 15 protrudes from the end cap 1. The right housing 8 is equipped with a photodetector 16. Before use, the infusion tube is placed in the slot of the infusion tube, and the left housing 5 and the right housing 8 are joined together. The power supply 11 is turned on, and the laser emitter 12 emits a laser through the infusion tube and projects it onto the photodetector 16. When in use, when the bubble passes through the laser projection path, the laser projection path changes, and the laser cannot be projected onto the photodetector 16 along the original path. Different solutions have different refractive indices. By rotating the control shaft 15, the laser emitter 12 can be deflected at an angle until the laser can be projected onto the photodetector 16.

[0019] Preferably, the right housing 8 contains a power supply 11 and a control box 17. Both the left housing 5 and the right housing 8 have several conductive posts 13 that abut against each other. The power supply 11 connects to the conductive posts 13, the photodetector 16, and the controller. The laser emitter 12 is connected to the conductive posts 13. The control box 17 has a buzzer 18. Power is supplied to the laser emitter 12 through the contact of multiple conductive posts 13. After the laser is refracted, it shines on the photodetector 16 and remains normal. When bubbles are generated or blood returns, the light source shifts and the photodetector 16 can no longer detect the light source. The buzzer 18 then sounds an alarm to alert the user.

[0020] Preferably, the left housing 5 and the right housing 8 are provided with several magnets on their outer walls, and the left and right housings 8 are connected by magnets 7 to prevent them from falling off during use.

[0021] Preferably, the infusion tube through slot 10 is provided with several sealing semi-circles 6, the ends of the sealing semi-circles 6 abutting each other, and two sealing semi-circles 6 form a sealing ring, which can better fix it on the infusion tube.

[0022] Preferably, the left housing 5 has a control button 3 on the top and a power interface 9 on the bottom, and the control shaft 15 has a flexible keycap 2 on the top.

[0023] Preferably, both the left shell 5 and the right shell 8 are provided with guide grooves 4. The guide grooves 4 increase the opening and closing angle of the left and right shells to adapt to different usage environments.

[0024] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0025] Although this document frequently uses terms such as end cap 1, flexible keycap 2, control button 3, guide groove 4, left shell 5, sealing half ring 6, magnet 7, right shell 8, power interface 9, infusion tube through slot 10, power supply 11, laser emitter 12, conductive post 13, support bearing 14, control shaft 15, photosensor 16, control box 17, buzzer 18, control fork 19, shaft 20, and internal threaded hole 21, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
