[0002] Peristaltic pumps are commonly used medical devices. Peristaltic pumps are like squeezing a fluid-filled hose with your fingers. As your fingers slide forward, the fluid in the tube moves forward. The peristaltic pump is composed of a pump housing, a pump head, and a hose. A driving device is provided in the pump housing, in which the hose passes through the pump head as a whole. When in use, the two ends of the hose will be externally connected, and then the driving device will be started to realize the flow and transmission of the fluid in the hose.

[0003] After searching, a portable peristaltic pump with announcement number CN216975188U includes a pump housing, a pump head and a control panel are provided at the front end of the pump housing, a hose is passed through the pump head, a fixed block is provided at the side end of the pump housing, a screw groove is provided on the fixed block, a slide groove is provided at the side end of the pump housing, a slide seat is slidably connected in the slide groove, a slide block is provided on the slide seat, a groove is provided on the fixed block and the slide block, a damping buckle sleeve is provided in the groove, a handle is provided at the top of the pump housing, and a threaded column is provided on the fixed block.

[0004] Based on the above patent, the existing peristaltic pump mentioned in its background technology has both ends of its hose drooping when it is carried. After carrying for a long time, it not only has poor appearance, but also is likely to collide with external hard objects and cause scratches. In response to this technical problem, this application proposes a medical operating room cleanliness detection device. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a convenient peristaltic pump is proposed. The two winding tubes are driven to rotate by rotating the rotating wheel to engage with the gear one and the gear two, so as to wind the hose and prevent the hose from leaking out and causing damage. At the same time, the cooperation between the limit plate one and the limit plate two can prevent the hose from being retracted into the interior of the shell and being inconvenient to be taken out.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a portable peristaltic pump, comprising a shell, the inner wall of the bottom side of the shell is fixedly connected to the peristaltic pump body, a hose is arranged inside the peristaltic pump body, the inner wall of the rear side of the shell is rotatably connected to two winding rollers, the hose is sleeved on the outer wall of the winding roller, the front sides of the two winding rollers are connected by a gear set, the left and right sides of the shell are fixedly connected to guide tubes, and the inner wall of the guide tube is connected to the hose through a limit assembly.

At the same time, when the hose is retracted, the cooperation between the limit plate 1 and the limit plate 2 and the spring can prevent the hose from being wound too much and causing the hose and the guide tube to separate, causing difficulties for subsequent instructions.

[0008] Furthermore, the gear set includes two gears 1 located at the front sides of the two winding rollers respectively and two gears 2 located at the inner wall of the front side of the shell, and the two gears 2 are meshingly connected.

[0009] Through the above technical solution, the transmission of the two gears 2 drives the gear 1 on the left to rotate, thereby driving the winding roller to rotate and wind the hose.

[0010] Furthermore, the gear one on the right side and the gear two on the right side are meshedly connected, and the gear one on the left side and the gear two on the left side are meshedly connected.

[0011] Through the above technical solution, the right gear one drives the left gear one to rotate through the meshing transmission between the two gears two.

[0012] Furthermore, a front side of the right gear is fixedly connected with a rotating wheel.

[0013] Through the above technical solution, the right gear is driven to rotate by rotating the rotating wheel.

[0014] Furthermore, the limiting assembly includes a limiting plate 2 slidably connected to the outer wall of the hose, a limiting plate 1 is arranged on the side of the limiting plate 2 away from the peristaltic pump body, the limiting plate 1 is fixedly connected to the outer wall of the hose, and a spring is arranged between the limiting plate 2 and the limiting plate 1.

[0015] Through the above technical solution, the limiting plate 1 and the limiting plate 2 cooperate with each other when the hose is wound, so as to prevent the hose from being excessively wound and being stuck inside the guide tube.

[0016] Furthermore, one end of the spring is fixedly connected to a side of the limiting plate 2 facing the limiting plate 1, and the other end of the spring is fixedly connected to a side of the limiting plate 1 facing the limiting plate 2.

[0017] Through the above technical solution, the action of the spring cooperates with the limiting plate 1 and the limiting plate 2 to prevent the hose from being excessively received inside the hose.

[0018] Furthermore, a handle is fixedly connected to the top side of the shell.

[0019] Through the above technical solution, the handle makes it convenient for workers to carry the peristaltic pump, thereby achieving portability.

[0020] The utility model has the following beneficial effects:

[0021] 1. In the utility model, the winding roller is driven to reel in the hose through the cooperation between the gear 1 and the gear 2, so as to avoid the hose being exposed to the outside and causing damage to the hose, thereby facilitating the protection of the hose and saving manpower and material resources.

[0022] 2. In the utility model, the hose is clamped inside the hose by the cooperation between the limit plate 1, the limit plate 2 and the spring, so as to avoid the separation between the hose and the guide tube when the hose is rolled up, which will cause difficulties in subsequent use.
