Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and in particular to the technical field of negative pressure drainage balls. Background Technology

[0002] Sterile silicone negative pressure drainage balls are medical devices primarily used for negative pressure drainage therapy. Made of medical-grade silicone material, these balls possess excellent softness and biocompatibility. They are widely used in surgical procedures, trauma care, and breast cancer surgery to effectively drain wound exudate and promote wound healing.

[0003] Existing negative pressure drainage balls have their drainage port directly connected to the drainage tube. For example, a novel negative pressure drainage ball disclosed in CN22193674U has its drainage inlet directly connected to the silicone connecting tube drainage tube. In actual use, the part of the drainage tube near the negative pressure drainage ball is prone to folding, which can lead to blockage of the drainage tube and prevent the negative pressure drainage ball from draining smoothly. At the same time, existing negative pressure drainage balls require nursing staff or patients to pay attention to whether there is too much fluid inside the drainage ball. If they forget to check for various reasons, the drainage ball may become full of fluid, at which point the negative pressure drainage ball can no longer drain, and there may even be backflow of the drained fluid, which can easily lead to safety hazards. In addition, existing negative pressure drainage balls are not easy to fix and are prone to sliding, shaking, or falling off. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the existing technology by proposing an intelligent fixed anti-folding negative pressure drainage ball. This ball can remotely remind nursing staff or patients in a timely manner when the internal fluid is almost full, and it can maintain the passage and is not easily blocked.

[0005] To achieve the above objectives, this utility model proposes an intelligent fixed anti-folding negative pressure drainage ball, comprising a negative pressure drainage ball body, a corrugated tube, and an infrared liquid level sensor. The top of the negative pressure drainage ball body is connected to a corrugated tube, which is connected to the interior of the negative pressure drainage ball body. An infrared liquid level sensor is fixed to the outside of the negative pressure drainage ball body. The probe of the infrared liquid level sensor passes through the wall of the negative pressure drainage ball body and is inserted into the interior of the negative pressure drainage ball body. The infrared liquid level sensor is connected to a Bluetooth module and includes an indicator light.

[0006] Preferably, the corrugated pipe consists of a PVC corrugated outer pipe and a TPU inner pipe, with the TPU inner pipe located inside the corrugated pipe and the PVC corrugated outer pipe located outside the corrugated pipe.

[0007] Preferably, the end of the corrugated pipe is connected to the drainage pipe via a Luer connector.

[0008] Preferably, the indicator light is a red LED indicator light, which lights up when the infrared liquid level sensor detects that the liquid level inside the negative pressure drainage ball is too high.

[0009] Preferably, the negative pressure drainage ball has elastic straps on both sides, with magnetic strips embedded inside the elastic straps and a medical-grade PVC coating covering the magnetic strips. The two elastic straps are respectively equipped with a female and a female Velcro fastener. The ends of the elastic straps are fitted with detachable magnetic buckles with magnetic adsorption surfaces.

[0010] The beneficial effects of this utility model are as follows: By fixing an infrared liquid level sensor to the body of the negative pressure drainage ball, the liquid level inside the ball can be detected in real time, which can promptly remind nursing staff or patients when the liquid is almost full, making it safer to use; the corrugated tube design makes it less prone to folding, effectively ensuring the unobstructed flow of the tubing connected to the negative pressure drainage ball, ensuring that the negative pressure drainage ball can continuously perform its drainage function, making it more reliable to use.

[0011] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

Detailed Implementation

[0017] Example 1:

[0018] See Figure 1This utility model relates to an intelligent fixed anti-folding negative pressure drainage ball, which includes a negative pressure drainage ball body 1, a corrugated pipe 2, and an infrared liquid level sensor 3. The top of the negative pressure drainage ball body 1 is connected to a corrugated pipe 2, which is connected to the inside of the negative pressure drainage ball body 1. The negative pressure drainage ball body 1 has an exhaust port with a sealing plug near the top and a sewage outlet with a sealing plug at the bottom.

[0019] The end of the corrugated pipe 2 is connected to the drainage pipe 26 via a Luer connector 25.

[0020] See Figure 3 The corrugated pipe 2 is composed of a PVC corrugated outer pipe 21 and a TPU inner pipe 22. The TPU inner pipe 22 is located inside the corrugated pipe 2, and the PVC corrugated outer pipe 21 is located outside the corrugated pipe 2.

[0022] The inner diameter of the TPU inner tube 22 is 4mm.

[0023] See Figure 1 , Figure 4 An infrared liquid level sensor 3 is fixed to the outside of the negative pressure drainage ball 1. The probe 30 of the infrared liquid level sensor 3 passes through the ball wall of the negative pressure drainage ball 1 and is inserted into the inside of the negative pressure drainage ball 1. The infrared liquid level sensor 3 is connected to a Bluetooth module and is connected to the background device via the Bluetooth module. The infrared liquid level sensor 3 includes an indicator light 31 and is equipped with a battery for powering the infrared liquid level sensor 3, the Bluetooth module, and the indicator light 31.

[0024] The infrared liquid level sensor 3 can be model E18-D80NK, and the Bluetooth module can be Zhongke Lanxun AB32VG1.
