Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a ventilator tubing with a movable water collection cup. Background Technology

[0002] Mechanical ventilation is the most timely and effective treatment for respiratory failure caused by various reasons, and it is widely used in respiratory medicine, thoracic surgery, emergency departments, intensive care units, operating rooms, geriatric wards, and infectious disease wards. During mechanical ventilation, continuous humidification is required to prevent airway dryness, airway mucosal damage, and the drying and difficulty in expelling sputum crusts. However, humidified air and the patient's exhaled air contain a significant amount of water vapor, which condenses as it passes through the ventilator circuit. Chinese patent application CN202421047931.2 discloses a backflow prevention condensate collection cup for respiratory tubing, comprising a collection cup body and an inlet pipe disposed on the collection cup body. The collection cup body collects condensate, and the inlet pipe allows condensate from the ventilator tubing to flow into the collection cup body. An anti-backflow device is located below the inlet pipe, enabling one-way passage.

[0003] Although the water collection cup achieves backflow prevention, in clinical practice, because the water collection cup is usually lightweight, it is easily affected by external environmental interference and its position may change. When the water collection cup is tilted or even inverted and its position is higher than the position of the ventilator tubing, it will be difficult to collect water. Therefore, we propose a ventilator tubing with a movable water collection cup to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a ventilator tubing with a movable water collection cup to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ventilator tubing with a movable water collection cup, comprising a corrugated telescopic tube, with connectors fixedly connected to both ends of the corrugated telescopic tube, and fixing rings fixedly sleeved on both sides of the corrugated telescopic tube. The outer wall of the middle portion of the fixing rings is fixedly connected to both ends of a metal strip, and a movable ring is movably sleeved on the metal strip. One end of the movable ring is connected to a positioning bolt via a threaded structure. One end of a connecting strip is fixedly connected to both outer walls of the movable ring, and the other end of the connecting strip is fixedly connected to both outer walls of a second fixing ring. The second fixing ring is fixedly sleeved on the outside of the connecting tube. One end of the connecting tube is fixedly connected to the middle portion of the corrugated telescopic tube, and the other end of the connecting tube is fixedly connected to one end of an anti-reverse assembly. The other end of the anti-reverse assembly is fixedly connected to a connecting cap, and the connecting cap is connected to a water collection cup via a threaded structure.

[0006] Preferably, an air valve is fixedly installed on one side of the connecting cap.

[0007] Preferably, both the metal strip and the connecting strip have a U-shaped structure, and the connecting strip is symmetrically arranged.

[0008] Preferably, the inner diameter of the movable ring is larger than the outer diameter of the metal strip.

[0009] Preferably, the anti-reverse assembly includes a cylinder, a water-receiving ring, a ball, a spring, and a support ring. One end of the cylinder is fixedly connected to the end of the connecting pipe. The water-receiving ring is fixedly sleeved on the side of the cylinder closest to the connecting pipe. The water-receiving ring moves and abuts against the ball. The side of the ball away from the water-receiving ring abuts against one end of the connecting spring. The other end of the spring is fixedly abuts against the connecting support ring. The support ring is fixedly sleeved on the inner wall of the other end of the cylinder.

[0010] Preferably, the inner diameter of the water-receiving ring is smaller than the diameter of the sphere.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by extending and retracting the corrugated expansion tube, the position of the connecting tube is changed, thereby adjusting the position of the water collection cup, making it convenient to adjust the water collection cup to a suitable position for use. At the same time, the rigidity of the metal strip, together with the connecting strip, prevents the water collection cup from tilting or inverting, ensuring the water collection effect; and the anti-reverse component prevents water from flowing back into the water collection cup.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1

[0017] Reference Figure 1 ,2 This is the first embodiment of the present invention. This embodiment provides a ventilator tubing with a movable water collection cup, including a corrugated telescopic tube 1. Connecting heads 2 are fixedly connected to both ends of the corrugated telescopic tube 1. Fixing rings 3 are fixedly sleeved on both sides of the corrugated telescopic tube 1. The outer walls of the middle part of the fixing rings 3 are fixedly connected to both ends of a metal strip 4. A movable ring 5 is movably sleeved on the outside of the metal strip 4. A positioning bolt 6 is connected to one end of the movable ring 5 through a threaded structure. One end of a connecting strip 7 is fixedly connected to the outer walls of both sides of the movable ring 5. The other end of the connecting strip 7 is fixedly connected to the outer walls of the two fixing rings 9. The two fixing rings 9 are fixedly sleeved on the outside of a connecting tube 8. One end of the connecting tube 8 is fixedly connected to the middle part of the corrugated telescopic tube 1. The other end of the connecting tube 8 is fixedly connected to one end of an anti-reverse component 10. The other end of the anti-reverse component 10 is fixedly connected to a connecting cap 11. A water collection cup 13 is connected to the connecting cap 11 through a threaded structure.

[0018] Connect the connector 2 to the ventilator tubing. When the position of the water collection cup 13 needs to be adjusted, manually loosen the positioning bolt 6 so that the end of the positioning bolt 6 is disengaged from the metal strip 4, allowing the movable ring 5 to move along the length of the metal strip 4. After the movable ring 5 moves, it drives the fixed connecting strip 7 to move synchronously. The connecting strip 7 is made of metal, which can smoothly drive the fixed ring 9 to move synchronously. The fixed ring 9 drives the fixed connecting tube 8 to move, and the connecting tube 8 stretches one side of the corrugated telescopic tube 1 while compressing the other side. After the water collection cup 13 is adjusted to the appropriate position, manually tighten the positioning bolt 6. The end of the positioning bolt 6 abuts against the outer wall of the metal strip 4, thereby limiting and fixing the position of the movable ring 5. After the position of the movable ring 5 is fixed, the connecting strip 7 keeps the position of the connecting tube 8 fixed, thus fixing the position of the water collection cup 13. When collecting water, the water source enters the anti-reverse component 10 through the connecting tube 8, and then enters the water collection cup 13 for collection.

[0019] Example 2

[0020] Reference Figure 1-2 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, an air valve 12 is fixedly installed on one side of the connecting cap 11. The air valve 12 is set so that water can smoothly enter the water collection cup 13 and maintain pressure balance.

[0021] Specifically, both metal strip 4 and connecting strip 7 have a U-shaped structure, and connecting strip 7 is symmetrically arranged.

[0022] Specifically, the inner diameter of the movable ring 5 is larger than the outer diameter of the metal strip 4, which facilitates the adjustment and movement of the movable ring 5 outside the metal strip 4.

[0023] Specifically, the anti-reverse assembly 10 includes a cylinder 101, a water-receiving ring 102, a ball 103, a spring 104, and a support ring 105. One end of the cylinder 101 is fixedly connected to the end of the connecting pipe 8. The water-receiving ring 102 is fixedly sleeved inside the cylinder 101 on the side closest to the connecting pipe 8. The water-receiving ring 102 moves and abuts against the ball 103. The side of the ball 103 away from the water-receiving ring 102 abuts against one end of the connecting spring 104. The other end of the spring 104 is fixedly abuts against the connecting support ring 105. The support ring 105 is fixedly sleeved on the inner wall of the other end of the cylinder 101.

[0024] Furthermore, the inner diameter of the water receiving ring 102 is smaller than the diameter of the sphere 103. During water collection, the water source enters the cylinder 101 of the anti-reverse assembly 10 through the connecting pipe 8. The water pressure compresses the spring 104, causing the sphere 103 to disengage from the water receiving ring 102, thus creating a certain gap between the water receiving ring 102 and the sphere 103. Since the diameter of the sphere 103 is smaller than the inner diameter of the cylinder 101, the water source passes through the cylinder 101 and enters the water collecting cup 13 for collection. At the same time, under the elastic force of the spring 104, the sphere 103 engages with the water receiving ring 102 to prevent the water source in the water collecting cup 13 from flowing back.

[0025] Example 3

[0026] Reference Figure 1-2 This is the third embodiment of the present invention. Based on the previous two embodiments, in use, it is connected to the ventilator tubing via connector 2. When the position of the water collection cup 13 needs adjustment, the positioning bolt 6 is manually loosened, causing the end of the positioning bolt 6 to disengage from the metal strip 4. This allows the movable ring 5 to move along the length of the metal strip 4. After the movable ring 5 moves, it drives the fixed connecting strip 7 to move synchronously. The connecting strip 7 is made of metal, which in turn allows it to smoothly drive the fixed ring 9 to move synchronously. The fixed ring 9 drives the fixed connecting tube 8 to move, causing the connecting tube 8 to stretch one side of the corrugated telescopic tube 1 while compressing the other side. When the water collection cup 13 is adjusted to the appropriate position, the positioning bolt 6 is manually tightened. The end of the positioning bolt 6 then... The metal strip 4 contacts the outer wall, thereby limiting and fixing the position of the movable ring 5. After the position of the movable ring 5 is fixed, the connecting strip 7 cooperates to keep the position of the connecting pipe 8 fixed, thereby fixing the position of the water collecting cup 13. When collecting water, the water source enters the cylinder 101 of the anti-reverse component 10 through the connecting pipe 8. The water source pressure compresses the spring 104, and at the same time, the ball 103 is separated from the water receiving ring 102, thereby creating a certain gap between the water receiving ring 102 and the ball 103. The diameter of the ball 103 is smaller than the inner diameter of the cylinder 101, allowing the water source to pass through the cylinder 101 and enter the water collecting cup 13 for collection. At the same time, under the elastic force of the spring 104, the ball 103 cooperates with the water receiving ring 102 to prevent the water source in the water collecting cup 13 from flowing back.

[0027] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial improvements made to this utility model using this concept should be considered as infringing on the protection scope of this utility model.
