Description

Technical Field

[0001] This utility model relates to the field of pressure connection pipe technology, specifically an anti-detachment pressure connection pipe. Background Technology

[0002] Medical pressure connection tubing is a medical tubing specifically designed to connect medical devices, sensors, or instruments and to transmit or measure gas or liquid pressure. It transfers physiological pressure (such as blood pressure, central venous pressure, intracranial pressure, airway pressure) or pressure generated by equipment (such as the working pressure of a ventilator or anesthesia machine) from one point (such as inside the patient's body or at the device port) to another point (such as a pressure sensor, monitor, or another device).

[0003] In the prior art, Chinese patent application number CN200720068376.1 discloses a pressure extension tube connected to a pressure pump, which includes a female Luer locking connector, a soft polyvinyl chloride plastic conduit and a male Luer locking connector connected in sequence and in communication, with a soft silicone rubber sealing ring installed inside the male Luer locking connector.

[0004] Based on the above information, it can be seen that pressure connecting pipes in the prior art are generally fixed with joints (such as Luer joints) when they are connected. However, in actual use, pressure connecting pipes are generally used to convey a certain medium, so they will be subjected to greater pressure at the joint position. The pressure can easily cause the pipe and the joint to detach. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-detachment pressure connection pipe to solve the problem of the joint position falling off due to pressure mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressure connection pipe with anti-detachment features, comprising a bent section and a straight section. The front end of the straight section is fitted with a connector for connecting to medical equipment, and the inner wall of the connector has an internal thread groove. An inner liner is installed inside the connector, inserted into the inner side of the front end of the straight section. The outer surface of the inner liner is fixedly fitted with equally spaced anti-slip sleeves. A circular contact plate is fixedly installed at the front end of the inner liner, and a frustum-shaped guide platform is provided at the connection between the contact plate and the inner liner. The front end of the straight section is inserted into the connector and nested inside the inner liner. Finally, the front end of the straight section contacts and presses against the guide platform, expanding the front end of the straight section using the inclined surface of the guide platform. The contact plate and the inner wall of the connector press and fix the top of the straight section.

[0007] Preferably, a sealing ring is fixedly installed on the outer surface of the contact plate, and the sealing ring slides in contact with the inner wall of the connector.

[0008] Preferably, a ring-shaped rubber pad is fixedly installed on the side of the contact plate, and the outer surface of the rubber pad is set to a rough structure. The rubber pad is pressed against the top of the straight pipe section. When the pipeline is in use, the pressure of the internal flowing medium pushes the contact plate, and the contact plate and the inner wall of the connector clamp and fix the front end of the straight pipe section (the greater the pressure of the flowing medium, the greater the clamping force).

[0009] Preferably, a connecting rod is fixedly installed on the side of the contact plate, and the connecting rod and the connector form a through sliding structure, thereby limiting the process range of the contact plate.

[0010] Preferably, a return spring is provided on the outside of the connecting rod.

[0011] Preferably, the entire bent pipe section is configured as a flexible spiral structure.

[0012] Preferably, the inner wall of the bend section is fixedly equipped with transverse reinforcing ribs and longitudinal reinforcing ribs, and the transverse reinforcing ribs and longitudinal reinforcing ribs are combined to form a grid structure. The grid structure increases the overall strength of the bend section, thereby improving the pressure-bearing capacity of the pipeline.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the anti-detachment pressure connection pipe adopts a novel structural design, the specific details of which are as follows:

[0014] 1. The front end of the straight pipe section is inserted into the butt joint and nested on the outside of the inner liner. Finally, the front end of the straight pipe section contacts and squeezes the guide platform. The inclined surface of the guide platform expands the front end of the straight pipe section. When the pipeline is in use, the pressure of the internal flowing medium pushes the contact plate. The contact plate and the inner wall of the butt joint clamp and fix the front end of the straight pipe section (the greater the pressure of the flowing medium, the greater the clamping force), so as to prevent loosening.

[0015] Furthermore, a rubber pad is fixedly installed on the side of the contact plate. The rough surface of the rubber pad increases the friction with the front end of the straight pipe section, achieving a better clamping effect. A connecting rod that slides through the connector is also fixedly installed on the side of the contact plate, which limits the process range of the contact plate.

[0016] 2. The interior of the bend section is equipped with transverse and longitudinal reinforcing ribs. The transverse and longitudinal reinforcing ribs form a grid structure, which increases the overall strength of the bend section and thus improves the pressure-bearing capacity of the pipeline.

[0024] 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.

[0025] Example 1: To prevent pipe loosening, this example provides the following technical solution, specifically disclosed as follows: Figures 1-2 It includes a bent pipe section 1 and a straight pipe section 2. The front end of the straight pipe section 2 is equipped with a connector 3 for connecting medical equipment, and the inner wall of the connector 3 has an internal thread groove 4, such as... Figure 3 The inner side of the connector 3 is fitted with an inner liner 5 that inserts into the inner side of the front end of the straight pipe section 2, such as... Figure 5 Furthermore, anti-slip sleeves 6 are fixedly installed at equal intervals on the outer surface of the inner liner tube 5. A circular contact plate 7 is fixedly installed at the front end of the inner liner tube 5, and a frustum-shaped guide platform 8 is provided at the connection between the contact plate 7 and the inner liner tube 5. The contact plate 7 presses against the inner wall of the connector 3 to press and fix the top of the straight pipe section 2. A sealing ring 10 is fixedly installed on the outer surface of the contact plate 7, and the sealing ring 10 slides in contact with the inner wall of the connector 3. A ring-shaped rubber pad 9 is fixedly installed on the side of the contact plate 7, and the outer surface of the rubber pad 9 is set with a rough structure. The rubber pad 9 presses against the top of the straight pipe section 2, such as... Figure 4A connecting rod 11 is fixedly installed on the side of the contact plate 7, and the connecting rod 11 and the connector 3 form a through sliding structure. A return spring 12 is provided on the outside of the connecting rod 11.

[0026] When using the device, first connect one end of the straight tube 2 to the equipment that comes into contact with the patient (such as an oxygen mask), and then connect it to the medical equipment (such as a ventilator) using the internal thread groove 4 inside the connector 3. When connecting the other end of the straight tube 2 to the connector 3, first insert the straight tube 2 into the connector 3. At this time, the straight tube 2 is fitted onto the outside of the inner liner tube 5. The anti-slip sleeve 6 on the outside of the inner liner tube 5 is used to press against the inner wall of the straight tube 2 to initially prevent loosening. Then, the front end of the straight tube 2 expands under the guidance of the guide platform 8 to avoid tilting. The device utilizes the elasticity of the return spring 12 to move the connecting rod 11 outward, thereby pulling the contact plate 7. This causes the rubber pad 9 on the outer side of the contact plate 7 to compress the expanded portion at the front end of the straight pipe section 2, achieving the purpose of re-fixation. Subsequently, during use, the pressure of the internal flowing medium pushes the contact plate 7 (the contact plate 7 is equipped with a sealing ring 10 that contacts the inner wall of the connector 3 to achieve the purpose of sealing and preventing leakage), increasing the compressive force between the rubber pad 9 and the front end of the straight pipe section 2, thus achieving the purpose of the greater the pressure, the smaller the fixing effect.

[0027] Example 2: To improve the pressure-bearing strength of the pipeline, this example provides the following technical solution, specifically disclosed as follows: Figure 1 The entire bend section 1 is designed with a flexible spiral structure, such as... Figure 6 The inner wall of the bend section 1 is fixedly equipped with transverse reinforcing ribs 13 and longitudinal reinforcing ribs 14, and the transverse reinforcing ribs 13 and longitudinal reinforcing ribs 14 are combined to form a grid structure.

[0028] The interior of the bend section 1 is equipped with transverse reinforcing ribs 13 and longitudinal reinforcing ribs 14. The transverse reinforcing ribs 13 and longitudinal reinforcing ribs 14 form a grid structure. The grid structure increases the overall strength of the bend section 1, thereby improving the pressure-bearing capacity of the pipeline and preventing the pipeline from being damaged when subjected to high pressure.
