Abstract

The utility model provides an explosion-proof composite pipe for a medical water jet scalpel. The explosion-proof composite pipe comprises an inner pipe, and a woven reinforcing layer, a protective layer and a high-temperature-resistant layer which are sequentially arranged on the outer side of the inner pipe from inside to outside, the inner pipe is made of a nylon material; the woven reinforcing layer is made of a bulletproof fiber material; the protective layer is made of a TPU (Thermoplastic Polyurethane) material; according to the design, the bulletproof fiber material is adopted as the woven reinforcing layer to be arranged on the outer side of the inner pipe, the explosion-proof capacity of the inner pipe is greatly improved, the protective layer made of the TPU material is arranged outside the woven reinforcing layer for protection, and the TPU protective layer has the characteristics of high elasticity, high tear resistance and the like and is arranged on the outer side of the woven reinforcing layer, so that the explosion-proof capacity of the inner pipe is greatly improved. The high-temperature-resistant layer is additionally arranged on the outer side of the woven reinforcing layer for protection due to the fact that the high-temperature-resistant performance of the TPU material is low, and the bursting pressure of the composite pipe can meet 36250 PSI.

Description

Technical Field

[0001] This utility model relates to the field of water pipe technology, and in particular to an explosion-proof composite pipe for medical water jets. Background Technology

[0002] Medical water jets are used for wound debridement (acute and chronic wounds, burns), soft tissue debridement, etc., and have unique application advantages and clinical value. Because the maximum water jet velocity of a medical water jet is close to Mach 2, and the water jet diameter is approximately 0.1 mm, the water jet head adopts a dual-pump design. It uses a precisely controllable high-speed water jet to act on the intended treatment area, breaking down necrotic, infected tissue, and contaminants. Combined with the Venturi effect, the power is stronger, and the debridement and abrasion are more precise, achieving the goal of precision treatment. Currently, one medical water jet has a water jet pressure range of... Pressure control accuracy of ±5% requires the pipe to have a burst pressure of 36250 PSI (2500 kg), but current pipes cannot meet this requirement. Utility Model Content

[0003] The purpose of this invention is to provide an explosion-proof composite tube for medical water jet injection to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An explosion-proof composite tube for medical water jets includes an inner tube and, from the inside out, a braided reinforcing layer, a protective layer, and a high-temperature resistant layer disposed on the outer side of the inner tube; the inner tube is made of nylon material; the braided reinforcing layer is made of bulletproof fiber material; and the protective layer is made of TPU material.

[0006] In a further description of this utility model, the high-temperature resistant layer is made of TPEE material.

[0007] In a further description of this utility model, the high-temperature resistant layer is made of PTFE material.

[0008] The beneficial effects of this utility model are as follows:

[0009] This design uses bulletproof fiber material as a braided reinforcement layer on the outside of the inner tube, which greatly improves the explosion-proof capability of the inner tube. In addition, a TPU material protective layer is set outside the braided reinforcement layer for protection. The TPU protective layer has high elasticity and high tear resistance, and is set outside the braided reinforcement layer to provide good protection. Since the high temperature resistance of TPU material is relatively low, a high temperature resistant layer is added outside it for protection. The burst pressure of the composite pipe designed in this way can meet 36250 PSI. Attached Figure Description

[0010] Figure 1This is a partial structural diagram of the present invention. Detailed Implementation

[0011] The present invention will be further described below with reference to the accompanying drawings:

[0012] like Figure 1 As shown, a medical water jet explosion-proof composite tube includes an inner tube 1 and, from the inside out, a braided reinforcing layer 2, a protective layer 3, and a high-temperature resistant layer 4 sequentially disposed on the outer side of the inner tube 1. The inner tube 1 is made of nylon material; the braided reinforcing layer 2 is made of bulletproof fiber material; and the protective layer 3 is made of TPU material. This design uses bulletproof fiber material as the braided reinforcing layer 2 on the outer side of the inner tube 1, which greatly improves the explosion-proof capability of the inner tube 1. Furthermore, a TPU material protective layer 3 is disposed on the outer side of the braided reinforcing layer 2 for protection. The TPU protective layer 3 has high elasticity and high tear resistance properties, and is disposed on the outer side of the braided reinforcing layer 2, providing good protection for the braided reinforcing layer 2. Since the high-temperature resistance of TPU material is relatively low, a high-temperature resistant layer 4 is added on its outer side for protection. The burst pressure of this composite tube design can meet 36250 PSI.

[0013] The high-temperature resistant layer 4 can be made of high-temperature resistant materials such as TPEE or PTFE. In this embodiment, TPEE material is selected.

[0014] The above description is not intended to limit the technical scope of this invention. Any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this invention shall still fall within the scope of the technical solution of this invention.
