Embodiment 1

[0025] A negative pressure drainage ball with a pressure test, such as figure 1 As shown, it includes a negative pressure ball 1, one end of the pressure ball 1 is provided with a three-way connecting pipe 2, the three-way connecting pipe 2 is integrally formed, and the end of the three-way connecting pipe 2 away from the negative pressure ball 1 is provided with a drainage tube 3.

[0026] In this embodiment, the negative pressure ball 1 is made of PVC material. PVC has been used as a medical material for many years. It has chemical corrosion resistance, strong resistance to oxidants, reducing agents and strong acids, and is wear-resistant. It is easy to produce, safe to use and low in cost.

[0027] Such as figure 2 As shown, the outer surface of the negative pressure ball 1 is provided with several anti-slip belts 13, the end of the negative pressure ball 1 close to the three-way connecting pipe 2 is connected with an air outlet pipe 16, and the outer end of the negative ...

Embodiment 2

[0033] During use, long-term use of the negative pressure ball 1 will lead to collapse, which will reduce the effect of negative pressure when the hand is pressed and affect the drainage effect. Therefore, we make improvements to the negative pressure ball 1 on the basis of Example 1, such as Figure 4 As shown, the interior of the negative pressure ball 1 is symmetrically provided with two support pieces 14, the support pieces 14 are arranged in a vertical arc, and several springs 15 are arranged between the support pieces 14 and the inner wall of the negative pressure ball 1, and the support pieces 14 Several through holes 141 are opened on the surface.

[0034] Specifically, one end of the spring 15 is tightly welded with the supporting sheet 14, and the inner wall of the negative pressure ball 1 at the other end of the spring 15 is tightly welded.

[0035] In this embodiment, the support piece 14 is made of copper material, which has certain flexibility and can support the...

Abstract

The invention relates to the technical field of negative pressure balls, in particular to a negative pressure drainage ball with pressure testing. The negative pressure drainage ball comprises a negative pressure ball. A three-way connecting pipe is arranged at one end of the negative pressure ball. A drainage pipe is arranged at the end, away from the negative pressure ball, of the three-way connecting pipe, an air outlet pipe is connected to the end, close to the three-way connecting pipe, of the negative pressure ball, the three-way connecting pipe comprises a main pipe, one end of the mainpipe is in threaded connection with the air outlet pipe, the other end of the main pipe is in pluggable fit with the drainage pipe, a pressure measuring pipe is perpendicularly arranged on the surface of the middle of the main pipe, the end, away from the main pipe, of the pressure measuring pipe is a threaded end, a connecting pipe is in threaded connection with the threaded end, a pressure gauge is connected to the end, away from the threaded end, of the connecting pipe, the negative pressure drainage ball is simple in structure and convenient to use, the pressure meter and the pressure measuring pipe can measure pressure inside the negative pressure ball at any time, and therefore precise regulation of the measuring box is convenient, a supporting piece and a spring can ensure that nocollapse is caused when the negative pressure ball is pressed for a long time, negative pressure regulation is performed more precisely, and the drainage effect is ensured.

Description

technical field [0001] The invention relates to the technical field of drainage balls, in particular to a negative pressure drainage ball with pressure test. Background technique [0002] Negative pressure drainage will use a negative pressure drainage ball, and sometimes doctors will use full negative pressure or half negative pressure according to the drainage, which is not easy to control and measure. There is a lack of a negative pressure drainage ball for stress testing on the market. In addition, in When performing negative pressure drainage, long-term pressing of the negative pressure ball will cause the structure to collapse, and the original shape cannot be restored well, thus affecting the drainage effect. In view of this, we propose a negative pressure drainage ball with pressure test. Contents of the invention [0003] The purpose of the present invention is to provide a negative pressure drainage ball with a pressure test to solve the problem of lack of a pres...
