Problems solved by technology

However, due to the various sizes and specifications of the straws and the different diameters of the end openings, it is not easy to match with the suction end of the ear washing ball, which is very inconvenient to use and seriously affects the accuracy of sample suction.
In addition, in the prior art, when using a straw and an ear wash ball for sample suction operation, one hand needs to hold the straw, and the other hand operates the ear wash ball. Moreover, both hands need to cooperate closely, which makes the operation very difficult and reduces the working efficiency. low

Embodiment 1

[0029] see figure 1 with figure 2 , a suction pipe self-adaptive joint, including a port assembly, a plurality of card tube assemblies 21 connected under the port assembly and a guide port assembly 23 connected under the card tube assembly 21. The port assembly includes a port body 201 with an upper port 202 and a lower port 203 and a port ferrule 205 disposed in the lower port 203 . see Figure 7 , the self-adaptive joint 2 cooperates with the ear washing ball 1 and the positioning bracket 3 to form a straw device that can be operated with one hand. The upper port 202 is in the shape of an inverted cone, and fits with the suction port 12 of the ear washing ball 1 . The lower port 203 is roughly drum-shaped. The top end of the lower port 203 is provided with a flow hole communicating with the tip of the upper port 202 . The ear cleaning ball 1 is provided with a spherical upper air bag 11 and a tapered suction port 12 extending smoothly from the air bag 11 .

Embodiment 2

[0039] This embodiment is the same as the first embodiment except that the connection structure between the tube assembly 21 and the port assembly and the tube assembly 21 is different.

[0040] see Figure 11 , Figure 12 with Figure 13 , in this embodiment, the connection structure between the card tube assemblies 21 includes the serial connection holes 218 that pass through the upper half body 212 and the lower half body 213 on the card tube module 211 in the card tube assembly 21 and pass through The serial hole 218 is connected to the connecting rod 217 on the T-shaped slot 204 of the port assembly. Further, the self-adaptive joint 1 includes a guide port assembly 23 connected to the lower end of the tube assembly 21 . In this embodiment, the port module 231 of the port assembly 23 is also provided with a series connection hole 218, and the connecting rod 217 passes through the port assembly 23 and the series connection hole 218 of the card tube assembly 21 and then c...

Abstract

The invention discloses a sucker self-adaptive adaptor. The sucker self-adaptive adaptor comprises a clamping pipe assembly and at least one group of port assemblies, wherein the clamping pipe assembly comprises an elastic ring and a plurality of clamping pipe modules which are circumferentially spliced and separately connected with the elastic ring; the elastic ring is protruded out of an annularspace formed by encircling the clamping pipe modules; each port assembly comprises a port main body and a port clamping sleeve; the port main body is provided with an upper port and a lower port; theport clamping sleeve is a rotating elastic body and is provided with a throat portion and an inlet which is gradually increased in an arc manner from an opening of the throat portion; the clamping pipe assemblies are movably arranged on the lower end of the port assembly in a radial radiation manner; and the port elastic sleeve is arranged in the lower port and positioned between the port assembly and the clamping pipe assembly. According to the technical scheme, a plurality of clamping pipe modules are circumferentially spliced to form a structure connected with the elastic ring, so that a sucker suitable for different pipe diameters is inserted, the sucker can be fixed, the upper port of the sucker is arranged in the port clamping sleeve in a clamping manner so as to form effective sealing with a sucker end of an ear washing bulb.

Description

technical field [0001] The invention relates to a sample suction device used in a laboratory, in particular to a self-adaptive connector for suction pipes used to match different pipe diameters with ear washing balls. Background technique [0002] When obtaining non-trace samples in some medical tests, the method of using a straw and ear washing ball is usually used. However, due to the many sizes and specifications of the suction pipes and the different diameters of the end openings, it is not easy to match with the suction end of the ear washing ball, which is very inconvenient to use and seriously affects the accuracy of sample absorption. In addition, in the prior art, when using a straw and an ear wash ball for sample suction operation, it is necessary to hold the straw with one hand and operate the ear wash ball with the other hand, and both hands need to cooperate closely, so the operation is very difficult and the work efficiency is low. low. Therefore, there is an...
