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 straw self-adapting joint, including a port assembly 20, multiple sets of clamping tube assemblies 21 connected under the port assembly 20, and a guide port assembly 23 connected under the clamping tube assembly 21. The port assembly 20 includes a port body 201 provided with an upper port 202 and a lower port 203 and a port card sleeve 205 provided in the lower port 203. See Figure 7 , The self-adapting joint 2 cooperates with the ear wash ball 1 and the positioning bracket 3 to form a single-handed straw device. The upper port 202 has an inverted cone shape and is adapted to the suction end 12 of the ear wash ball 1. The lower port 203 has a substantially drum shape. 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 wash ball 1 is provided with an upper air bag 11 having a spherical shape and a suction mouth end 12 extending smoothly from the air bag 11 in a conical...

Embodiment 2

[0039] This embodiment is the same as the first embodiment except that the connection structure between the clamping tube assembly 21 and the port assembly 20 and the clamping tube assembly 21 is different.

[0040] See Picture 11 , Picture 12 with Figure 13 In this embodiment, the connection structure between the clamping tube assembly 21 includes a series connection hole 218 that penetrates the upper half body 212 and the lower half body 213 provided on the clamping tube module 211 in the clamping tube assembly 21, and passes through The series connection hole 218 is connected to the connecting rod 217 on the T-shaped groove 204 of the port assembly 20. Further, the self-adapting joint 1 includes a guide port assembly 23 connected to the lower end of the clamping tube assembly 21. In this embodiment, the guide port module 231 of the guide port assembly 23 is also provided with a series connection hole 218, and the connecting rod 217 passes through the guide port assembly 23...

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 suction tube self-adapting joint used for adapting different tube diameters with ear wash balls. Background technique [0002] In some medical tests, when non-micro samples are obtained, a straw is usually used in combination with an ear ball. However, due to the large size of the straws and the different diameters of the end openings, it is not easy to match the suction end of the ear wash bulb, and it is inconvenient to use, which seriously affects the accuracy of sample extraction. In addition, in the prior art, when a pipette plus an ear ball is used for sample suction operation, it is necessary to hold the pipette with one hand and operate the ear ball with the other hand. In addition, the hands need to be closely matched, which makes the operation very difficult and work efficiency. low. Therefore, there is an urgent need for a device that can quickly and stabl...
