Embodiment 1

[0049] The sampling needle cleaning equipment of this embodiment is as follows: figure 1 As shown, the cleaning process of using the sampling needle cleaning device of this embodiment to clean the sampling needle is as follows: figure 2 As shown, the specific steps are as follows:

[0050] (1) Cleaning liquid enters in the cleaning tank 113 along the liquid flow channel 123 from the liquid inlet hole 121; At this moment, the positive pressure device conveys air in the cleaning tank 113 through the gas passage 143 by the air inlet 141 of the air inlet device 140 , and then the negative pressure is generated at the exhaust hole 131 by the negative pressure device of the exhaust device 130, thereby forming a stable airflow with a single direction.

[0051] (2) Put the sampling needle 100A from the needle hole 111 into the cleaning pool 113 and move up and down to clean the outer wall.

[0052] (3) After the cleaning of the outer wall is completed, the cleaning liquid stops ent...

Embodiment 2

[0054] The sampling needle cleaning equipment of this embodiment is as follows: image 3 As shown, the cleaning process of using the sampling needle cleaning device of this embodiment to clean the sampling needle is as follows: Figure 4 As shown, the specific steps are as follows:

[0055] (1) Use the negative pressure mechanism and the negative pressure device to generate negative pressure at the liquid outlet hole 215 and the exhaust hole 231 respectively, and then the cleaning liquid enters the cleaning pool 213 from the two liquid inlet holes 221 along the liquid flow channel 223 .

[0056] (2) Move the sample needle 200A from the needle hole 211 into the cleaning pool 213 and move up and down, and the cleaning liquid continues to enter the cleaning pool 213 from the two liquid inlet holes 221 along the liquid flow channel 223, and the outer wall of the sample needle 200A is completed. Cleaning; the waste liquid after the outer wall is cleaned is discharged from the liqu...

Embodiment 3

[0059] The sampling needle cleaning equipment of this embodiment is as follows: Figure 5 As shown, the cleaning process of using the sampling needle cleaning device of this embodiment to clean the sampling needle is as follows: Figure 6 As shown, the specific steps are as follows:

[0060] (1) Utilize the positive pressure device to deliver air in the cleaning tank 313 through the air inlet 341 of the air inlet device 340 through the gas passage 343, and then the negative pressure is generated through the exhaust hole 331 by the negative pressure device of the exhaust device 330 to form a direction Single steady airflow.

[0061] (2) The cleaning liquid enters the cleaning tank 313 from the liquid inlet hole 321 along the liquid flow channel 323 , and the waste liquid flows out from the liquid outlet hole 315 .

[0062] (3) Enter the sampling needle 300A into the cleaning tank 313 from the needle hole 311, and move up and down in the cleaning tank 313; at this time, the cl...

Abstract

The invention relates to a cleaning device for a sampling needle and a cleaning method and application of the sampling needle. The sampling needle cleaning equipment includes a cleaning device, a liquid inlet device and an exhaust device. The cleaning device includes a needle hole, a cleaning pool and a liquid outlet hole. The cleaning device can accommodate the feeding and cleaning of the sampling needle; the liquid inlet device includes a liquid inlet hole and the liquid flow channel, the liquid flow channel communicates with the cleaning tank and the included angle is an acute angle, the liquid inlet device can deliver the cleaning liquid to the cleaning tank of the cleaning device; the exhaust device includes a gas flow channel, an exhaust hole and a negative pressure device, and the gas communication The connection between the gas channel and the cleaning pool is close to the liquid outlet, the connection between the liquid flow channel and the cleaning pool is close to the needle hole, and the exhaust device can form a pressure difference inside the cleaning pool. The above cleaning device for the sample needle can overcome the problem that the cleaning solution is easy to overflow from the needle hole during the process of cleaning the sample needle.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a cleaning device for a sampling needle and a method and application for cleaning the sampling needle. Background technique [0002] The sampling needle is an important part of the sample analysis equipment. In order to ensure the accuracy of the analysis results and reduce the carryover between samples, the sampling needle is required to be cleaned in time after sampling and sample addition. Only then can the next sampling and adding action be carried out. In the process of cleaning the sample needle with the traditional sample needle cleaning equipment, the cleaning liquid is easy to overflow from the needle hole, resulting in incomplete cleaning. Contents of the invention [0003] Based on this, it is necessary to provide a cleaning device for a sample needle to address the problem that the cleaning solution is likely to overflow from the needle hole during the cleaning proce...
