Description

Technical Field

[0001] The invention belongs to the field of mechanical technology and relates to a novel test tube type cleaning container. Background Art

[0002] The probe of biochemical analyzer is one of the key components of biochemical analyzer, which is used to accurately absorb and transfer samples or reagents. The design and performance of the probe directly affect the accuracy and reliability of the analysis results.

[0003] Probe cleaning is a key step to ensure analytical accuracy and avoid cross contamination. Currently, biochemical analyzers on the market usually use fixed-position cleaning containers to clean the probes by immersing them in cleaning fluid.

[0004] This design has several obvious disadvantages:

[0005] Probe cleaning is a key step to ensure analytical accuracy and avoid cross contamination. However, existing probe cleaning methods have some disadvantages:

[0006] 1. Incomplete cleaning: Some cleaning methods may not completely remove the residue on the probe surface, especially for viscous samples or samples with high protein content. This incomplete cleaning may cause cross-contamination between samples and affect subsequent test results.

[0007] 2. Cleaning agent residue: When using chemical cleaning agents to clean the probe, if the rinse is not sufficient, the cleaning agent itself may remain on the probe surface, which may also affect the test results of the sample.

[0008] 3. Time and resource consumption: Traditional cleaning methods often require a long time and a large amount of cleaning solution, which not only increases the complexity of the operation but also increases the cost of the experiment.

[0009] 4. Equipment wear: Frequent cleaning may cause probe wear, especially when using some rough cleaning methods, such as mechanical scrubbing. This wear may affect the service life of the probe and the accuracy of the test.

[0010] 5. Cleaning efficiency: For rapid testing or large-scale sample analysis, existing cleaning methods may not meet high efficiency requirements, affecting overall work efficiency.

[0011] 6. Environmental impact: Using large amounts of chemical cleaning agents not only increases costs, but can also have a negative impact on the environment, especially when these chemicals are discharged into the environment without proper treatment.

[0012] In view of the above shortcomings, researching and developing new probe cleaning methods that are more efficient, environmentally friendly, low-cost and less wear-prone to equipment is an important current research direction. Summary of the invention

[0013] The object of the present invention is to provide a novel test tube type cleaning container with high stability and compact structure in view of the above problems existing in the prior art.

[0014] The purpose of the numbing sensation can be achieved through the following technical solutions:

[0015] A new type of test tube type cleaning container is characterized in that it includes a long tubular body, the upper end of the tube body is open, the lower end of the tube body has a liquid outlet communicated with its inner cavity, and also includes a liquid inlet obliquely arranged at the side wall of the tube body. The number of the liquid inlets is several, and the several liquid inlets are arranged along the axial direction of the tube body. The liquid outlet has an interface structure that can be connected to an air pump.

[0016] In the above-mentioned new test tube type cleaning container, the liquid outlet includes a cannula and a sealing sleeve. The cannula is inserted into the tube body. A positioning structure is provided between the cannula and the tube body. Under the action of the positioning structure, the cannula and the tube body can be positioned and the sealing sleeve can be stably positioned between the connection between the cannula and the tube body.

[0017] In the above-mentioned new test tube type cleaning container, the inner end of the insert tube has a protruding retaining edge, and the outer end of the insert tube is threadedly connected with a locking nut. The retaining edge and the locking nut are respectively against the inner and outer walls of the tube body, and the sealing sleeve is sleeved on the insert tube and is tightly pressed between the outer side of the tube body and the locking nut.

[0018] In the above-mentioned novel test tube type cleaning container, the retaining edge and the inserting tube are an integrated structure.

[0019] In the above-mentioned novel test tube type cleaning container, the retaining edge is in contact with the inner wall surface of the tube body.

[0020] In the above-mentioned novel test tube type cleaning container, the outer end of the sealing sleeve contacts the locking nut surface, and the inner end of the sealing sleeve has an inclined contact surface, and the contact surface contacts the outer side surface of the tube body.

[0021] In the above-mentioned novel test tube type cleaning container, the sealing sleeve is made of flexible material.

[0022] In the above-mentioned novel test tube type cleaning container, the sealing sleeve is made of rubber material.

[0023] In the above-mentioned novel test tube type cleaning container, the interface structure is fixedly connected to a connecting pipe with external threads at the lower end of the tube body, and the connecting pipe is communicated with the inner cavity of the tube body.

[0024] In the above-mentioned novel test tube type cleaning container, the inner diameter of the opening at the upper end of the tube body is smaller than the inner diameter of the tube body.

[0025] Compared with the prior art, the novel test tube type cleaning container has a probe that gradually translates relative to the tube body after being embedded in the cleaning mechanism. Therefore, the cleaning liquid introduced from the liquid inlet can stably clean various parts of the probe. Since there are several liquid inlets, the cleaning stability of the probe can be further improved.

[0026] Of course, the cleaning liquid input from the liquid inlet will eventually be discharged from the liquid outlet stably and smoothly.

[0027] At the same time, a plurality of liquid inlets are evenly distributed on the outside of the tube body, and the structure of the entire cleaning mechanism is relatively compact, and has high practical value. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] It should be noted that when a component is referred to as being "mounted on" another component, it may be directly mounted on the other component or there may be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a central component at the same time. When a component is considered to be "fixed to" another component, it may be directly fixed on the other component or there may be a central component at the same time.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0033] like Figure 1As shown, the new test tube type cleaning container includes a tube body 1 in the shape of a long tube, the upper end of the tube body 1 is open, the lower end of the tube body 1 has a liquid outlet 1a connected to its inner cavity, and also includes a liquid inlet obliquely arranged at the side wall of the tube body 1. The number of the liquid inlets is several, and the several liquid inlets are arranged along the axial direction of the tube body 1. The liquid outlet has an interface structure that can be connected to an air pump.

[0034] The cleaning liquid stably enters the tube body 1 through the liquid inlet. Since the liquid inlet and the tube body 1 are inclined, the cleaning liquid output in the inclined direction forms a relative motion with the probe moving upward relative to the tube body 1, thereby being able to stably clean various parts of the probe.

[0035] Of course, during the cleaning process, the cleaning liquid accumulated in the tube body 1 will be stably discharged from the liquid outlet 1a.

[0036] After the above cleaning operation is completed, the interface structure is connected to the air pump, and the residual cleaning liquid in the tube body 1 and the outside of the probe can be adsorbed and completely removed under the action of negative pressure.

[0037] The liquid outlet 1a includes a cannula 2 and a sealing sleeve 3. The cannula 2 is inserted into the tube body 1. A positioning structure is provided between the cannula 2 and the tube body 1. Under the action of the positioning structure, the cannula 2 and the tube body 1 can be positioned and the sealing sleeve 3 can be stably positioned between the connection between the cannula 2 and the tube body 1.

[0038] Under the action of the positioning structure, the cannula 2 is stably connected to the side of the tube body 1 . Of course, under the action of the sealing sleeve 3 , the sealing performance of the connection between the cannula 2 and the tube body 1 can be effectively improved.

[0039] The inner end of the insert tube 2 has a protruding retaining edge 2a, and the outer end of the insert tube 2 is threadedly connected with a locking nut 4. The retaining edge 2a and the locking nut 4 are respectively against the inner and outer walls of the tube body 1. The sealing sleeve 3 is sleeved on the insert tube 2 and is tightly pressed between the outer side of the tube body 1 and the locking nut 4.

[0040] The locking nut 4 and the retaining edge 2a respectively abut against the inner wall and the outer wall of the tube body 1. This structure can eventually stably connect the insert tube 2 to the tube body 1. The sealing sleeve 3 seals the connection between the insert tube 2 and the tube body 1.

[0041] The retaining edge 2a and the insertion tube 2 are an integrated structure.

[0042] The retaining edge 2a contacts the inner wall surface of the tube body 2.

[0043] The outer end of the sealing sleeve 3 is in surface contact with the locking nut 4 , and the inner end of the sealing sleeve 3 has an inclined contact surface 3 a , and the contact surface 3 a is in contact with the outer side surface of the tube body 1 .

[0044] Such a structure enables the sealing sleeve 3 to stably seal the connection between the cannula 2 and the tube body 1 .

[0045] The sealing sleeve 3 is made of a flexible material. In this embodiment, the sealing sleeve 3 is made of a rubber material.

[0046] The interface structure is fixedly connected to a pipe 5 having external threads at the lower end of the pipe body 1 , and the pipe 5 is communicated with the inner cavity of the pipe body 1 .

[0047] The entire cleaning mechanism can be stably connected to the air pump via the connecting pipe 5 .

[0048] The inner diameter of the opening at the upper end of the tube body 1 is smaller than the inner diameter of the tube body 1 .

[0049] The opening at the upper end of the tube body 1 is in a convergent shape, which increases the pressure of the airflow passing therethrough, and is helpful for the spraying of the cleaning liquid and the rapid evaporation of the residual liquid.

[0050] Since the probe of the novel test tube type cleaning container will gradually translate relative to the tube body after being embedded in the cleaning mechanism, the cleaning liquid introduced from the liquid inlet can stably clean various parts of the probe. Since there are several liquid inlets, the cleaning stability of the probe can be further improved.

[0051] Of course, the cleaning liquid input from the liquid inlet will eventually be discharged from the liquid outlet stably and smoothly.

[0052] At the same time, a plurality of liquid inlets are evenly distributed on the outside of the tube body, and the structure of the entire cleaning mechanism is relatively compact, and has high practical value.

[0053] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments are within the scope of protection claimed by the present invention.
