Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to an automatic tissue section mounting device. Background Art

[0002] Mounting is to seal and preserve tissue sections between a glass slide and a coverslip, dropping a small amount of mounting adhesive so that it does not come into contact with air, preventing oxidation and fading, which is beneficial for microscopic examination and preservation. Neutral balsam is usually used as the mounting adhesive; however, at present, mounting is mainly carried out manually. During the actual mounting process, there is a problem of uneven dropping of the adhesive, which is likely to cause excessive overflow of the mounting adhesive, generating an odor and having a certain toxicity. If the amount of the mounting adhesive is too small, the tissue on the tissue section is not completely covered or air bubbles are easily generated. In addition, after dropping a small amount of mounting adhesive on the tissue section, a coverslip needs to be placed on the tissue section with the dropped mounting adhesive. At present, during the actual mounting process, an operator needs to pick up the coverslip and place it on the tissue section. Since the coverslip is thin and has a sharp edge, it is not easy to pick up and is likely to scratch the operator during the picking process, presenting a safety hazard. Therefore, there is an urgent need for a mounting device that can automatically drop a quantitative amount of mounting adhesive and automatically place the coverslip on the tissue section. Summary of the Invention

[0003] An object of the present invention is to overcome at least one of the above-mentioned deficiencies of the prior art, and to provide an automatic tissue section mounting device that can automatically drop a quantitative amount of mounting adhesive and automatically place the coverslip on the tissue section.

[0004] The technical solution for the present invention to solve the above technical problems is as follows: An automatic tissue section mounting device, comprising:

[0005] A support frame, on which a glass slide placement plate for placing a glass slide with a tissue section is provided;

[0006] An automatic mounting adhesive dropping device for dropping a quantitative amount of mounting adhesive on the tissue section placed on the glass slide. A plurality of the automatic mounting adhesive dropping devices are provided, and the plurality of automatic mounting adhesive dropping devices are installed at intervals on the support frame and above the glass slide placement plate;

[0007] An automatic coverslip placing device for covering a coverslip on the tissue section placed on the glass slide after dropping a quantitative amount of mounting adhesive. A plurality of the automatic coverslip placing devices are provided, and the plurality of automatic coverslip placing devices are installed at intervals on the support frame and above the glass slide placement plate;

[0008] A microprocessor, and the automatic mounting adhesive dropping device and the automatic coverslip placing device are respectively electrically connected to the microprocessor.

[0009] The beneficial effects of the present invention are as follows: In the present invention, a plurality of automatic cover slip glue dropping devices for dropping a quantitative amount of cover slip glue on tissue sections placed on a glass slide are provided on the support frame. The automatic cover slip glue dropping devices are electrically connected to the microprocessor, which facilitates dropping a quantitative amount of cover slip glue on multiple tissue sections, helps reduce the influence of human factors on the dropped cover slip glue, is conducive to accurately dropping a certain amount of cover slip glue, avoids excessive or insufficient cover slip glue being dropped, and is beneficial to improving the quality of cover slipping. In addition, a plurality of automatic cover slip placing devices for placing a cover slip on a tissue section placed on a glass slide after dropping a quantitative amount of cover slip glue are provided. The automatic cover slip placing devices are electrically connected to the microprocessor. By using the automatic cover slip placing devices to place the cover slip on the cover slip glue on the tissue section, it helps avoid the safety hazard of the operator being scratched when picking up the cover slip. Thus, the automatic tissue section cover slipping device in the present invention can automatically drop a quantitative amount of cover slip glue and can automatically place the cover slip on the tissue section, avoiding excessive or insufficient cover slip glue being dropped, and improving the quality and efficiency of cover slipping.

[0012] According to an embodiment of the present invention, the automatic cover slip glue dropping device includes:

[0013] A housing, in which a cover slip glue storage cavity for storing cover slip glue is provided;

[0017] A second one-way valve is connected to the sealant delivery pipe and is located between the output end and the connection between the sealant suction and discharge device and the sealant delivery pipe. The one-way conduction direction of the second one-way valve is from the connection between the sealant suction and discharge device and the sealant delivery pipe to the output end; the first one-way valve and the second one-way valve are alternately conducted and closed under the action of the sealant suction and discharge device, and a quantitative amount of sealant is output from the output end of the sealant delivery pipe after completing an alternating process of conduction and closing.

[0018] In this embodiment, a sealant storage cavity for storing sealant is provided in the housing, which is convenient for storing sealant in the housing. A first one-way valve and a second one-way valve are also connected to the sealant delivery pipe, and a sealant suction and discharge device is connected between the first one-way valve and the second one-way valve.

The first one-way valve and the second one-way valve are alternately conducted and closed under the action of the sealant suction and discharge device, and a quantitative amount of sealant is output from the output end of the sealant delivery pipe after completing an alternating process of conduction and closing. Thus, by driving the driving mechanism once or several times, an appropriate amount of sealant can be output and dropped on the tissue section for dropping glue on the tissue section, so as to facilitate placing a cover glass on the tissue section for sealing. Therefore, the amount of sealant dropped on the tissue section is appropriate and the added amount can be controlled, avoiding too much or too little sealant being dropped, which is beneficial to improving the quality of sealing. At the same time, the consistency of sealing the tissue section is improved.

The piston 232 is fitted and installed in the sealing sheet glue suction and discharge cavity 233. One end of the push-pull rod 237 is connected to the piston 232, and the other end passes through the housing. The push-pull rod 237 is pushed and pulled by the electric push rod to drive the piston 232 to move. When the electric push rod pulls the push-pull rod 237 out of the housing, the piston 232 moves outwards by a certain displacement, and the sealing sheet glue between the first one-way valve 223 and the second one-way valve 225 is adsorbed, while the second one-way valve 225 closes and the first one-way valve 223 opens, and a certain amount of sealing sheet glue enters the sealing sheet glue output pipe between the first one-way valve 223 and the second one-way valve 225; when the electric push rod pushes the push rod 312 into the housing, the piston 232 moves forward to return to its original position, and the sealing sheet glue between the first one-way valve 223 and the second one-way valve 225 is squeezed, while the first one-way valve 223 closes and the second one-way valve 225 opens, and a certain amount of sealing sheet glue is output from the output end of the sealing sheet glue output pipe; thus, by pushing and pulling the push rod 312 by the electric push rod, the amount of the sealing sheet glue dropped on the tissue section is appropriate and the added amount can be controlled, avoiding too much or too little of the dropped sealing sheet glue. The electric push rod in this embodiment is the first electric push rod 8, and the telescopic rod on the first electric push rod 8 is coaxially arranged with the push rod 312.

The first spring 236 undergoes elastic deformation under the pressure, the piston 232 moves forward and extrudes the sealing film adhesive. When the push-pull rod 237 is released, the first spring 236 restores its elasticity, the push rod 312 resets, the piston 232 resets and sucks a certain amount of sealing film adhesive into the sealing film adhesive conveying pipe 22, facilitating the next operation of pushing the push rod 312, so that the piston 232 performs the next extrusion of the sealing film adhesive to output a certain amount of the sealing film adhesive.
