Description

Technical Field

[0001] The utility model relates to the technical field of cell slide making, in particular to a liquid needle module suitable for a liquid-based thin-layer cell slide making and staining machine. Background Art

[0002] The liquid-based thin-layer cell slide preparation and staining machine is an instrument that uses the principle of liquid-based cytology to achieve full automation from sample pre-treatment to slide preparation and staining. The liquid needle module is a collection device used for liquid-based cytology slide preparation, which can separate cell samples from liquid and transfer them to glass slides.

[0003] The existing liquid needle module needs to be composed of 5 components (such as elastic jacket 001, waste liquid needle 002, liquid needle 003, integrated fixing part 004, locking screw 005). Figure 1 However, this structure has many disadvantages:

[0004] 1. The processing technology is required to be high, and multiple components need to cooperate with each other. If the size is not in place, it is easy to have too large a clearance between the components, which eventually leads to the inability to lock the liquid needle;

[0005] 2. The processing materials are large and the processing steps are complicated, so the cost is relatively high. Utility Model Content

[0006] In view of the problems existing in the prior art, the utility model provides a liquid needle module suitable for a liquid-based thin layer cell slide staining machine, comprising:

[0007] An integrated fixing part, wherein a plurality of pinholes are formed through the integrated fixing part, and a waste liquid needle and a plurality of liquid needles are placed in each of the pinholes;

[0008] A plurality of locking screws are arranged on the side surface of the integrated fixing member, and a plurality of nuts are correspondingly arranged on the other side of the integrated fixing member, which are respectively connected with the threads of the locking screws.

[0009] Preferably, a plurality of slots are formed on the top of the integrated fixing member and pass through the pinholes.

[0010] Preferably, the outer diameters of the waste liquid needle line and each of the liquid needles are larger than the aperture of each of the needle holes.

[0011] Preferably, the integrated fixing piece is made of zinc alloy material.

[0012] Preferably, the integrated fixing piece is formed by a die-casting process.

[0013] Preferably, the waste liquid needle is made of 316L stainless steel.

[0014] Preferably, the inner and outer surfaces of the waste liquid needle are processed by a five-level metal polishing process.

[0015] Preferably, the side surface of the integrated fixing piece is also provided with a fixing screw hole, which is installed in cooperation with a fixing screw to be fixedly connected with an external device.

[0016] The above technical solution has the following advantages or beneficial effects: the use of an integrated fixing does not require the assembly of multiple parts like traditional liquid fixings, avoiding the problem of inappropriate dimensions between parts, excessive matching gaps and ultimately the inability to lock the liquid needle. In addition, the integrated fixing requires less processing material and simple processing steps, and is relatively low in cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 This is a structural schematic diagram of a traditional liquid needle module in a preferred embodiment of the present utility model;

[0018] Figure 2 In a preferred embodiment of the utility model, a liquid needle module is suitable for a liquid-based thin layer cell slide staining machine. DETAILED DESCRIPTION

[0019] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. The present invention is not limited to the implementation mode, and other implementation modes may also fall within the scope of the present invention as long as they meet the purpose of the present invention.

[0020] In a preferred embodiment of the present utility model, based on the above problems existing in the prior art, a liquid needle module suitable for a liquid-based thin layer cell slide staining machine is provided. Figure 2 As shown, including:

[0021] An integrated fixing member 1, wherein a plurality of needle holes 2 are formed therethrough, and a waste liquid needle 3 and a plurality of liquid needles 4 are placed in each of the needle holes 2;

[0022] A plurality of locking screws 5 are arranged on a side surface of the integrated fixing member 1 , and a plurality of nuts are correspondingly arranged on the other side of the integrated fixing member 1 , which are respectively connected with the locking screws 5 .

[0023] In a preferred embodiment of the present invention, a plurality of slots 6 are formed on the top of the integrated top fixing member 1 and pass through the pinholes 2 .

[0024] In a preferred embodiment of the present invention, the outer diameters of the waste liquid needle 3 and each liquid needle 4 are larger than the aperture of each needle hole 2 .

[0025] Specifically, in the present embodiment, in order to achieve a better locking effect and prevent the liquid needle 4 from loosening, the outer diameters of the waste liquid needle 3 and the liquid needle 4 are made slightly larger than the aperture of the needle hole 2, so as to achieve an interference fit between the waste liquid needle 3 and the liquid needle 4 and the needle hole 2; further, since the outer diameters of the waste liquid needle 3 and the liquid needle 4 are made slightly larger than the aperture of the needle hole 2, the integrated fixing part 1 will be deformed when the waste liquid needle 3 and the liquid needle 4 are inserted into the needle hole 2, and the integrated fixing part 1 will be squeezed and deformed when tightened by the locking screw 5 and the nut, so a slot 6 that passes through each needle hole 2 is also opened at the top of the integrated fixing part 1, reserving a certain deformation margin to avoid large deformation such as outward protrusion or inward depression when the integrated fixing part 1 is deformed.

[0026] In a preferred embodiment of the present invention, the waste liquid needle 3 is made of 316L stainless steel.

[0027] In a preferred embodiment of the present invention, the inner and outer surfaces of the waste liquid needle 3 are processed by a five-level metal polishing process.

[0028] In a preferred embodiment of the present invention, the integrated fixing member 1 is made of zinc alloy material.

[0029] In a preferred embodiment of the present invention, the integrated fixing member 1 is formed into an integrated structure by a die-casting process.

[0030] Specifically, in the present embodiment, the die-casting process is adopted to form an integrated fixing part 1, which does not need to be assembled with multiple parts like the traditional liquid fixing parts, thus avoiding the problem that the dimensions between the parts are not in place, the fitting gap is too large and the liquid needle cannot be locked. In addition, the die-casting process requires less processing materials, has simple processing steps and is relatively low in cost.

[0031] In addition, the waste liquid needle 3 is made of 316L stainless steel with higher corrosion resistance, and the inner and outer surfaces of the waste liquid needle 3 are subjected to a metal polishing process [polishing level 5 (i.e., mirror polishing)], thereby reducing blockage caused by the reaction between the surface of the waste liquid needle 3 and the reagent, and reducing the impact on the staining effect.

[0032] In order to achieve the locking effect, the several holes 2 of the integrated fixing part 1 are interference fit with the liquid needle 4, and then the relative positions of the several liquid needles 4 are adjusted by the matching installation fixture, and finally the several locking screws 5 on the side are locked.

[0033] In a preferred embodiment of the present invention, a fixing screw hole 7 is further provided on the side of the integrated fixing member 1, which is installed in cooperation with a fixing screw to be fixedly connected with an external device.

[0034] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the contents of this specification and illustrations should be included in the protection scope of the present invention.
