Description

Technical Field

[0001] The invention relates to the technical field of detection sample storage, and in particular to a sample storage device for oncology detection. Background Art

[0002] The essence of tumor cells is the tumor. Tumor tissue is composed of two parts: the substance and the stroma. The substance of the tumor is the tumor cell, which is the main component of the tumor and has tissue-origin specificity. It determines the biological characteristics of the tumor and the particularity of each tumor. Usually, the tissue origin of various tumors is identified based on the substantial morphology of the tumor, and the tumor is classified, named and histologically diagnosed. The benign and malignant nature of the tumor and the degree of malignancy of the tumor are determined based on its degree of differentiation, maturity and the size of its heterogeneity. Tumor cells have three significant basic characteristics: immortality, migration and loss of contact inhibition. In addition, tumor cells have many physiological, biochemical and morphological characteristics that are different from normal cells.

[0003] When testing oncology samples, it is necessary to store the tumor samples to avoid the samples being infected by other substances during the storage process. The samples to be tested need to be sealed and kept away from light and quickly frozen. If the test samples need to be transported, the samples are likely to collide with the placement device, causing damage to the samples. Therefore, it is necessary to have a sample storage device for oncology testing that is highly practical and has the characteristics of being able to fix the test sample between the four clamps by rotating the guide extension surface when the pressure hook rod slides to the bottom on the ball and just snaps together with the pressure hook rod, thereby preventing the storage tank from being disturbed by the outside world and the test sample from colliding with the storage tank wall. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a sample storage device for oncology detection, comprising: A sealed storage tank, the sealed storage tank comprising a tank body, both sides of the top of the tank body are fixedly connected with anti-spray walls, the outer surface of the anti-spray walls is fixedly connected with a clamping block, and the outer surface of the clamping block is threadedly connected with a sealing cover; A storage platform, the storage platform comprises a carrying plate, a limiting groove is provided on the outer surface of the carrying plate, a limiting hook is fixedly connected to the surface of the carrying plate, and a mounting ring is fixedly connected to the top outer edge of the carrying plate; The clamping member includes a positioning seat, a sliding column is fixedly connected to the top of the positioning seat, a clamping arc rod is slidably connected to the outer surface of the sliding column, a pressing sheet is fixedly connected to the surface of the clamping arc rod, a pressure hook rod is fixedly connected to the surface of the pressing sheet, and the pressure hook rod is adapted to the limit hook member; A low-temperature storage tank, the low-temperature storage tank includes a storage bag, a guide wall is opened inside the storage bag, the outer surface of the storage bag is slidably connected to a connecting plate, the surface of the connecting plate is fixedly connected to a liquid outlet, and is in a trumpet shape with a larger upper part and a smaller lower part, the surface of the liquid outlet is fixedly connected to a mounting wall, and the surface of the mounting wall is rotatably connected to a turn-out piece.

[0005] The limit hook comprises a pressure-blocking base, the surface of which is rotatably connected with a supporting rib, the surface of which is provided with a guiding extension surface, and the surface of which is provided with a ball bearing. The medical staff twists the sealing cover to open it, and the clamping arc rod is located at the upper end of the sliding column. The medical staff places the test sample to a position above the extrusion sheet. Due to the pressure of the test sample, the clamping arc rod is forced to slide downward on the surface of the sliding column to the surface of the positioning seat, so that the pressure hook rod follows the clamping arc rod and slides downward to the position where the pressure hook rod is connected to the limit hook. A ball is arranged on the surface of the pressure-blocking base. When the pressure hook rod contacts the pressure-blocking base, the thrust of the pressure hook rod on the pressure-blocking base causes the ball to roll outward. Since a supporting rib is arranged under the ball, the supporting rib also rolls when the ball rolls. The rolling of the supporting rib will drive the guide extension surface to reverse upward. When the pressure hook rod slides to the lower end on the ball, the guide extension surface reverses one circle and just snaps together with the pressure hook rod, thereby fixing the test sample between the four clamping parts to prevent the storage tank from being disturbed by the outside world and causing the test sample to collide with the wall of the storage tank.

[0006] The rotating member comprises a rotating shaft, and rotating plates are distributed circumferentially on the outer surface of the rotating shaft. The rotating plates are arc-shaped, and the arc shape of the rotating plates matches the size and shape of the lower part of the liquid outlet.

[0007] A continuing rotation sleeve is sleeved on the surface of the rotating shaft, and the other end of the continuing rotation sleeve is fixedly connected to the surface of the limit stop ring. A plurality of inclined extrusion surfaces are distributed circumferentially inside the continuing rotation sleeve, and an extrusion spring is sleeved on the outer surface of the continuing rotation sleeve, and the two ends of the extrusion spring are respectively against the shell and the limit stop ring.

[0008] The outer surface of the extrusion spring is sleeved with a slot, which is clamped on the surface of the mounting wall. The surface of the slot is clamped with a guide block. The inner surface of the guide block is circumferentially distributed with extrusion blocks of the same number as the inclined extrusion surface, and the inclined extrusion surface is extrusion-fitted with the extrusion blocks. By pouring low-temperature liquid into the storage bag before placing the test sample, the impact generated when the liquid is poured in will push the low-temperature liquid to be discharged from the liquid outlet and accumulated in the tank body when the rotating part rotates. Since the liquid in the tank body is more than the liquid in the low-temperature storage tank, the pressure in the tank body increases, so that the medium in the tank body pushes the limit baffle ring, and the extrusion spring is squeezed. At this time, the extrusion block contacts and squeezes the continued rotation sleeve and the inclined extrusion surface on the continued rotation sleeve. Through the extrusion cooperation of the extrusion block and the inclined extrusion surface, the continued rotation sleeve is slowly squeezed and rotated, and the rotating shaft rotates synchronously with the continued rotation sleeve under the drive of the continued rotation sleeve, and the rotating piece on the rotating shaft also starts to rotate with the rotating shaft, thereby increasing the fluidity of the low-temperature liquid in the low-temperature storage tank, and achieving the effect of stirring the low-temperature liquid to avoid the temperature increase of the inner wall of the tank body due to the external influence when the outside temperature is too high in summer, avoiding long-term contact between the liquid and the inner wall of the tank body, and maintaining the temperature in the tank body.

[0009] A circumferential limit hole is provided on the surface of the continuing rotation sleeve, and the circumferential limit hole is an elongated through hole. One end of the rotating shaft inserted in the elongated through hole matches the size and shape of the elongated through hole. A return spring is provided on the surface of the rotating shaft, and the two ends of the return spring are respectively against the mounting wall and the continuing rotation sleeve.

[0010] The bottom end of the liquid outlet is fixedly connected with a bottom wall, and a clamping groove is provided on the surface of the bottom wall.

[0011] The surface of the limiting groove is slidably connected with a telescopic rod, the bottom end of the telescopic rod is fixedly connected with an anti-slip ring, adjacent surfaces of the anti-slip ring are fixedly connected with a connecting ring, the side of the anti-slip ring close to the low-temperature storage tank is fixedly connected to the surface of the connecting plate, the lower surface of the connecting plate is fixedly connected with a pressing block, and the pressing block is adapted to the positioning groove. When the test sample is fixed, the supporting plate is subjected to pressure to squeeze the telescopic rod at the bottom of the mounting ring downward, so that the pressing block slides on the surface of the low-temperature storage tank and is connected to the bottom wall to increase the stability of the low-temperature storage tank.

[0012] The present invention provides a sample storage device for oncology detection. It has the following beneficial effects:

[0013] 1. The sample storage device for oncology detection is opened by medical staff by twisting the sealing cover, and the clamping arc rod is located at the upper end of the sliding column. The medical staff places the detection sample to the position above the extrusion plate. Due to the pressure of the detection sample, the clamping arc rod is subjected to force to slide downward on the surface of the sliding column to the surface of the positioning seat, so that the pressure hook rod follows the clamping arc rod and slides downward at the same time to the position where the pressure hook rod and the limiting hook are connected. Since the surface of the pressure blocking matrix is ​​provided with a ball, when the pressure hook rod contacts the pressure blocking matrix, the thrust of the pressure hook rod on the pressure blocking matrix causes the ball to roll outward. Since support ribs are provided under the ball, the support ribs also roll when the ball rolls, and the rolling of the support ribs will drive the guide extension surface to reverse upward. When the pressure hook rod slides to the lower end on the ball, the guide extension surface reverses one circle and just snaps together with the pressure hook rod, thereby fixing the detection sample between the four clamping parts to prevent the storage tank from being disturbed by the outside and causing the detection sample to collide with the storage tank wall.

[0014] 2. The sample storage device for oncology testing, when the test sample is taken out, the squeeze sheet loses pressure and bounces upward, so that the pressure hook rod is lifted upward, and drives the guide extension surface and the support rib to rotate back to the starting position, so that the pressure hook rod and the guide extension surface are reset.

[0015] 3. The sample storage device for oncology detection increases the stability of the low-temperature storage tank by applying pressure to the support plate when the detection sample is fixed, so that the telescopic rod at the bottom of the mounting ring is squeezed downward, so that the pressing block slides on the surface of the low-temperature storage tank and is connected to the bottom wall.

[0016] 4. The sample storage device for oncology detection pours low-temperature liquid into the storage bag before placing the detection sample. The impact generated when the liquid is poured will push the low-temperature liquid to be discharged from the liquid outlet and accumulated in the tank body when the rotating part rotates. Since the liquid in the tank body is more than the liquid in the low-temperature storage tank, the pressure in the tank body increases, so that the medium in the tank body pushes the limit baffle ring, and the extrusion spring is squeezed. At this time, the extrusion block contacts and squeezes the continuous rotation sleeve and the inclined extrusion surface on the continuous rotation sleeve. Through the extrusion cooperation of the extrusion block and the inclined extrusion surface, the continuous rotation sleeve is slowly squeezed and rotated, and the rotating shaft rotates synchronously with the continuous rotation sleeve under the drive of the continuous rotation sleeve, and the rotating piece on the rotating shaft also starts to rotate with the rotating shaft, thereby increasing the fluidity of the low-temperature liquid in the low-temperature storage tank, so as to achieve the effect of stirring the low-temperature liquid to avoid the temperature increase of the inner wall of the tank body due to the external influence when the external temperature is too high in summer, avoid long-term contact between the liquid and the inner wall of the tank body, and maintain the temperature in the tank body.

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0020] Example 1 like Figure 1 - Figure 6As shown, the present invention provides a technical solution: a sample storage device for oncology detection, comprising a storage sealed tank 1, the storage sealed tank 1 comprises a tank body 12, both sides of the top of the tank body 12 are fixedly connected with anti-spray walls 14, the outer surface of the anti-spray wall 14 is fixedly connected with a clamping block 13, and the outer surface of the clamping block 13 is threadedly connected with a sealing cover 11; The storage platform 5 includes a carrying plate 53. The outer surface of the carrying plate 53 is provided with a limiting groove 54. The surface of the carrying plate 53 is fixedly connected to a limiting hook 52. The top outer edge of the carrying plate 53 is fixedly connected to a mounting ring 51. The clamping member 4 includes a positioning seat 43, a sliding column 41 is fixedly connected to the top of the positioning seat 43, a clamping arc rod 42 is slidably connected to the outer surface of the sliding column 41, a pressing sheet 44 is fixedly connected to the surface of the clamping arc rod 42, a pressure hook rod 45 is fixedly connected to the surface of the pressing sheet 44, and the pressure hook rod 45 is adapted to the limiting hook 52; The limiting hook 52 includes a pressure-blocking base 523 , a surface of which is rotatably connected to a support rib 522 , a surface of which is provided with a guide extension surface 521 , and a surface of which is provided with a ball bearing 524 .

[0021] The bottom end of the liquid outlet 83 is fixedly connected to a bottom wall 9, and a clamping groove 10 is provided on the surface of the bottom wall 9; The surface of the limiting groove 54 is slidably connected with the telescopic rod 6, the bottom end of the telescopic rod 6 is fixedly connected with the anti-slip ring 3, the adjacent surfaces of the anti-slip ring 3 are fixedly connected with the connecting ring 7, the side of the anti-slip ring 3 close to the low-temperature storage tank 8 is fixedly connected to the surface of the connecting plate 84, the lower surface of the connecting plate 84 is fixedly connected with the pressing block 2, and the pressing block 2 is adapted to the positioning groove 10.

[0022] When in use, the medical staff twists the sealing cover 11 to open it, and the clamping arc rod 42 is located at the upper end of the sliding column 41. The medical staff places the test sample to the position above the extrusion sheet 44. Due to the pressure of the test sample, the clamping arc rod 42 is forced to slide downward on the surface of the sliding column 41 to the surface of the positioning seat 43, so that the pressure hook rod 45 follows the clamping arc rod 42 and slides downward at the same time to the position where the pressure hook rod 45 and the limiting hook 52 are connected. Since the surface of the pressure blocking base 523 is provided with a ball 524, when the pressure hook rod 45 contacts the pressure blocking base 523, the pressure hook rod 45 is pressed against the pressure blocking base 523. The thrust on the pressure-blocking base 523 causes the ball 524 to roll outward. Since a support rib 522 is provided below the ball 524, the support rib 522 also rolls when the ball 524 rolls. The rolling of the support rib 522 drives the guide extension surface 521 to reverse upward. When the pressure hook rod 45 slides to the lowest end on the ball 524, the guide extension surface 521 reverses one circle and just snaps together with the pressure hook rod 45, thereby fixing the test sample between the four clamping members 4, preventing the storage tank from being disturbed by the outside and causing the test sample to collide with the storage tank wall. When the test sample is taken out, the squeezing sheet 44 loses pressure and bounces upward, so that the pressure hook rod 45 is lifted upward, and drives the guide extension surface 521 and the support rib 522 to rotate back to the starting position, so that the pressure hook rod 45 and the guide extension surface 521 are reset; When the test sample is fixed, the support plate 53 is subjected to pressure to squeeze the telescopic rod 6 at the bottom of the mounting ring 51 downward, so that the pressing block 2 slides on the surface of the low-temperature storage tank 8 and is clamped into the bottom wall 9 to increase the stability of the low-temperature storage tank 8.

[0023] Example 2 like Figure 7 - Fig. 9 As shown, the low-temperature storage tank 8 comprises a storage capsule 81, a guide wall 82 is provided inside the storage capsule 81, a connecting plate 84 is slidably connected to the outer surface of the storage capsule 81, a liquid outlet 83 is fixedly connected to the surface of the connecting plate 84, and is in a trumpet shape with a larger upper part and a smaller lower part, a mounting wall 85 is fixedly connected to the surface of the liquid outlet 83, and a turn-out member 86 is rotatably connected to the surface of the mounting wall 85; The rotating member 86 includes a rotating shaft 866, and the outer surface of the rotating shaft 866 is circumferentially distributed with rotating pieces 867, and the rotating pieces 867 are arc-shaped, and the arc shape of the rotating pieces 867 is matched with the size and shape of the lower part of the liquid outlet 83; The surface of the rotating shaft 866 is sleeved with a continuous rotation sleeve 865, and the other end of the continuous rotation sleeve 865 is fixedly connected to the surface of the limit stop ring 862. A plurality of inclined extrusion surfaces 8652 are distributed in a circumference in the continuous rotation sleeve 865. The outer surface of the continuous rotation sleeve 865 is sleeved with an extrusion spring 868, and the two ends of the extrusion spring 868 are respectively against the housing 8651 and the limit stop ring 862; The outer surface of the extrusion spring 868 is sleeved with a slot 861, which is clamped on the surface of the mounting wall 85. The surface of the slot 861 is clamped with a guide block 864. The inner surface of the guide block 864 is circumferentially distributed with extrusion blocks 863 of the same number as the inclined extrusion surface 8652. The inclined extrusion surface 8652 is extruded and adapted with the extrusion blocks 863. A circumferential limiting hole 8654 is provided on the surface of the rotating sleeve 865. The circumferential limiting hole 8654 is a long strip through hole. One end of the rotating shaft 866 inserted into the long strip through hole matches the size and shape of the long strip through hole. The return spring 8653 is sleeved on the surface of the rotating shaft 866, and the two ends of the return spring 8653 are respectively against the mounting wall 85 and the rotating sleeve 865. When in use, before placing the test sample, cryogenic liquid is poured into the storage bag 81. The impact generated when the liquid is poured in will push the turn-out member 86 to rotate, and the cryogenic liquid is discharged from the liquid outlet 83 and accumulated in the tank body 12. Since the liquid in the tank body 12 is more than the liquid in the cryogenic storage tank 8, the pressure in the tank body 12 increases, so that the medium in the tank body 12 pushes the limit stop ring 862, and the extrusion spring 868 is squeezed. At this time, the extrusion block 863 contacts and squeezes the rotating sleeve 865 and the inclined extrusion surface 8652 on the rotating sleeve 865. The pressing block 863 cooperates with the extrusion of the inclined extrusion surface 8652, and the rotating sleeve 865 is slowly squeezed to rotate, and the rotating shaft 866 rotates synchronously with the rotating sleeve 865 under the drive of the rotating sleeve 865, and the rotating piece 867 on the rotating shaft 866 also starts to rotate with the rotating shaft 866, thereby increasing the fluidity of the low-temperature liquid in the low-temperature storage tank 8, achieving the effect of stirring the low-temperature liquid to avoid the temperature of the inner wall of the tank body 12 being affected by the outside world when the outside temperature is too high in summer, avoiding long-term contact between the liquid and the inner wall of the tank body 12, and maintaining the temperature inside the tank body 12.
