DETAILED DESCRIPTION

[0021] 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.

[0022] See also Figure 1-Figure 7 A temporary storage device for intraoperative specimens at low temperature, comprising a housing 1; a storage liner 4 for storing intraoperative specimens; an outer cover 2 for sealing the storage liner 4; a self-opening device 9 for automatically opening the outer cover 2 and opening the closed position of the storage liner 4; the storage liner 4 is slidably connected to the housing 1, a seven-shaped groove 8 is provided on the storage liner 4, a key 7 is slidably connected to the seven-shaped groove 8, the key 7 is fixed inside the housing 1, and two handles 3 are rotatably connected to the housing 1. When the operator opens the handle 3, he can carry the entire storage device for transportation, which is very convenient and easy to use.

[0023] In this embodiment, a low-temperature interlayer 5 is provided between the storage liner 4 and the outer shell 1, an electrode patch 6 is installed on the storage liner 4, and a battery is provided at the bottom of the storage liner 4, and the battery is electrically connected to the electrode patch 6. Through the electrical connection between the battery and the electrode patch 6, a lower temperature can be generated in the low-temperature interlayer 5, and then the low temperature is conducted to the storage liner 4, so as to realize the low-temperature storage of the internal specimens, thereby facilitating the temporary storage of the specimens during the operation and avoiding the deterioration of the specimens. The electrode patch 6 belongs to the prior art and is also known as a cooling electrode sheet. The cooling electrode sheet is an electrothermal cooling element, which is composed of many thermoelectric complexes that are aggregated layer by layer but relatively independent. These thermoelectric complexes contain two different materials, namely P-type semiconductors and N-type semiconductors, and are therefore often referred to as thermoelectric pairs. The cooling electrode sheet can absorb heat from an object or space through the thermoelectric effect of the PN junction and release it to another place, thereby achieving a cooling effect. The working principle of the cooling electrode sheet is based on the thermoelectric effect. When one end is heated, a potential difference is formed due to the thermoelectric effect between the P-type semiconductor and the N-type semiconductor. This potential difference forms a thermal current in the cooling electrode sheet, which absorbs heat from this end and transfers it to the other end through the thermal conductor, and then releases it to the environment.

[0024] Furthermore, the storage liner 4 includes an upper liner 41 and a lower liner 42, the upper liner 41 is fixedly connected to the lower liner 42 through a U-shaped connecting tube 43, two seven-shaped grooves 8 are provided, and the two seven-shaped grooves 8 are both opened on the surface of the lower liner 42, and the lower liner 42 is slidably connected to the shell 1. The self-opening device 9 includes a flat plate 908, which is slidably connected to the gap between the upper liner 41 and the lower liner 42, and the bottom of the flat plate 908 is fixedly connected to a rack 901, and the bottom of the rack 901 is meshed with a central gear 905, and the central gear 905 is rotatably connected to a positioning frame 903, one end of the positioning frame 903 is fixed on the lower liner 42, and the central gear 905 is also meshed with a movable tooth plate 902, and the movable tooth plate 902 is connected to the inner wall of the shell 1. By rotating the shell 1 at a certain angle, the control key 7 is controlled to rotate to the vertical groove of the seven-shaped groove 8, and then the entire shell 1 will slide downward with gravity, and then the four movable tooth plates 902 connected to the shell 1 will be driven to move downward, and the movable tooth plates 902 will be engaged with the center gear 905 all the time, and then the center gear 905 will be rotated by the engagement between the teeth, and after the rotation, it will synchronously drive the rack 901 to slide obliquely, and the rack 901 will drive the flat plate 908 to slide obliquely, so the overall storage device can be opened automatically by sinking, and the operator only needs to control the shell 1 to rotate at a small angle, and then use gravity to slide down, and then open the space of the storage liner 4 as a whole, so that the operator can use the storage device conveniently without performing unnecessary operations, and the storage can be opened directly by using the relationship between sliding gravity.

[0025] Furthermore, the positioning frame 903 is fixedly connected to the limiting frame 904, the bottom of the limiting frame 904 is fixedly connected to the sliding shaft, the movable tooth plate 902 is provided with a sliding groove 906, the sliding groove 906 is slidably connected to the sliding shaft, and the inner wall of the shell 1 is provided with a movable groove 907, and the movable tooth plate 902 is slidably connected to the movable groove 907. During the rotation of the shell 1, the movable tooth plate 902 will slide at the position of the movable groove 907, so its relative X-axis direction will not change, and it will only move up and down in the Z-axis direction, and the structure that limits the movable groove 907 is the limiting frame 904, which limits the movable tooth plate 902 from rotating synchronously with the rotation of the shell 1, because the storage liner 4 is in contact with the bearing surface at this time, and it can be understood that the storage liner 4 is in a fixed state, so the storage liner 4 is fixed, and the plane direction of the movable tooth plate 902 will not move through the setting of the positioning frame 903.

[0026] In addition, there are four flat plates 908, and a soft film is provided between each adjacent flat plate 908, and the four flat plates 908 are distributed in a circular array with the center of the shell 1. The rack 901 and the movable tooth plate 902 are both meshed on the central gear 905, and the rack 901 and the movable tooth plate 902 are staggered. The purpose of the staggered distribution is to avoid the motion interference between the rack 901 and the movable tooth plate 902 when sliding, and after the staggered distribution, the two will be relatively staggered. The four flat plates 908 are conically closed when closed, and open in a conical shape after opening. After the four flat plates 908 are closed, a certain degree of sealing can be achieved through the soft film between the adjacent ones to avoid leakage of samples during transportation. The conical structure can also provide a certain guiding effect. After the specimen is placed, a funnel-shaped structure is used for guidance.

[0027] In addition, the outer cover 2 includes two outer cover plates 909, a connecting piece 912 is connected to the upper liner 41, a flip gear 913 is rotatably connected to the connecting piece 912, a slide plate 911 is fixedly connected to the flip gear 913, and the slide plate 911 is slidably connected in the outer cover plate 909 through a T-slot, and four movable tooth plates 902 are provided, and coarse teeth are provided on the two opposite movable tooth plates 902, and the coarse teeth are meshed with the flip gear 913. The outer cover 2 is opened by the other two movable tooth plates 902, and the outer cover 2 is divided into two outer cover plates 909. When the two movable tooth plates 902 slide down, the coarse teeth will mesh with the flip gear 913, which will drive the rotation of the flip gear 913, and then drive the rotation of the slide plate 911, and the slide plate 911 will drive the two outer cover plates 909 to open and flip relatively, and the main purpose of the outer cover 2 is to seal the storage liner 4 to prevent bacteria from entering from the outside during transportation. The inverted structure is set to divide the outer cover plate 909 into two surfaces, the bottom surface is surface A, and the top surface is surface B. When the sample is collected, surface A faces outward and surface B faces inward. After the collection is completed, the nurse wipes surface A because of potential contamination. When the outer cover plate 909 is flipped over, surface A faces inward and surface B faces outward, and surface B is a clean surface.

[0028] It is worth noting that one end of the slide plate 911 is connected to a telescopic spring 910, and one end of the telescopic spring 910 is connected to the inside of the outer cover plate 909. The bottom of the outer cover plate 909 is provided with a sealing rubber sleeve 914, and a rubber groove that cooperates with the sealing rubber sleeve 914 is provided on the upper liner 41. The telescopic spring 910 can provide a certain extrusion elastic force during the merging and sealing process of the two outer cover plates 909, so that the two outer cover plates 909 are squeezed and contacted together, and the sealing rubber sleeve 914 is abutted and contacted to ensure the sealing connection between the sealing rubber sleeve 914 and the upper liner 41. At the same time, the rubber groove provided on the upper liner 41 is to cooperate with the insertion of the sealing rubber sleeve 914, so as to isolate and seal the external impurities and air, and prevent the external air from contaminating or infecting the specimens stored in the inner liner 4. At the same time, the setting of the telescopic spring 910 also provides a buffer sliding space. Because the two outer cover plates 909 need to be opened or closed, if their positions are fixed, they will be stuck in the intersection position and will not be able to achieve a plane closure. The triangular structure is abutted. The telescopic spring 910 is set, so that the two outer cover plates 909 can be smoothly and horizontally merged in the open and merged states to achieve overall closure.

[0029] Working principle: first, when the entire storage device is closed and placed, the height of the outer shell 1 is higher than the height of the storage liner 4, and the load is also supported by the lower liner 42 in contact with the load-bearing surface. When the storage device needs to be opened later, it is only necessary to rotate the outer shell 1 at a certain angle to control the key 7 to rotate to the vertical groove of the seven-shaped groove 8. Then, the entire outer shell 1 will slide down following gravity, and then it will drive the four movable tooth plates 902 connected to the outer shell 1 to move downward. During the rotation of the outer shell 1, the movable tooth plate 902 will slide at the position of the movable groove 907, so its relative X-axis direction will not change, and only the Z-axis direction will move up and down, so the movable tooth plate 902 will always be engaged with the center gear 905, and then the center gear 905 will be rotated by the engagement between the teeth, and after rotation, it will synchronously drive the rack 901 to slide obliquely, and the rack 901 will drive the flat plate 908 to slide obliquely. The four plates 908 will slide synchronously, so the entire plate 908 will slide open in a conical manner, and during the operation, the specimen removed from the patient can be temporarily stored in the storage liner 4 through the expanded conical channel. The set limit frame 904 is used to limit the movable tooth plate 902 from rotating synchronously with the rotation of the housing 1, because the storage liner 4 is in contact with the bearing surface at this time. It can be understood that the storage liner 4 is in a fixed state, so the storage liner 4 is fixed and the plane direction of the movable tooth plate 902 will not move through the setting of the positioning frame 903. When the entire flat plate 908 is opened, the outer cover 2 will be opened through the other two movable tooth plates 902. The outer cover 2 is divided into two outer cover plates 909. When the two movable tooth plates 902 slide down, the coarse teeth will mesh with the flip gear 913, which will drive the rotation of the flip gear 913, and then drive the rotation of the slide plate 911, and the slide plate 911 will drive the two outer cover plates 909 to open and flip relatively. The main purpose of the outer cover 2 is to seal the storage liner 4 to prevent the entry of pathogens from the outside during the transportation process. When the specimen storage is completed, the lifting and rotation of the shell 1 can be directly controlled at this time, and then the whole is reset, and the key 7 is used to slide into the horizontal groove of the seven-shaped groove 8. At this time, the shell 1 will be stuck in a horizontal height position and will not slide down. When the operator opens the handle 3, he can carry the entire storage device for transportation, which is very convenient and easy to use.
