Detailed Description
The invention will be further described with reference to the following specific embodiments and the accompanying drawings.
Referring to fig. 1 to 7, the present embodiment discloses a device for preserving perfusate for liver at low temperature, which comprises an outer layer heat insulation cylinder 1, an inner layer ice bag cooling cylinder 2 and a heat insulation cover 3, wherein the outer layer heat insulation cylinder 1 is a cylinder with an open top end,
the inner-layer ice bag cooling cylinder 2 is detachably arranged in the outer-layer heat insulation cylinder 1, the inner-layer ice bag cooling cylinder 2 is a cylindrical cylinder with an opening at the top end, a filling liquid bag placing cylinder 4 is integrally formed in the inner cavity of the inner-layer ice bag cooling cylinder 2, the filling liquid bag placing cylinder 4 is used for placing a filling liquid bag 5, a hanging ring 6 is arranged at the upper end of the filling liquid bag 5, a filling liquid pipe 7 is arranged at the lower end of the filling liquid bag 5, and the filling liquid pipe 7 sequentially penetrates through the bottoms of the inner-layer ice bag cooling cylinder 2 and the outer-layer heat insulation cylinder 1. A plurality of ice bag 8 placing areas are separated between the inner wall of the inner layer ice bag cooling cylinder 2 and the outer wall of the perfusate bag placing cylinder 4 through partition plates 12, and ice bags 8 used for refrigerating the perfusate bags 5 are placed in the ice bag 8 placing areas.
The lower bottom surface integrated into one piece of thermal-insulated lid 3 has a plurality of and ice bag 8 places the open-top assorted voussoir 9 in district, place the open-top in district through voussoir 9 embedding ice bag 8, can further form thermal-insulated heat preservation effect, the lower bottom surface center of thermal-insulated lid 3 is provided with the couple 10 that is used for hanging perfusate bag 5, because directly lie perfusate bag 5 in the perfusate bag places a section of thick bamboo 4, can arouse perfusate bag 5 fold, lead to partial perfusate to remain in perfusate bag 5 and can't draw forth completely, therefore, when using, hang the link 6 of the upper end of perfusate bag 5 on with couple 10, guarantee that perfusate bag 5 is perpendicular all the time, can make the perfusate in the perfusate bag 5 all draw forth, do not cause the perfusate to remain. The center of the upper end face of the heat insulation cover 3 is provided with a square installation cavity, and a hidden handle 11 is embedded in the installation cavity. The hidden handle 11 comprises a mounting seat 1101, the mounting seat 1101 is inlaid in a mounting cavity, an open slot 1102 is formed from the upper end face to the lower end face of the mounting seat 1101, and a handle 1103 with a semicircular ring structure is rotatably connected in the open slot 1102 through a pivot 1104. When the heat insulation cover 3 needs to be lifted, the handle 1103 is rotated to expose the semicircular arc surface of the handle 1103 out of the open slot 1102, and when the heat insulation cover 3 is buckled on the outer heat insulation cylinder 1, the handle 1103 is rotated to flush the horizontal plane of the handle 1103 with the upper end surface of the mounting seat 1101, so that the semicircular arc surface is hidden in the open slot 1102, and space is not occupied.
The inner sides of the outer layer heat insulation cylinder 1 and the heat insulation cover 3 are adhered with a layer of nano-base heat insulation soft felt so as to realize heat insulation and heat preservation in the cylinder, reduce the melting speed of the ice bag 8 and ensure the refrigeration effect of the perfusate.
As can be seen from the above, the device for storing the perfusate for the liver at a low temperature disclosed in this embodiment stores the perfusate for the liver at a high temperature in a bag in the cylinder, places an ice bag in the cylinder to implement low-temperature refrigeration of the perfusate, and uses a heat insulating material to delay the change of the temperature in the cylinder, thereby ensuring the refrigeration effect and greatly improving the quality of the liver.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
