Technical Field
[0001] The invention relates to the technical field of medical auxiliary materials, and in particular to a protective bottle cover for preventing mannitol from crystallizing in winter. Background Art
[0002] Mannitol is commonly used in clinical practice to reduce intracranial pressure, reduce intraocular pressure, and promote renal excretion. Mannitol is prone to crystallization during use and storage, especially in low temperature environments or at high concentrations. Crystallization may affect drug infusion, product stability, and other aspects.
[0003] The commonly used method is to store it in a high-temperature box. In clinical use, there are two ways to protect mannitol from crystallization. The first is to heat the infusion tube, but the heating temperature of the plastic tube is difficult to control. The other is external heating. In the later stage of use, crystallization will occur again. Especially in the process of emergency treatment outside the hospital, there is no good way to prevent crystallization. Summary of the invention

The conduction strip and the arc-shaped plate are integrally formed to form the heat transfer plate 4.
[0039] The heat transfer plate 4 is filled with one or two of quicklime, magnesium powder, iron powder, salt and bentonite or diatomaceous earth.
[0040] The outside of the heating jacket 2 is provided with a honeycomb-shaped heat-insulating jacket, and the inner layer is a heat-insulating layer.
[0041] The bottle label part 6 includes a heat-insulating part 61, a heat-collecting sleeve 62 is arranged on the inner side of the heat-insulating part 61, a built-in metal plate 64 is arranged in the heat-collecting sleeve 62, and evenly distributed holes 65 are arranged on the built-in metal plate 64. The holes 65 are filled with paraffin 66. An insertion port 63 is arranged at the heat-collecting sleeve 62, and the insertion part 41 is inserted into the insertion port 63.
[0042] In fact, the pore chamber 65 and the paraffin 66 in the pore chamber 65 are arranged in the form of microcapsules, which occupy a small space, are light in weight after solidification, and are convenient for heat to be concentrated at various positions of the bottle body and heated evenly.
[0043] The heating sleeve 2 is provided with a hook rope 7, and the hook rope 7 is hung on the reverse hook 42. When used outdoors, it is only necessary to hang the hook rope 7 on the reverse hook 42.
[0044] The bottleneck binding part 3 includes two types of long specifications and segment specifications, and is mainly made of soft silicone or elastic textile material, and is used to wrap the neck of the mannitol bottle body. The main function is that the bottleneck binding part 3 can be manually opened, and the mannitol bottle body can be quickly replaced;
[0045] Regarding the heating sleeve 2, the honeycomb insulation sleeve is used to block the internal heat while making the conducted heat disappear quickly on the surface. When the medical staff holds the sleeve, the heat they feel is below the safe temperature. In the process of holding the sleeve, the medical staff may wear protective gloves, which have low friction. The honeycomb structure of the honeycomb insulation sleeve increases the safety during the holding process. Regarding the insulation layer, it can be a common insulation material, such as foam cotton.
[0046] Regarding the bottle sticker part 6, the bottle sticker part 6 is hung on the reverse hook 42 through the hook rope 7. During use, the heat source chamber 1 and the heating sleeve 2 remain separated, that is, a single one can be replaced, or a separate heating sleeve 2 can be used separately. At this time, it can be hung on the water hanging rack through the hook rope 7. The specific use is as follows:
[0047] Scenario 1: When used in a hospital, due to the perfect basic configuration of the hospital, the heating sleeve 2 can be directly placed on the heating device for ten minutes to ensure that the temperature is below 60 degrees Celsius. In this way, the internal built-in metal plate 64 obtains the temperature, so that the internal built-in metal plate 64 in the internal hole chamber 65 melts into a transparent liquid, and passive constant temperature is achieved through the fixed phase change point of paraffin such as 42°C. It is important to note that a low-melting point wax sheet with a melting point of 45°C is added between the paraffin layer and the outer layer. When the temperature is too high, the wax sheet melts and absorbs heat to prevent the drug solution from overheating, and then the mannitol bottle is put inside.
[0048] Scenario 2: When used in an emergency scenario, by configuring the heat source chamber 1, in the practical process, mannitol can be placed in the bottle sticker part 6 first, and then the hook rope 7 is hung on the reverse hook 42, and then the reaction filler 14 is placed on the heat-bearing plate 17 in the inner chamber 18. It should be noted that a hole is reserved in the center of the reaction filler 14 for the acupuncture head 15 to pass through. After the reaction filler 14 is placed, the reaction filler 14 is pressed by the pressing plate 16, and then the pressing plate 16 is rotated to fix it on the acupuncture head 15, and then the water bag 12 is attached to the fixing cover 11, and then fixed on the protective cover 13. When in use, the fixing cover 11 can be pressed so that after the water bag 12 is punctured, water enters the surface of the reaction filler 14 from the hole of the pressing plate 16. It should be noted that there are sieve holes on the pressing plate 16, so that after quicklime, magnesium powder, iron powder, and salt come into contact with water, CaO+H 2 O→Ca(OH) 2 + heat; Mg+2H 2 O→Mg(OH) 2 +H 2 + heat; Fe+H 2 O+O 2 →Fe 2 O 3 +H 2 + heat; it should be noted that calcium oxide is the main heat-generating substance, iron powder enhances the heat release of the reaction; carbon powder is sometimes used to stabilize the temperature; salt promotes the electrolytic reaction and improves the heat release efficiency; bentonite or diatomaceous earth is used as a filler to prevent the reaction from being too fast).
[0049] In addition, the fixed cover 11 is provided with an external exhaust hole for releasing the internal pressure and gas. The gas is collected by the built-in cotton ball. After the heat is generated, it is transferred to the position of the bottle sticker part 6 through the heat transfer plate 4. It should be noted that the bottle sticker part 6 has multiple parts, which are equidistantly distributed at the position of the built-in metal plate 64. The heat transfer plate 4 is preferably a copper sheet with a fast heat conduction speed, so that the heat can be quickly transferred to the position of the built-in metal plate 64. Since the heat generated by the above scheme can reach a higher temperature, a part of the heat loss is guaranteed, so that the temperature transferred to the bottle body is about 50 degrees, so that the paraffin melts, and then maintains a temperature of about 45 degrees. Together with the heat loss and the heat loss in the infusion, the temperature entering the human body is about 26 degrees. The heat source chamber 1 is isolated from the bottle body by the insulation board 5, and the insulation board 5 is provided with a vacuum cavity to avoid excessive heat transfer.
[0050] Paraffin 66 phase change materials (PCM) absorb / release latent heat during the solid-liquid phase change. By precisely selecting the carbon chain length of the paraffin (which determines the phase change temperature), constant temperature control can be achieved within the target temperature range (e.g. 37-45°C).
[0051] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
