Description
本發明涉及一種加熱器，特別係涉及一種注射器用之加熱器。 The present invention relates to a heater, and more particularly to a heater for a syringe.
在一些醫療操作過程中，如在家庭、醫院、化驗室實施之門診外科手術，病人輸液管理至關重要。在醫院實施之外科手術中，保持病人體溫有一定原則及技術標準，尤其係在手術前、手術中及手術後之各階段，病人體溫應該保持在正常生理體溫，以避免出現體溫過低及各種併發症，如麻醉恢復延遲及需氧量增加，出現肌肉抽搐引發之血氧低下症等。考慮到以上因素，一些醫療操作中通常對靜脈注射給液進行加熱，以便將注射給液之溫度保持在病人合理之生理溫度。 In some medical procedures, such as outpatient surgery performed in homes, hospitals, and laboratories, patient infusion management is critical. In the implementation of external surgery in hospitals, there are certain principles and technical standards for maintaining the patient's body temperature, especially in all stages before, during and after surgery. The patient's body temperature should be kept at a normal physiological temperature to avoid hypothermia and various Complications, such as delayed recovery of anesthesia and increased oxygen demand, hypoxemia caused by muscle twitching. In view of the above factors, intravenous fluids are usually heated in some medical procedures to maintain the temperature of the injected fluid at a reasonable physiological temperature for the patient.
目前大多數情況下採用熱水袋或熱毛巾熱敷直接壓在輸液管上以使注射給液升溫。這種方法會使注射給液溫度不穩定，當溫度過高時，會使有些注射給液中之藥物分解，而且使用時需頻繁更換該熱水袋或熱毛巾，很不方便。 In most cases, hot water bags or hot towel hot packs are directly pressed onto the infusion tube to warm the injection solution. This method will make the temperature of the injection solution unstable. When the temperature is too high, some of the drugs in the injection solution will be decomposed, and the hot water bottle or the hot towel needs to be frequently replaced during use, which is inconvenient.
有鑒於此，有必要提供一種簡單方便，加熱穩定之注射器用之加熱器。 In view of this, it is necessary to provide a heater for a syringe that is simple and convenient to heat and stabilize.

相較於先前技術，本發明所提供之注射器用加熱器可以直接將其本體固定於注射給液之包裝容器或包裝袋上，或者係輸液管上，從而為注射給液加熱。由於當給加熱元件通以電流時，該加熱元件之電阻不變，通常電壓也不變，所以該加熱器所產生之熱量係恒定，進而使得注射給液之加熱溫度恒定，達到醫學上所要求之注射給液加熱之技術標準。同時，該加熱器只要有電源便可以使用，不用頻繁更換，使用簡單方便。 Compared with the prior art, the heater for a syringe provided by the present invention can directly fix its body to a packaging container or a package for injecting liquid, or to an infusion tube to heat the injection solution. Since the resistance of the heating element does not change when the current is applied to the heating element, and generally the voltage does not change, the heat generated by the heater is constant, so that the heating temperature of the injection liquid is constant, which is medically required. The technical standard for the injection of liquid heating. At the same time, the heater can be used as long as it has a power supply, and it is easy to use without frequent replacement.

The nano carbon pipeline and the preparation method thereof can be referred to the application of Fan Shoushan et al. on September 16, 2002, and the Chinese Patent No. CN100411979C, which was announced on August 20, 2008, "a nano carbon tube rope and its Manufacturing method", Applicant: Tsinghua University, Hongfujin Precision Industry (Shenzhen) Co., Ltd., and China Patent Application No. CN1982209A, published on June 20, 2007, "Nano Carbon Tube Wire and Its Manufacturing Method", Applicant: Tsinghua University, Hongfujin Precision Industry (Shenzhen) Co., Ltd. In order to save space, only the above is cited, but all the technical disclosures of the above application are also considered as part of the technical disclosure of the present application.
可以理解的是，所述加熱元件111也可以包括複數上述之非扭轉之奈米碳管線和扭轉之奈米碳管線通過編織或者交叉方式鋪設在本體10之表面上或設置在本體10之內部。 It can be understood that the heating element 111 can also include a plurality of the above-mentioned non-twisted nano carbon pipelines and twisted nanocarbon pipelines laid on the surface of the body 10 or disposed inside the body 10 by weaving or crossover.
在本實施例中，所述加熱元件111為一層狀奈米碳管結構，其包括複數層奈 米碳管膜層疊設置。奈米碳管在該層狀奈米碳管結構中沿同一方向擇優取向排列，即每層奈米碳管膜中之奈米碳管之排列方向相同。優選地，所述該層狀奈米碳管結構之厚度為100微米。該層狀奈米碳管結構為正方形，其長度和寬度均為18厘米。 In this embodiment, the heating element 111 is a layered carbon nanotube structure including a plurality of layers. The carbon tube film is laminated. The carbon nanotubes are arranged in the same direction in the layered carbon nanotube structure, that is, the arrangement of the carbon nanotubes in each layer of the carbon nanotube film is the same. Preferably, the layered carbon nanotube structure has a thickness of 100 microns. The layered carbon nanotube structure is square and has a length and width of 18 cm.
可以理解的是，由於奈米碳管膜與奈米碳管線具有較好之柔韌性，經複數次彎折也不會損壞其結構，當所述本體10也由柔性材料制得時，該加熱器100便可以成為一柔性加熱器，其可以任意折疊，方便攜帶。在使用時，還可以方便地包覆在注射給液之包裝容器或包裝袋或者係輸液管之外面。 It can be understood that since the carbon nanotube film and the nano carbon pipeline have better flexibility, the structure is not damaged by a plurality of bending, and when the body 10 is also made of a flexible material, the heating is performed.

In use, it can also be conveniently coated on the outside of the packaging container or packaging bag for injecting liquid or the infusion tube.
另外，當層狀奈米碳管結構之厚度比較小時，例如小於10微米時，該層狀奈米碳管結構即會有很好之透明度，其透光率可以達到95%。同樣之道理，當該線狀奈米碳管結構之直徑小於10微米時，其透明度也可以達到95%。當然可以理解的是，當線狀奈米碳管結構為非透明時，還可以通過調整該線狀奈米碳管結構之間之距離，使其所占本體10之面積僅為本體10總面積之一小部分，從而可以得到一透明之加熱元件111。所述第一、第二電極112、113也用透明材料制得，如銦錫金屬氧化物或者層狀奈米碳管結構或線狀奈米碳管結構。所述本體10也由透明材料制得，如亞克力、聚丙烯、聚乙烯、聚氨酯以及聚碳酸酯等。便可以得到一透明之加熱器100。 In addition, when the thickness of the layered carbon nanotube structure is relatively small, for example, less than 10 μm, the layered carbon nanotube structure has a good transparency, and the light transmittance can reach 95%. By the same token, when the diameter of the linear carbon nanotube structure is less than 10 μm, the transparency can reach 95%. Of course, it can be understood that when the linear carbon nanotube structure is opaque, the distance between the linear carbon nanotube structures can be adjusted to make the area of the body 10 only the total area of the body 10. A small portion allows a transparent heating element 111 to be obtained. The first and second electrodes 112, 113 are also made of a transparent material such as an indium tin metal oxide or a layered carbon nanotube structure or a linear carbon nanotube structure. The body 10 is also made of a transparent material such as acrylic, polypropylene, polyethylene, polyurethane, polycarbonate, and the like. A transparent heater 100 can be obtained.

請參閱圖7，為本發明第二實施例所提供之注射器用之加熱器200。所述加熱器200包括一個本體20，一個設置於本體20內部之加熱模組21。所述加熱模組21包括一個加熱元件211，複數第一電極212，複數第二電極213。所述複數第一電極212及複數第二電極213交替間隔設置並分別與所述加熱元件211電連接。 Please refer to FIG. 7, which is a heater 200 for a syringe according to a second embodiment of the present invention.

所述加熱模組21與本體20一體成型，即指將加熱元件211以及所述複數第一、第二電極212、213嵌入到本體10中，而僅將複數第一、第二電極212、213部分露於本體20之外或通過導線(圖未示)將第一、第二電極212、213電連接於加熱器200之外部以利於連接外部電源。在本實施例中，所述複數第一電極212通過第一導線22並聯電連接，從而形成一個第一插齒電極。所述複數第二電及213通過一第二導線23並聯電連接，從而形成一個第二插齒電極。 The heating module 21 is integrally formed with the body 20, that is, the heating element 211 and the plurality of first and second electrodes 212 and 213 are embedded in the body 10, and only the first and second electrodes 212 and 213 are plural. The first and second electrodes 212, 213 are partially exposed outside the body 20 or electrically connected to the outside of the heater 200 by wires (not shown) to facilitate connection of an external power source.

The three first electrodes 212 and the three second electrodes 213 and the first and second wires 22, 23 form two "mountain" structures, which respectively comprise three "teeth". It will of course be understood that the first and second electrodes 212, 213 may also include more "teeth" when the volume of the heater 200 is large. The plurality of first electrodes 212 and the plurality of second electrodes 213 are alternately and intermittently insulated to form a structure in which the positive and negative electrodes are alternately arranged to facilitate uniform power supply to the heating element 211, thereby further heating the heating element 211. A lead post 214, 215 is further disposed on the first and second electrodes 212, 213 for electrically connecting the first and second electrodes 212, 213 to the external power source through the wires. It can be understood that, since the heater 200 has a plurality of first and second electrodes 212 and 213, the overall resistance of the heater 200 can be lowered, so that the operating voltage can be lowered, thereby enabling the heater 200 to operate at a safe voltage. Such as 36 volts.
