Portable drip injection device

The invention relates to a portable drip injection device; in particular, to an auxiliary device that can be carried as an injection drip, the device can accurately control the flow rate of the drip injection regardless of the posture change or posture change of the injected patient.

In recent years, through the use of sensing technology to improve the problem of spot injection, so that the injection can be safer related to the creation, such as the nationally announced patent: "arteriovenous infusion permeate detection system and its method" (2010/01/01 , I318888), "Non-contact liquid level sensor" (2009/12/11, M370413), "Drip liquid level detector" (2009/07/11, M360703), "Wireless drip warning device" (2009) /02/21, M351086), "Drip Detection Device" (2008/12/21, M347192), "Drip Injection Detection Device" (2008/12/21, M347191), "Drip Structure" (2008/12/ 21, M347190), "Drip Structure" (2008/12/01, M345608), "Drip Detection Warning Device" (2008/06/01, M333191).

In addition, through the improvement of components to improve the problem of drip injection, the drip injection can be more convenient related to the creation, such as the nationally announced patent: "active drip injection device" (2011/05/21, M404020), "drip bag export Enhanced protective sleeve for tubes" (2010/05/01, M379441), "Portable cartridge structure for intravenous drip injection devices" (2010/04/21, M378751), "Under the measuring cylinder and under the measuring cylinder Covered infusion set" (2010/04/01, M377226), "Portable "Drop-pressure injection device" (2009/11/11, M368452), "portable active drip infusion device" (2009/08/01, I312693), "fluid stop device" (2009/07/11, M360700) , "soft bag anti-pinning structure" (2009/06/21, M359330), "metering cylinder stop valve and infusion set with metering cylinder stop valve" (2009/06/11, M358645), "Drip line "Liner" (2009/03/11, M352374), "No Power Constant Temperature Drop Device" (2009/02/01, M349777), "Automatic Pushing Syringe Quantitative Syringe" (2008/12/01, M345607), " Portable environmentally friendly syringe with voltage regulation effect (2008/01/21, M325835).

In addition to the above-mentioned inventions and new patents, the problem of drip injection is improved by improving the heavy body, so that the drip injection can be more effective in related creation, such as the patent issued in the country: "The export of the drip bag" (2009/ 10/01, D131126), "Drip Bag" (2009/05/21, D128889), "Drip Bag" (2009/05/21, D128888), "Drip Bag" (2009/01/11, D127067) ), "Drip bag" (2008/04/11, D122483), "Drip bag" (2008/01/11, D121042).

Devices related to drip injection are known, for example, through sensing technology as a liquid level change in a drip bottle, thereby detecting the remaining amount of the drip injection or having a warning function, so that the drip injection has high safety. In addition, through the improvement and improvement of the current injection components, in order to improve the patient's autonomy and mobility, and to reduce the burden associated with the drip bottle, the drip injection has better convenience. Finally, the key drop bag can have a novel and unique style. By aesthetically designing the shape of the drip bag, it can show the visual beauty that was not available in the prior art, so that the drip injection possesses superior performance. However, the customary creations are all aimed at improving the current drip-hanging injection method, and there is no substantial change in the inconvenience caused by the drip injection. good. Therefore, there is a need to develop a small, low-cost, and simple operation, which can provide a long-term, high-precision and portable drip injection device using a mobile power source.

The portable drip injection device of the present invention comprises an injection unit and a casing unit, wherein the injection unit can select the peristaltic pump at different operating speeds according to the needs of the injection patient, so as to obtain precision. The amount of drip shot.

The effect of the present invention can provide accurate drip injection amount, and a portable drip injection device, which can not only make the action of the drip injection patient not restrained, but also enable the injected patient to receive a more accurate drip injection amount. It can alleviate the pressure on nursing staff and caregivers, and more importantly, to enable medical patients to receive medical dignity.
