Abstract
The utility model relates to an infusion tube heating and heat-preserving jacket. The infusion tube heating and heat-preserving jacket comprises a heating component and a temperature control device. An infusion tube is wrapped in the heating component which is connected with the temperature control device. The heating component is an elastic insulating sleeve. An opening is manufactured in the central axis position of one side in the radial direction of the insulating sleeve. The height of the opening is smaller than the diameter of an inner hole of the insulating sleeve. A resistive heater is axially installed in the wall of the insulating sleeve. The resistive heater is of an open shape in the radial direction and is coaxial with the insulating sleeve. A temperature sensing element is installed on one side wall of the insulating sleeve and connected with the resistive heater and the temperature control device. As the insulating sleeve of the infusion tube heating and heat-preserving jacket is integrally made of silica gel, the infusion tube heating and heat-preserving jacket has the advantages of being soft, light in weight and free of damage to the infusion tube. Furthermore, as the silica gel has elasticity and is wrapped tight around the infusion tube, the infusion tube will not be easily pulled out.
Description
Technical field

Background technology
Venous transfusion is a kind of common medical measure, in cold winter during to intravenous injection of patient, because the temperature of medicinal liquid is lower than the body temperature of human body, colder injection enters patient's blood vessel, patient is not felt well, bring misery to weakling and severe disease person, serious other symptom that also can cause.
By retrieval, Chinese patent (CN101306214A) discloses a kind of heater for transfusion tube, comprise the heater circuit that is provided with battery, heating wire composition in insulation shell, switch, described insulation shell, between them, be electrically connected to each other, and be electrically connected with described switch, its insulation shell is divided into left shell and right shell body, left shell and right shell body are hinged, on respect to one another of left shell and right shell body, heating chamber is set, described heating wire is positioned near this heating chamber, its heating chamber cross section is circular, suitable with tube for transfusion profile.
Chinese patent (CN202505910U) discloses the fixing heating apparatus of a kind of integrated infusion, comprise fixing head, described fixing head upper surface is indent arc, a side at described fixing head is provided with fixing band, be provided with the snap close matching with fixing band at the opposite side of described fixing head, be provided with calandria in described fixing head inside, be provided with transfusion tube seat in the lower periphery of described fixing head.
Above-mentioned two sections of existing problems of patent are: heater Heavy Weight, inflexible, mobile inconvenient after tube for transfusion is stuck, encounter after tube for transfusion because tube for transfusion is fixed because of carelessness, syringe needle is easy to be drawn out.
Chinese patent (CN202526720U) discloses a kind of infusion heating pipe, comprises and is close to the spirally-wound hollow looped pipeline of tube for transfusion supervisor, by adding hot water to realize the heat effect to transfusion supervisor in looped pipeline.
Chinese patent (CN203169753U) discloses a kind of tube for transfusion heating jacket, it comprises flexible cloth, is fixedly arranged on heating tube, micropump and water heater on flexible cloth inner side, heating tube is snakelike layout in flexible cloth, the water inlet of heating tube is communicated with the outlet of micropump, the water inlet of micropump is connected with the outlet pipe of water heater, and the outlet of heating tube is connected with the water inlet of water heater.
Above-mentioned two sections of existing problems of patent are: be all to carry out heating transfusion pipe by heating water, rate of warming is slow, and temperature control is difficult for regulating.
And the ubiquitous shortcoming of above-mentioned several sections of patents is that the heating surface area of tube for transfusion is limited, can only, to a bit of heated for controlling temperature that carries out of tube for transfusion, can not spread all over whole tube for transfusion.
Also not retrieving at present Patents can address the above problem simultaneously.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provide a kind of simple and reasonable, quality light, soft, heating surface area is large, the tube for transfusion heating and thermal insulation cover that heating and thermal insulation efficiency is high, effective.
The technical scheme that this utility model technical solution problem adopts is:
A kind of tube for transfusion heating and thermal insulation cover, comprise heater block and temperature regulating device, heater block is coated on outside tube for transfusion, and be connected with temperature regulating device, described heater block is an elastic insulated sleeve, opening is made at a radially side axis position of this insulated sleeve, and the height of this opening is less than the diameter of bore of insulated sleeve; In the tube wall of insulated sleeve, be axially installed with resistive heater, this resistive heater is opening shape coaxial with insulated sleeve diametrically; On the tube wall of a side of insulated sleeve, temperature-sensing element is installed, this temperature-sensing element is connected with resistive heater and temperature regulating device.
And described resistance wire adopts netted resistance wire.
And described tube for transfusion is coated on by the elasticity of insulated sleeve in the endoporus of insulated sleeve, the uniform insulation micelle projection that is shaped with on the tube wall inner edge of insulated sleeve.
Advantage of the present utility model and good effect are:
1, the insulated sleeve of this muff adopts silica gel to be made into integration, and is characterized in soft, quality is light, does not hinder tube for transfusion, and because silica gel material is flexible, it to tube for transfusion parcel closely, can not pulled out easily.
2, the insulated sleeve length of this muff is long, so the heating surface area of tube for transfusion is large, firing rate is fast, high insulating effect.
3, the resistance wire of this muff adopts netted resistance wire, with respect to traditional strip resistance silk, conducts heat more even, further makes the temperature control of this muff obtain more accurate.
4, this muff uniform insulation micelle projection that is shaped with on the inner wall of insulated sleeve, has increased the frictional force between tube for transfusion and insulated sleeve, prevents relative sliding between tube for transfusion and insulated sleeve.
