Abstract
The invention discloses a high-molecular PTC heating infusion device. The device comprises an infusion tube, wherein a bottle insert needle, a dropping cylinder, a flow regulator and a constant-temperature heating sleeve are sequentially arranged along the infusion tube from top to bottom; the constant-temperature heating sleeve comprises an insulation layer, a heating layer and a heat transfer layer, and the insulation layer, the heating layer and the heat transfer layer sequentially coat the casing of the infusion tube from outside to inside; the inside of the insulation layer is of a honeycomb shape; and an electrifying contactor is arranged on the constant-temperature heating sleeve. The high-molecular PTC heating infusion device has the beneficial effects that, due to the arrangement of the constant-temperature heating sleeve, a drug solution or blood device passing through an infusion catheter is firstly heated and enters a patient body, so that the infused solution is similar to the temperature of the body temperature, the adverse response caused by blood and solution transfusion of a low-temperature solution can be completely eliminated; and the constant-temperature heating sleeve is made from high-molecular PTC, so that the temperature stability is easy to control.
Description
Technical field
The invention belongs to a kind of medical Transfusion device, particularly relate to the transfusion device of a kind of heated at constant temperature.
Background technology
At present, in the clinical transfusion transfusion procedure of hospital, it is common that complete with transfusion device, but existing transfusion device is all without heating function.Owing to institute's loading liquid or blood product are usually preservation in Ba Wen environment, therefore during transfusion and blood transfusion, enter medicinal liquid in the patient or blood plasma be relatively cold state significantly lower than the liquid of body temperature, so be easily caused patient produce such as vasospasm, shiver, the blood transfusion and infusion reaction such as heating, particularly with infant and old patient, and need infuse in a large number in short-term or need the patient of prolonged operations more prominent and more notable in cold season.
Summary of the invention
The technical problem to be solved is to provide a kind of heating infusion device that can guarantee that institute's transfusion and body temperature are close.
For solving the problems referred to above, the technical scheme is that, a kind of high molecular PTC heating infusion device, including tube for transfusion；Needle for inserting bottle, drop cylinder, flow regulator and constant-temperature heating sleeve it is disposed with from top to bottom along tube for transfusion；Described constant-temperature heating sleeve includes heat-insulation layer, zone of heating and heat transfer layer, and described heat-insulation layer, zone of heating and heat transfer layer are wrapped on the crust of tube for transfusion from outside to inside successively；The inside of described heat-insulation layer becomes cellular；Described constant-temperature heating sleeve is provided with energising feeler.
Further, described zone of heating is made up of PTC.
Further, described heat transfer layer has masking foil to constitute.
Further, the middle part of described needle for inserting bottle is provided with catch, and the bottom of catch is provided with draw ring.
Further, bonded together by adiabatic gum between described heat-insulation layer and zone of heating.
Beneficial effects of the present invention: owing to being provided with constant-temperature heating sleeve on tube for transfusion, patient's body is entered after making the medicinal liquid by transfusion catheter or blood device first be heated, ensure that institute's transfusion and body temperature are close, completely eliminate the blood transfusion and infusion untoward reaction produced because of cryogenic liquid.Constant-temperature heating sleeve high molecular PTC is constituted simultaneously, and temperature stabilization is easily controlled.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the sectional structure schematic diagram of A-A.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further elaborated.
As illustrated in fig. 1 and 2, a kind of high molecular PTC heating infusion device, including tube for transfusion 2；Needle for inserting bottle 1, drop cylinder 5, flow regulator 3 and constant-temperature heating sleeve 4 it is disposed with from top to bottom along tube for transfusion 2；Heater and transfusion device are organically combined as a whole, patient's body is entered after making the medicinal liquid by transfusion catheter or blood device first be heated, ensure that institute's transfusion and body temperature are close, completely eliminate the blood transfusion and infusion reaction produced because of cryogenic liquid, particularly with infant and elderly and infirm and need infuse in a large number in short-term or need the patient of prolonged operations more applicable.
Simultaneously in order to better ensure thermal diffusion, constant-temperature heating sleeve 4 includes heat-insulation layer 4.1, zone of heating 4.2 and heat transfer layer 4.3, and described heat-insulation layer 4.1, zone of heating 4.2 and heat transfer layer 4.3 are wrapped on the crust of tube for transfusion 2 from outside to inside successively；The inside of described heat-insulation layer 4.1 becomes cellular；Described constant-temperature heating sleeve 4 is provided with energising feeler, and heat transfer layer 4.3 has masking foil to constitute.Zone of heating 4.2 processes by extruding with PTC macromolecular material, and temperature stabilization is easily controlled.The middle part of needle for inserting bottle 1 is provided with catch 1.1, and the bottom of catch 1.1 is provided with draw ring 1.2.Present configuration is simple, volume is little, lightweight, cost is low, easy to use, and its heating-up temperature is from limitting constant temperature, owing to tube for transfusion being provided with constant-temperature heating sleeve, patient's body is entered, it is ensured that institute's transfusion is close with body temperature, completely eliminates the blood transfusion and infusion untoward reaction produced because of cryogenic liquid after making the medicinal liquid by transfusion catheter or blood device first be heated.
Those of ordinary skill in the art is it will be appreciated that embodiment described here is to aid in reader understanding's principles of the invention, it should be understood that protection scope of the present invention is not limited to such special statement and embodiment.Those of ordinary skill in the art can make various other various concrete deformation and combination without departing from essence of the present invention according to these technology disclosed by the invention enlightenment, and these deformation and combination remain in protection scope of the present invention.
