Abstract

The invention discloses a high-polymer PTC adjustable heating type infusion apparatus which comprises an infusion tube, wherein a bottle inserting needle, a drip tube, a flow adjuster and a constant temperature heating jacket are sequentially arranged along the infusion tube from top to bottom; the constant temperature heating jacket comprises an insulating layer, a heating layer and a heat transfer layer, and the insulating layer, the heating layer and the heat transfer layer are sequentially coated on the outer wall of the infusion tube from outside to inside; a heating switch is arranged on the flow adjuster and is electrically connected with the heating layer; and a temperature control module and a power switch are arranged in the heating switch. The high-polymer PTC adjustable heating type infusion apparatus has the beneficial effects that because the constant temperature heating jacket is arranged on the infusion tube, a liquid medicine or blood maker passing through the infusion tube is firstly heated and then enters the body of a patient; and meanwhile, the heating switch is arranged on the flow adjuster and is electrically connected with the heating layer, and the temperature control module and the power switch are arranged in the heating switch, so that the manual control of switch adjustment of temperature is realized.

Description

A kind of adjustable heating infusion device of high molecular PTC

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 adjustable heating infusion device of high molecular PTC, 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；Being provided with heater switch on described flow regulator, described heater switch electrically connects with zone of heating；Described heater switch is internally provided with temperature control module and on and off switch.

Further, described zone of heating is made up of PTC.

Further, described heat transfer layer has masking foil to constitute.

Further, bonded together by adiabatic gum between described heat-insulation layer and zone of heating.

Further, the centre of described heat-insulation layer is vacuum layer.

Further, described vacuum layer interior layer is cellular.

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, being provided with heater switch on described flow regulator, described heater switch electrically connects with zone of heating simultaneously；Described heater switch is internally provided with temperature control module and on and off switch, it is achieved that the Non-follow control of the switch-mode regulation of temperature.

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 adjustable heating infusion device of high molecular PTC, 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.Being provided with heater switch 6 on described flow regulator 3, described heater switch 6 electrically connects with zone of heating 4.2；Described heater switch 6 is internally provided with temperature control module 6.1 and on and off switch 6.2.Patient can be according to the actual needs, it is achieved the Non-follow control of the switch-mode regulation of temperature, and temperature control module precisely can effectively control the heating temp of zone of heating 4.2 simultaneously.

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 vacuum 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, and 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, after making the medicinal liquid by transfusion catheter or blood device first be heated, enter patient's body, it is ensured that institute's transfusion is close with body temperature.

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.
