Abstract

The utility model relates to a transfusion heater, which belongs to the technical field of a medical instrument and comprises a box body composed of an upper part and a lower part, heating elements arranged in the box body and heat exchanger plates close to the heating elements, wherein the upper box body is connected with the lower box body through a switching hinge, the heat exchanger plates of the upper and the lower box bodies can be mutually attached to each other, one of the upper and the lower box bodies is provided with an electrical connector; a concave slot containing a transfusion pipe penetrates through both ends of the box body and is respectively arranged on the heat exchanger plates; the upper box body and the lower box body are provided with electrode plates, and the electrodes on the electrode plates are mutually attached each other and are respectively electrically connected with the heating elements in the upper and the lower box bodies. The transfusion pipes are inlaid in the concave slots, after the box body is closed, the power supply is inserted and connected with the box body, and the transfusion pipes can be steadily held in the upper and the lower heat exchanger plates of the box body and is warmed by the upper and the lower heating element which are simultaneously electric. The utility model has the advantages of simple and compact structure, convenient operation and use and can meet various use requirements.

Description

Infusion warmer

Technical field

This utility model relates to a kind of transfusion additional device, and especially a kind of infusion warmer belongs to technical field of medical instruments.

Background technology

Venous transfusion is the medical procedure of using always.In order to eliminate the patient because of the low discomfort that produces of transfusion temperature, retrieve up-to-date patent and find, application number is that 03252342.4 Chinese patent application discloses a kind of " little heater of infusing ", and this device is installed heating element heater in housing, hot plate is arranged on housing, and heating element heater is pressed close to hot plate.The groove that can contain tube for transfusion is set on the heating surface of hot plate.Housing is made up of upper and lower two parts, and the hot plate on two housings can be fitted mutually, synthetic 1 the sub-circular passage of the groove of two corresponding approximate half-circular.Temperature element is set in housing, and inner cover.Patient utilize this device to regulate the temperature of transfusion as required, so that can be received treatment under comfortable situation.The applicant recognizes in practice, above prior art constructions and the equal more complicated of wiring, and volume is bigger, and the thermal efficiency is not high enough, and is not easy to settle fixing.

Summary of the invention

The technical problems to be solved in the utility model is: at the shortcoming that above prior art exists, propose a kind of simple in structure, heating effect good, and volume small and exquisite, settle infusion warmer easily.

In order to solve above technical problem, infusion warmer of the present utility model comprises upper and lower box body dimerous, be placed in the intravital heater element of box, press close to the heat transfer plate of heater element, described upper and lower box body connects by the folding hinge, the heat transfer plate of described upper and lower box body can be fitted mutually, and its improvements are: one of described upper and lower box body is equipped with electrical connector, and has the containing tube for transfusion groove that runs through the box body two ends on the heat transfer plate; Described upper and lower box body also is equipped with battery lead plate, and the electrode on the described battery lead plate can be fitted mutually, and is electrically connected with the intravital heater element of upper and lower box respectively.Tube for transfusion is embedded in the groove, closed box and peg graft to go up power supply after, tube for transfusion just is clamped in the upper and lower heat transfer plate of box body steadily, by upper and lower simultaneously electric heater element is heated, make the liquid of output have the temperature approaching with body temperature.

The further improvement of this utility model is that the groove on the described heat transfer plate presents the circuitous shape of S shape.Can make tube for transfusion that the longer length of heating is arranged in box body like this, thus even, when liquid droping speed very fast also fully heating transfusion lower in ambient temperature.

This utility model further improve be the circuitous groove of described S shape have short slot into and out of near the section, thereby higher in ambient temperature, when liquid droping speed is slow, tube for transfusion can be embedded on the heat transfer plate along short slot, suitably shorten the length of heating.

Obviously, no matter this utility model is box body structure, or electric connection structure, all simple compact, and easy for operation, can satisfy various user demands.

Description of drawings

Below in conjunction with accompanying drawing this utility model is further described.

Fig. 1 is the structural representation of an embodiment of this utility model.

Fig. 2 is the vertical view of Fig. 1 lower box body.

The specific embodiment

Embodiment one

The infusion warmer of present embodiment as depicted in figs. 1 and 2, upper cartridge body 1 ' is connected by folding hinge 2 with lower box body 1, constitutes box body component.Heater element is upper and lower infrared film electric heating cloth 3 ', 3, is placed in respectively in the upper and lower box body, presses close to upper and lower infrared film electric heating cloth 3 ', 3 the upper and lower heat transfer plate 4 ', 4 of silicone rubber is fixed in the upper and lower box body, can fit mutually.One end of lower box body 2 is equipped with by lead and the socket 6 that following infrared film electric heating cloth 3 is electrically connected, and has the containing tube for transfusion groove 7 that runs through lower box body 1 two ends on the following heat transfer plate 4, and this groove presents the circuitous shape of S shape, into and out of having short slot 8 near the section.Upper and lower box body 1 ', an end of 1 are fixed with upper and lower battery lead plate 10 ', 10 respectively, upper and lower electrode 9 ', 9 on two battery lead plates is electrically connected with the intravital nearly upper and lower infrared film electric heating cloth 3 ', 3 of upper and lower box respectively, can fit mutually when box body is closed.

During use, tube for transfusion is embedded in the groove, ambient temperature is lower, be embedded in when liquid droping speed is very fast in the circuitous groove of S shape; Ambient temperature is higher, when liquid droping speed is slow, be embedded on the heat transfer plate along short slot.Afterwards, closed box, and after peg graft going up power supply, tube for transfusion just is clamped in the upper and lower heat transfer plate of box body steadily, by upper and lower simultaneously electric heater element is heated, the output liquid that output temperature suits satisfies patient's treatment needs.

The infusion warmer that experiment showed, present embodiment is simple in structure, and volume is small and exquisite, cost economy, and thermal efficiency height portably uses conveniently.

In addition to the implementation, this utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of this utility model requirement.
