Description

The transfusion heating box

This utility model relates to medical auxiliary apparatus.

Transfusion is one of conventional means of medical treatment and health care.Except that the period of hot summer minority, the transfusion and the human body temperature that are in room temperature state throughout the year have very big difference.This temperature difference can make and be subjected to liquid the person feels under the weather, and often causes that at transfusion pin hole place congestion is livid purple, and is old and often transfusion person is more so.Transfusion person needs repeatedly hot compress ability relief of symptoms, the patient suffering, and the doctor is helpless.

The purpose of this utility model is for addressing the above problem, design a kind of transfusion heating box, supporting use when transfusion, can make the transfusion temperature near human body temperature, eliminate the sense of discomfort that the temperature difference causes, reduce or prevent pin hole congestion, exempt or reduce hot compress number of times, useful doctor patient.

The purpose of this utility model is following realization: design a transfusion heating box that can grip tube for transfusion, it comprises box body 1, lid 1 ', PTC ceramic heat assembly 2, leading heat channel 3, heat-conducting plate 6, thermal insulation board 4, upper cover plate 5 and switch 10; Link to each other with PTC ceramic heat assembly 2 again after dominating heat channel 3 and heat-conducting plate 6 being connected.And it is middle to be installed in box body 1 by inner bolt 7; Upper cover plate 5 is installed on the box body 1 leading heat channel 3 both sides by male screw thread 8, and through thermal insulation board 4 glands on heat-conducting plate 6; Battery lead plate 9 via line in the PTC ceramic heat assembly 2 link to each other with plug 11 with switch 10.When former transfusion operation is finished but is not begun to infuse as yet, tube for transfusion is placed in the leading heat channel 3 in this utility model heating box, the lid 1 that closes ', energized and open switch 10 after, can begin equality of temperature (comparatively speaking) transfusion.

Examination is surveyed and shown: when the transfusion heating box was placed on apart from human transfusion pin hole 80-100 centimeters, the temperature that can make transfusion enter human body improved 10-15 ℃ on former temperature basis.This temperature increment can make throughout the year at ambient temperature transfusion temperature reach or near body temperature.Reduce the patient that the transfusion temperature difference causes significantly and do not accommodate pin hole congestion phenomenon, exempt or part has been exempted patient suffering and hot compress trouble, made things convenient for medical personnel's transfusion once more, good social and economic benefit are arranged.

Below in conjunction with embodiment and the auspicious this utility model of stating of accompanying drawing thereof:

Fig. 1 is this utility model surface structure sketch map;

Fig. 2 is that this utility model box body 1 is overlooked the section structure sketch map;

Fig. 3 is this utility model box body 1 side-looking section structure sketch map;

Fig. 4 is this utility model PTC ceramic heat assembly 2 local A structure for amplifying sketch maps.

This utility model adopts the box structure of side hinge joint, and purpose is for the ease of clamping tube for transfusion, the convenient use.The length of box body 1 (lid 1 ') depends on the requirement to transfusion heating-up temperature in the tube for transfusion, and width and thickness depend on the planform of PTC ceramic heat assembly 2.Satisfying under the above-mentioned requirements situation, transfusion heating box size should be as far as possible little, and meet the aesthetic feeling design.Embodiment has adopted camber line design (with reference to figure 2).Leading heat channel 3 is housed in the middle of the box body 1, tube for transfusion is heated with it.Leading heat channel 3 shapes are designed to semicircle according to the tube for transfusion external diameter, effectively transfusion is heated.For more effectively to transfusion heating, on the position of lid 1 ' corresponding with leading heat channel 3 design be equipped with the secondary thermal trough 3 that is complementary with leading heat channel 3 ', both form in lid 1 ' be fastened on box body 1 back the attaching of tube for transfusion are heated.Secondary thermal trough 3 ' thermal source rely on leading heat channel 3 contact conduction, both all adopt copper product.

Leading heat channel 3 links to each other with thermal conduction plate 6 on the PTC ceramic heat assembly 2 and is supplying heat source with the latter.Connection can be adopted welding or riveted joint.Consider that from both connected modes and conduction efficiency angle leading heat channel 3 also can be made into square.But preferred plan is the semicanal shape of interior round foreign side.Interior circular diameter and tube for transfusion diameter are complementary, and the foreign side limit can absorb the conduction heat better.Embodiment promptly adopts this planform (referring to Fig. 2).Major and minor thermal trough 3,3 ' both sides be equipped with respectively upper cover plate 5,5 ', and respectively with male screw thread 8 be fixed on box body 1 and lid 1 ' on.

It is PTC ceramic heat assembly 2 that this utility model adopts thermal source.It comprises heat-conducting plate 12, mica sheet 13, heater 14, battery lead plate 9, ceramics seat 15.The PTC ceramic heat assembly 2 of this structure is a prior art.This utility model is selected for use according to need and is got final product.The principle of selecting for use should make the transfusion temperature rise control within the specific limits, promptly can not be higher than body temperature, can not make tube for transfusion infringement (comprising when no liquid flows through), and temperature keeps reliable and stable.Designed heat-conducting plate 6 links to each other with heat-conducting plate 12 on the PTC ceramic heat assembly 2, and 9 via line of battery lead plate link to each other with plug 11 with switch 10.PTC ceramic heat assembly 2 usefulness inner bolts 7 are fixed on the box body 1.Be filled with thermal insulation board 4 between itself and the upper cover plate 5 and by latter institute gland.In order to ensure safety, the appropriate location in box body 1 also can install thermal insulation board 16 and insulation board 17 (referring to Fig. 2,3) additional.

When one group of PTC ceramic heat assembly 2 can not satisfy when adding heat request, can design 2 parallel connections of many group PTC ceramic heat assemblies.Embodiment has adopted three groups to be connected in parallel.Battery lead plate 9 in the PTC ceramic heat assembly 2 links to each other with switch by respective lines (simple parallel line, when one group of PTC ceramic heat assembly 2, circuit is more simple).When PTC ceramic heat assembly 2 was three groups, switch also should be three retaining (high, medium and low) gauge taps 10 mutually.

Use for convenience, embodiment has also designed clamp 18 (referring to Fig. 3) and transfusion heating box card can have been hung on the infusion bottle cradling piece with it in box body 1 back.Also can on box body 1, design a hook or link (not drawing among the figure), hang over during use on the infusion bottle cradling piece.

Embodiment has also designed display lamp 19 (light emitting diode) to show non-transformer.

The concrete parameter of embodiment is:

Overall dimensions: 200 * 75 * 30 (mm)

Weight: 240 (g)

Power: 220 (V), 15 (W)

Heater temperature: 260 ℃ (maximum surface temperature)

Transfusion temperature rise: 10 ℃, 12 ℃, 15 ℃ (three class).
