Description

Four limbs muff

Technical field

The present invention relates to a kind of muff, and in particular to a kind of four limbs muff, belongs to technical field of medical auxiliary equipment.

Background technology

With the raising of surgery operating technology, many operations had been absolute contraindication in the past, and the now is into respect to taboo Disease even indication so that the quantity of surgical operation is also to increase year by year.It is well known that patient body heat in operation Loss do not solved well all the time, warm saline seems to alleviate some heat instead of normal temperature normal saline washing in prior art The loss of amount, but that is an utterly inadequate amount.Learnt by consulting literatures, heat loss through radiation（thermal radiation）Refer to people Body heat is transmitted to a kind of extraneous radiating mode compared with solidifiable substance by body in the form of heat ray.Human body in 21 DEG C or so of environment, （The namely universal temperature of operating room）In the case of nude, the heat that there are about 60% is dissipated by radiation mode.Radiation dissipates Heat number depend primarily on two aspect：On the one hand, the temperature difference between the skin of patient and surrounding environment, works as skin temperature During higher than environment temperature, temperature difference is bigger, and heat dissipation capacity is more.If we are too high by the temperature adjustment of operating room, reducing Really effect is served in terms of patient irradiation's radiating, but when temperature is too high, operator tends to have sultry, perspiration, fidgety, tired etc. Reaction, stable mood and quick thinking are easily influenceed, prevents the technical merit of operator from being played well.Simultaneously Patient also occurs the symptoms such as heart rate is fast, perspiration is more and increases operating difficulty, and the too high growth for being also easily caused bacterium of temperature is unfavorable In the sterile of operating field.On the other hand, heat loss through radiation additionally depends on effective area of dissipation of body, and effective area of dissipation is bigger, Heat dissipation capacity is more.Because the surface area of four limbs is larger, thus played an important role in heat loss through radiation.Calculated according to rule of Nine Body surface area, bilateral forearm, upper arm, and bilateral thigh, the area percentage of whole body shared by shank are 7+6+21+13=47%. And it is current, we can only be lost using heat keeper to reduce the heat at patient back, and back only accounts for the 13% of body surface area, Comparatively speaking, the heat compared with four limbs, which is lost, wants much less.It is incubated in addition, heat keeper is the hot-air being full of by inside, Once local compression, air compression, there is the problem of heat transfer is uneven.The air pump inflated to heat keeper is also larger more expensive Weight, it is impossible to freely moved with the transhipment of patient, therefore, be badly in need of design and want a kind of easy to use, and be easy to regulation heating temperature The four limbs muff of degree.

Embodiment 2

As shown in Fig. 6,7,8,9,10,11, the difference of embodiment 2 and embodiment 1 is：One kind is entered suitable for human upper limb The four limbs muff of row insulation, the body 1 are provided with garter window 1-4, and this is for the ease of having an acupuncture treatment the arm of patient.When So, the present invention can also be coated on arm again after patient has an acupuncture treatment.

The present invention is before use, as shown in Figure 4,5, the muff suitable for human body lower limbs to be coated on to the leg of patient, so The heat-conducting layer 1-2 and a flame-retardant layer 2 of heating unit 1-1 sides a surface bonding connection afterwards, as shown in figure 9, will The arm of patient, the side of heat-conducting layer and the side bonding connection of thermal insulation layer are coated on suitable for the muff of human upper limb.

The present invention the course of work be：In use, assembly 4-3 control heating units 1-1 heating is controlled by temperature adjustment Temperature, heating unit 1-1 heating-up temperature is regulated and controled by temperature adjustment knob 4-3-4, and is shown by display circuit 4-3-3, The temperature sensor 4-4 collections heating-up temperature as corresponding to every group of heating tributary unit, according to the demand of patient, if heating is single First 1-1's is too high or too low for temperature, can control assembly 4-3 temperature adjustment knob 4-3-4 regulation heating single by temperature adjustment First 1-1 heating-up temperature；

As shown in figure 12, the DC power-supply circuit 4- to be powered by the voltage monitoring circuit 4-3-21 to every group of heating tributary unit 3-1 carries out voltage acquisition, if one DC power-supply circuit 4-3-1 of any of which occurs under-voltage, exports under-voltage signal immediately and arrives Single-chip microcomputer 4-3-5, and by single-chip microcomputer 4-3-5 output control signals, the 4-3-6 alarms of control alarm unit；

Reference voltage Vref in Figure 12 is divided into three voltage references by resistor network, respectively as each direct current supply electricity Road 4-3-1（Lithium battery）Reference data.By taking lithium ion battery B3 as an example, when its voltage is less than its brownout threshold, through electricity Hinder Rj and Rk partial pressure compared with voltage on resistance Rn, comparator UgD actions, export high level, i.e., it is under-voltage Signal UV_Sig is sent to central control unit.Show that the branched battery is under-voltage on a display screen simultaneously.

As shown in figure 13, the electric current of every group of heating tributary unit is adopted in real time by the current monitoring circuit 4-3-22 Sample, when output current exceedes the reference value set in single-chip microcomputer 4-3-5, over-current signal is admitted to single-chip microcomputer 4-3-5, and defeated Go out control signal and forbid the output of the heating tributary unit, and control alarm unit 4-3-6 to alarm；

RL is the load of output end access in Figure 13, and Vref is voltage reference value.Limited when the electric current of output exceedes, i.e., it is electric Voltage on stream sampling resistor Rsense exceedes reference value Vref so that comparator acts, by optocoupler over-current signal OC_ Sig is admitted to single-chip microcomputer 4-3-5, and optocoupler causes output and control circuit to keep apart, enhances security performance.

Display circuit 4-3-3 of the present invention is capable of the state of every group of heating tributary unit of real-time display, i.e., each branch road Whether heating-up temperature, operating voltage, the output current of each output circuit, each branch export.Basis is actually needed adjustment output simultaneously Pulse, to adjust the heat time.

The present invention is not only easy to use, and is easy to adjust heating-up temperature, and is dropped significantly by the insulation to four limbs The heat of low patients during peri is lost, and reduces the generation of postoperative hypothermia, effectively facilitates quick recovery and applied in clinic.

It is complete by above-mentioned description, relevant staff using the above-mentioned desirable embodiment according to the present invention as enlightenment Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention Property scope is not limited to the content on specification, it is necessary to determines its technical scope according to right.
