Medical inferior low temperature ice blanket regulatorTechnical field
This utility model relates to a kind of medical ice blanket, relates to a kind of regulator that is used for the medical inferior low temperature ice blanket of sub-low-temperature therapeutic equipment in particular.
Background technology
Discovered the neuronal damage that inferior low temperature (30 ~ 35 ℃) treatment on many links, can alleviating cerebral ischemia, anoxia cause since the eighties in 20th century; And for the critical patient of brain injury (comprise cerebrovascular, cerebral trauma, mesencephalic centre sexuality dye etc.) and continuous high temperature; Reduce temperature to stop PD extremely important; In addition needs are carried out head, local coolings such as joint part are with protection cerebral tissue, joint tissue etc., and it also is very important winning treatment time.
Sub-low-temperature therapeutic equipment is of a great variety at present, but basic structure is made up of main frame and adnexa always.Main frame can be divided into three parts on the composition structure: refrigeration system, pumping system and operation control system.Adnexa then directly contacts with the patient.The refrigerant of the temperature that requires is provided by main frame during work, refrigerant is circulated between adnexa and main frame, thereby regulate body temperature through hydraulic pump.Existing cooling adnexa is generally the ice blanket, even the ice blanket links to each other with refrigeration machine through conduit, the process refrigerant circulates and reduces the next indirect reduction patient's of ice blanket temperature inside body temperature.But because existing ice blanket generally all is nonadjustable; That is to say that mild hypothermia therapy uses the cooling of ice blanket for a long time; Can not change ice blanket shape according to the different weight patient makes the ice blanket reach best contacting with human body; Extruding degree to the excessive patient of body weight is excessive, and is difficult to keep stationary temperature.And in the use of ice blanket, also often occurred making and iced the disruptive phenomenon of blanket owing to pressure is excessive.
Summary of the invention
This utility model is to solve the technical problem that ice blanket mattress internal pressure is regulated, and a kind of medical inferior low temperature ice blanket regulator is provided.
In order to achieve the above object, the technical scheme that this utility model adopts is: a kind of medical inferior low temperature ice blanket regulator comprises refrigeration system; Ice blanket import and export pipe; The pressure adjusting device, ice blanket mattress is provided with the refrigerant circulation pipe in the ice blanket mattress; The refrigerant circulation pipe connects refrigeration system through the import and export pipe, is characterized in: the pressure adjusting device is connected through the refrigerant circulation pipe of pipe with ice blanket mattress.
The pressure adjusting device is made up of left chamber, right ventricle and elastic film; Form left chamber and right ventricle through being provided with elastic film in the middle of the inner shell of pressure adjusting device; Chamber, a left side is a sealed gas chamber, and the right ventricle is connected through the refrigerant circulation pipe of pipe with ice blanket mattress, and is full of refrigerant in the right ventricle.
The beneficial effect of this utility model is:
This utility model relies on a kind of device that can regulate ice blanket internal pressure, makes that the contact area between patient and the ice blanket mattress reaches maximization, has reduced patient's body temperature faster.When operation; Because the existence of regulator; Guaranteed that the ice blanket in use can not break because pressure is too big, also can not let the ice blanket that patient body is caused the transition extruding simultaneously, influenced the patient blood circulation; For valuable time has been striven in patient's timely rescue, also many unnecessary troubles have been removed from for the doctor.
Description of drawings
Fig. 1 is the structural representation of this utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment this utility model is further described.
As shown in Figure 1, the medical inferior low temperature ice blanket regulator of this utility model comprises refrigeration system 1, ice blanket import andexport pipe 3,2,pressure adjusting device 4,ice blanket mattress 9 etc.Be provided withrefrigerant circulation pipe 10 in theice blanket mattress 9,refrigerant circulation pipe 10 is connected refrigeration system 1 throughinlet tube 3 with outlet 2, andpressure adjusting device 4 is connected through therefrigerant circulation pipe 10 ofpipe 8 withice blanket mattress 9.
This utility model adopts pressure equal principle in linker two ends to control the pressure ofice blanket mattress 9 inside.Draw apipe 8 atice blanket mattress 9 places and link to each other withpressure regulator 4,pressure regulator 4 is made up ofleft chamber 5,right ventricle 7 and elastic film 6.When patient lay on the ice blanket, theelastic film 6 ofpressure adjusting device 4 was moved to the left, and 5 spaces, left chamber diminish, and air or gas pressure intensity raise, thus indirect adjusting the pressure ofright ventricle 7;Right ventricle 7 directly links to each other withice blanket mattress 9, the inside be full of withice blanket mattress 9 in the same refrigerant.Opened in 6 minutes by the elastic film of a sealing between the left andright Room 5,7,elastic film 6 can move according to the pressure change between two Room, so the room air ofleft chamber 5 or gas pressure intensity just equal the pressure of refrigerant in theright ventricle 7.
According to different patients' body weight, this utility model rely on intermediaryelastic film 6 move to left withleft chamber 5 in the pressure that produces control the pressure thatice blanket mattress 9 inwalls receive indirectly, to increase the effective contact area betweenice blanket mattress 9 and the patient, reach fast cooling.
After 9 adjust blood pressure of 4 pairs of ice of pressure regulator blanket mattress, can also well solving at present, disruptive problem in use takes place too greatly and easily owing to pressure inice blanket mattress 9.
Air or gas pressurized are adopted in chamber, aleft side 5, can not impact surgical environments and living environment because of air or gas leakage.
At first the body weight according to different patients adds an amount of refrigerant through refrigeration system 1 in ice blanket mattress 9.In general, the refrigerant amount that the heavier patient of body weight adds should be some more, and the refrigerant amount that the lighter patient of body weight adds should be less.Becauseright ventricle 7 links to each other withice blanket mattress 9 throughpipe 8; The inside is full of refrigerant, so when patient lies on the ice blanket, can make right ventricle's 7 refrigerant pressure rising andelastic film 6 is moved to left; The pressure of gas or air raises thereupon in thechamber 5, a left side, and final sum right ventricle pressure equates.Middleelastic film 6 has also played cushioning effect on the sick bed time on patient just lies, when regulating pressure, play balance both sides pressure action.
