Operation table

Technical field

The present invention relates to technical field of medical instruments, especially a kind ofly be used to settle patient, make patient safety, comfortable, the operation tool that allows the doctor operate simultaneously to provide smoothly.

Background technology

In order to prevent patient with operation generation hypothermia in the art, make operative doctor in operation process, be in a comfortable state simultaneously.Because the ambient temperature of operating room requires to be controlled at about 22 ℃-24 ℃ usually; the patient has creeping chill usually under the low temperature environment of operating room; in operation process; usually wild and carry out disinfection on every side with disinfectant to patient's art; the patient is under narcotism simultaneously; body temperature can decrease; add the quick convection current of room air; can increase the heat radiation of patient's body; above-mentioned multiple factor causes excessively lost the causing of patient's body heat that hypothermia takes place in the art; cause various complication, influence success rate of operation, be unfavorable for patient's early recovery.Particularly meet facility solution critical, that wound is big, the temporary nothing of the hypothermia situation of weak patient with operation is suitable accordingly.If improve room temperature by force in the art, operative doctor then can diaphoresis, scratch where it itches, and causes operation technique to proceed.The ambient temperature of operating room temperature concerning the patient is low excessively, prior art is to utilize electric blanket to be laid on the operation table bed surface, to improve patient temperature, there is following deficiency in this technical scheme: 1, electric blanket cleans, sterilizes difficult, pathogenic bacteria easily breeds, cause cross infection, be unfavorable for the work of hospital infection control; 2, may take place that a large amount of blood, body fluid flow out or it leaks electricity when aging, have bigger potential safety hazard; 3, poor temperature uniformity.

Summary of the invention

The purpose of this invention is to provide a kind of operation table, this operation table can solve operating room in the prior art in order to the articles for use sterilization difficulty that improves patient temperature, have the bigger potential safety hazard and the problem of poor temperature uniformity.

In order to address the above problem, the technical solution used in the present invention is: this operation table comprises supporting seat, be installed on the bed board and the mattress that is arranged on the bed board of supporting seat upper end, be embedded with in the described mattress and be the double flexible pipe that helix shape is provided with of gradually opening, the water inlet of described flexible pipe is connected with water tank by water inlet pipe, the outlet of described flexible pipe is communicated with described water tank by return pipe, described return pipe is provided with water pump, the bottom of described water tank is provided with the heater by temperature controller control, be connected with relay between described heater and the described temperature controller, described water tank, described water inlet pipe, be provided with a plurality of temperature sensors in the circulation canal that described flexible pipe and described return pipe constitute, described water inlet pipe is provided with electromagnetic valve, described temperature sensor, described electromagnetic valve, described relay and described water pump are electrically connected with described temperature controller respectively; The top of described water tank is provided with air bleeding valve, is provided with the liquid level sensor that is electrically connected with described temperature controller in the described water tank, and described water tank is connected with the feed pipe of band water compensating valve.

In the technical scheme of above-mentioned operation table, technical scheme can also be more specifically: the skin of described mattress is a leather, is provided with double-deck foam-rubber cushion in the described mattress, and described flexible pipe places between the double-deck foam-rubber cushion; Described water inlet pipe, described flexible pipe and described return pipe are silica gel tube.

Further, on described water inlet pipe and described return pipe, be provided with the switch valve of band snap joint.

Further, described a plurality of temperature sensor is arranged at the water inlet and the outlet of the outlet of described water tank, described flexible pipe respectively.

Further, described water tank, described heater and described water pump are positioned in the equipment room, and described water inlet pipe and described return pipe underwent operative chamber tower crane are connected to described flexible pipe.

Owing to adopted technique scheme, the present invention compared with prior art has following beneficial effect:

1, in mattress, buries flexible pipe feeding hot water underground and heat mattress, directly give patient's additional heat, and come control water temperature, thereby effectively control the mattress temperature by temperature controller, heater and a plurality of temperature sensor; Electromagnetic valve and relay are set, can cross when hanging down in temperature and charge into hot water, mattress is used under keeping warm mode, stop heating when temperature is too high automatically, avoid scalding the patient, the security performance height;

2, flexible pipe is the double helix shape of gradually opening and is arranged in the mattress, mattress is heated evenly, and is beneficial to the prolongation temperature retention time;

3, the leather bed surface is easy to sterilization, can prevent germ reproduction, can effectively avoid cross infection; Foam-rubber cushion softness, conduct heat fast, good heat insulating can be brought good comfort to the patient; Silica gel tube is harmless nonpoisonous and tasteless, fabulous resistance to elevated temperatures is arranged, the anti-fight anti tear, it is little to have splendid resilience and permanent deformation, have excellent electric insulation performance, fungicidal properties simultaneously, can effectively ensure the sanitary condition and the service life of water inlet pipe, flexible pipe and return pipe;

4, the switch valve of band snap joint is set in the junction of water inlet pipe, outlet pipe and mattress inner flexible tube, can makes a cover hot-water supply device be used for different operation tables, and realize replacing fast;

5, temperature sensor is set in order to monitoring heating water temperature at the outlet of water tank, temperature sensor is set in order to monitoring with calculate the actual temperature of mattress at the water inlet of flexible pipe and outlet, so that accurately control is temperature required as required;

6, water tank, heater and water pump etc. place in the equipment room, can avoid these devices to take the operating room space and influence the operating room environment temperature; Water inlet pipe and return pipe are connected to operation table through tower crane, are beneficial to keep the succinct of operating room environment.
