Abstract
The utility model relates to a 'self-control electric suction apparatus for medicine analgesia', which is an apparatus for a surgical operation of a medicine clinic. The utility model is additionally provided with an operational amplifier circuit control device which is composed of a plurality of electronic apparatuses on the basis of the existing ' electric suction apparatus '. Thus, the defect that the existing ' electric suction apparatus ' is easy to disperse the operation energy of an operator and increases the labor intensity of the operator is overcome, so that the aim of the sensitive and convenient operation of the operator is achieved; simultaneously, the utility model reduces the responsiveness of nerves of patients with electricity for people on operation, and performs a tranquilizing and an analgesia effects.
Description
This utility model is for apparatus practical in the clinical medicine surgical operation.It is relevant with existing " riding " formula switch " electric suction apparatus ".
People know: in the nervous and meticulous surgical operation of long time such as the cranium brain in the clinical medicine, neck, breast abdominal part, employing be " ride " formula switch " electric suction apparatus ", unavoidable patient's energy and increase patient's the intensity of standing of disperseing in the art; The phenomenon that " opening " " stops " " electric suction apparatus " incoordination also usually appears.
This invention of " medical analgesia auto-controlled electric suction pump " is to overcome the deficiency of existing " electric suction apparatus " exactly.Reach in the art to the charged sedation and analgesia of operation receiveing person and reach the purpose of " driving " " stopping " electric suction apparatus by the required automatic control of patient.
Description of drawings
The accompanying drawing automatic control circuit schematic diagram of representing to ease pain.Critical piece comprises: electrode attracts head (1), folder formula electrode (2), amplification control circuit (3) is an existing electronic technology main in the frame of broken lines, linearity amplifier piece 5G24, electronic relay J, audion BG1, BG2 etc., amplification control circuit (3) output control load is the dynamic/static contact (4) of electronic relay, motor (5), variable resistance (6).
Implement and use-case:
On existing electric suction apparatus basis, (copper) metal that will conduct electricity attracts head to connect a lead becomes electrode attraction head (1), with the other end of this lead along suction catheter to the electric suction apparatus main part (motor, amplification control circuit etc.), with input terminal among the linear amplifier piece 5G24 in the amplification control circuit (3) 3. (or 2.) be connected, 6. the outfan of 5G24 is connected with the base stage Sr point of audion.Colelctor electrode by BG1, BG2 is to the relay J coil.Its output control load (being relay J) dynamic/static contact (4) is series on the power firestreak of motor (5).Other connects negative 2 to 10 volts dc source and places on operation receiveing person's body (non-field of operation) by variable resistance (6) to the copper folder formula electrode (2) with lead, add the static of about 500 microamperes of low pressure to body, make operation receiveing person's stress the descending of nerve to reach the effect of sedation and analgesia.
After connecting according to foregoing circuit, in art,, all can feel the upward faint electrical information of organism physiology not being had influence as long as electrode is attracted head (1) contact operation receiveing person's an arbitrary position (mainly referring to field of operation liquid).This little electrical information is transported to the control load relay J after amplifying by amplification control circuit (3), and closed its dynamic/static contact (4) reaches the purpose that motor (5) power supply is connected in control.Make it suction pump work.Otherwise, when attracting head (1), electrode leaves operation receiveing person's body (mainly referring to field of operation liquid), and then relay dynamic/static contact (4) is open, reaches the purpose of automatic cut-out motor (5) power supply.Making it suction pump quits work.
In the analgesia automatic control circuit of above-mentioned " self-control electric suction apparatus for medicine analgesia ", only after the basis of existing " electric suction apparatus " adds in a small amount and at a low price electronic equipment, reached the patient use easy to operate, the purpose of giving simultaneously the charged sedation and analgesia of operation receiveing person.
Claims (3)
1, medical electric suction apparatus, particularly medical analgesia auto-controlled electric suction pump is made up of motor, attraction head, suction catheter etc., it is characterized in that a kind of electrode that attracts to be connected to lead on the head at conducting metal attracts head (1); Electrode attracts head (1) to be connected with the input terminal of amplification control circuit (3) by lead (other end).
2,, it is characterized in that adding low-tension supply and place on operation receiveing person's body (non-field of operation) by variable resistance (6), folder formula electrode (2) according to the described medical analgesia auto-controlled electric suction pump of claim 1.
3, according to the described medical analgesia auto-controlled electric suction pump of claim 1, it is characterized in that the dynamic/static contact (4) of the output control load (relay J) of amplification control circuit (3) is series at respectively on the power firestreak of motor (5).
