Abstract
The utility model provides an automatic saccule expansion device for gynaecological hydrotubation. The output of an air injection pump is connected with a tee, one end of the tee is connected with a pressure sensor, the other end of the tee is connected with an air injection opening of a double lumen tube saccule, and a motor of the air injection pump is connected with a control circuit. The structural design of the utility model is characterized in that the air injection pump is composed of the motor, a screw rod, a piston and an air cylinder, wherein the output end of an air cylinder is connected with a pressure sensor and the air injection opening of the double lumen tube saccule, and the motor of the air pump is controlled by a control circuit according to the press value of the feed back of the pressure sensor. The product of the utility model has the advantages as follows: through the recombination and the design to the product, the automatic air injection to the double lumen tube saccule is achieved in gynaecological hydrotubation, and the safety and the effectiveness during the process are improved.
Description
Technical field
The utility model is a kind of swollen expansion device of automatic sacculus that is used for the logical liquid art of gynaecology, belongs to the structure and the design field of product.It relates to structural improvement of existing product and technical raising.
Background technique
At present the logical liquid art field of gynaecology is to the expansion of the double lumen tube shutoff sacculus that enters uterine cavity, be to take 10 milliliters of injector for medical purpose to inject to the gas injection of double lumen tube sacculus suction port by manual, the volume that reaches expansion has the operator to grasp by rule of thumb fully, but because of human body difference, be easy to overshoot and bring misery, or underexpansion causes the logical liquid art failure of back to the patient.
Summary of the invention
The objective of the invention is the deficiency that exists at prior art and the swollen expansion device of new type auto sacculus that provides is provided, it is on prior art, product has been carried out combination and design again, realized in the logical liquid art of gynaecology, to the automatic gas injection of double lumen tube sacculus, improved the Security and the validity of this process.
The purpose of this utility model is implemented by following measure:
The swollen expansion device of the automatic sacculus of this kind, the output of gas injection pump connects threeway, and an end of threeway connects pressure transducer, and the other end of threeway connects double lumen tube sacculus gas injection port, and the gas injection pump motor connects control circuit.Its structural design features is, the gas injection pump is made of motor, screw mandrel, piston, cylinder, the output terminal of cylinder is connected with the sacculus gas injection port of pressure transducer and double lumen tube, and the control of the motor of air pump is controlled according to the force value size of pressure transducer feedback by control circuit.
Description of drawings
Fig. 1 is the overall structure schematic representation of the utility model product
Embodiment
Below with reference to drawings and Examples the utility model product is described in further detail:
Shown in accompanying drawing 1, the swollen expansion device of the automatic sacculus of this kind, the output of gas injection pump (1) connects threeway (2), one end of threeway (2) connects pressure transducer (3), the other end of threeway (2) connects double lumen tube sacculus gas injection port (4), reducing motor (5) connects control circuit (6), and its structure characteristic is: the gas injection pump is made of screw mandrel (7), piston (8), cylinder (9).During use, control circuit (6) powers up for reducing motor (5), screw mandrel (7) rotation promotes piston (8) and advances in cylinder (9), pressurized air by threeway (2) to double lumen tube sacculus gas injection port (4) gas injection, make the sacculus of double lumen tube begin to expand, and by the variation in pressure in pressure transducer (3) the detection sacculus, control circuit (6) is analyzed the variation in pressure in the gas replenishment process, identify the opportunity that stops gas injection according to the double lumen tube inflated to expand transition point and the variation in pressure when being inflated to sacculus and touching uterine wall, closing control circuit (6) is to the output of speed motor (5).
The advantage of the utility model product is by product having been carried out combination and design again, having realized to the automatic gas injection of double lumen tube sacculus, having improved security and the validity of this process in the logical liquid art of gynaecology.
Claims (1)
