Abstract
The utility model relates to a medical appliance, in particular to a pressure transducer used for a pressurized rinser. The pressure transducer comprises a main body connected with a pressurizer, and a sensor is connected at the portat one end of the main body; a connector is connected at the other end of the main body, and a water inlet and a water outlet are arranged on the connector; the connector is connected with a water storage bottle. The pressure transducer mainly provides a pressure transducer which is suitable for disposable use and can prevent the cross infection germina; the pressure transducer solves the technical problem existing in the prior art that the cleaning is inconvenient, and the cross infection is easy to occur.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of pressure converter that is used on the pressure flush device.
Background technology
During medical treatment was clinical, various interventional therapy operations such as stomach, intestinal mirror and endoscope were extensively popularized, and the doctor can intuitively see the position of being checked by above-mentioned endoscope.In actual mechanical process, because the position of the required inspection of patient often needs cleaning, so all be provided with the pressure flush device in the operating theater instruments such as existing endoscope.As Chinese patent: " the pressure flush device (CN2745525Y) that is used for gastrointestinal endoscopy ", it discloses a kind of prelum, comprise and add compression pump, water-storage pot, its add Pressure gauge that pressure-regulating valve one end installed on the compression pump is provided with by connecting duct be connected with the water-storage pot bottleneck again after check valve is connected, suction pipe passes bottle cap sealing and joins, its suction pipe one end inserts in the water-storage pot, and be provided with outlet in a side of the suction pipe other end, effluent switch is installed on the top of suction pipe, outlet and conduit join, and the other end of irrigating catheter is installed nozzle.This irrigator flow velocity is adjustable, easy to operate, high safety.But the inconvenient cleaning and sterilizing of this irrigator is easy to generate cross infection, must regulate by the pressure in the test water-storage pot.
Summary of the invention
This utility model has mainly provided and has been fit to disposable use, can prevent the pressure converter of cross infection pathogenic bacteria; Solve existing in prior technology and be inconvenient to clean, be easy to generate the technical problem of cross infection.
This utility model also provides a kind of simultaneously can carry out regulating and controlling pressure, the pressure converter that cost is low by testing the external air pressure that contacts water with human body; Solve the pressure that must directly test the water that directly contacts with the people that exists in the prior art and regulate, easily the technical problem of bacteria infection.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of disposable pressure transducer, comprise the main body that links to each other with prelum, and an end interface place of described main body is connected with pick off; The other end of described main body is connected with joint, and described joint is provided with water inlet and outlet; Described joint and water-storage pot join.Between prelum and water-storage pot pressure converter is set, pressure converter is a disposable product, and cost is low.Can directly abandon after the use, reduce the probability of cross infection, no longer need the pressurization instrument is carried out disinfection, make work simpler.By on pressure converter, connecting pick off, indirect test the pressure in the water-storage pot, come controlled pressure to change according to the demonstration of pick off.
As preferably, form airtight cavity between described main body and the joint, the seam that connects pick off in described main body is provided with adapter; Be provided with flexible pipe between described joint and described adapter, brinish pressure is varied to linear relationship in the change in volume of described flexible pipe and the flexible pipe.Medical prelum enters certain afterburning saline in the flexible pipe from water inlet, enter human body from the joint water outlet, volume increases flexible pipe with the increase of saline reinforcing, this flexible pipe is a silicone rubber tube, silicone rubber is made with special material, and brinish pressure changes with the change in volume of silicone rubber tube linear.The main body left end connects pick off, goes out according to sensor measurement that the variation of air changes into prelum water outlet place salt water pressure in the main body.In the main cavity and outside seal, relative sealing between the interior air of special soft silicon rubber tube and main cavity.The pressure of test is the air pressure from airtight cavity, so directly do not contact with wash water, makes wash water directly to enter the flushing position by joint, has prevented multiplicity of infection midway.
As preferably, between described flexible pipe and joint, be provided with fixed cover; The other end and adapter joint at described flexible pipe are provided with fixed cover.Fixed cover is set strengthens sealing effectiveness, make pick off sensitiveer, data are more accurate.
As preferably, described joint is the three way cock, and described flexible pipe is a silicon rubber hose.Three way cock's a end connects water inlet, and an end connects outlet, and the other end connects flexible pipe.
As preferably, described main body is made by macromolecular material.The employing macromolecular material is made, and cost is low, is fit to disposable medical apparatus and instruments.
Therefore, disposable pressure transducer of the present utility model has following advantage: 1, between prelum and water-storage pot, pressure converter is set, not only can regulates and control water inlet and discharge pressure easily, and disposable use, reduced the disinfectant requirement; 2, in the main body of pressure converter, be provided with airtight cavity, silicon rubber hose is set in cavity, adjusts pressure, make pick off directly directly not contact with saline with flushing by the variation of air pressure in the test cavity, reduce the chance of cross infection, safety is better; 3, disposable utensil, cost is low, and easy to use.
Description of drawings:
Fig. 1 is the sketch map of disposable pressure transducer of the present utility model.
The concrete thing mode of implementing:
Below by embodiment, and in conjunction with the accompanying drawings, the technical scheme of utility model is described in further detail.
Embodiment:
As shown in Figure 1, the disposable pressure transducer, comprise the main body 6 that links to each other with pick off on the prelum, the other end of main body 6 connects three way cock 1, three way cock's 1 clockwise direction is respectively equipped with water inlet 2, outlet 12 and main body interface 13 form an airtight cavity between main body 6 and the three way cock 1.Be provided with adapter 5 at main body and the pick off end that joins, between three way cock 1 main body interface 13 and adapter 5, be provided with special soft silicon rubber hose 4, medical prelum enters certain afterburning saline in the flexible pipe 4 from water inlet 2, enter human body from joint outlet 12, volume increases flexible pipe with the increase of saline reinforcing, this flexible pipe is a silicone rubber tube, and silicone rubber is made with special material, and brinish pressure changes with the change in volume of silicone rubber tube linear.Main body 6 left ends connect pick off, and the variation that goes out air in the main body cavity according to sensor measurement changes into prelum water outlet place salt water pressure.All be socketed with fixed cover 3 and fixed cover 7 at the two ends of flexible pipe 4, be used for sealing.
Specific embodiment described herein only is that design of the present utility model is illustrated.This utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
