Description

Medical central negative pressure attracts pipe-line system

Technical field

This utility model relates to a kind of medical system, refers to that especially the medical central negative pressure that reduces cost after a kind of the improvement attracts pipe-line system.

Background technology

Popularization gradually along with central oxygen supply system, in order to improve the medical treatment level of hospital, patient in the hospital is provided the nursing level of better effects if, many hospitals all bring into use vacuum suction system, traditional vacuum suction system normally adopts independently mechanical attraction equipment to realize, these independently mechanical attraction equipment not only can take big medical care space, and break down easily, therefore be not easy to frequent use, influenced the medical treatment level of hospital, at present, the central negative pressure attraction system has replaced traditional machinery and has attracted equipment, with respect to these traditional mechanical attraction systems, the central negative pressure attraction system exists has many uses, simple to operate, give treatment to advantage efficiently, be mainly used in absorption expectorant, blood, the treatment link of dirt in pus and other bodies, and can effectively improve ward environment, alleviated medical personnel's physical work, and attraction is successively also available at any time, has improved curative effect greatly.The central negative pressure attraction system generally includes central negative pressure attraction station and the vacuum suction pipeline formation that is used to produce negative pressure, central negative pressure attracts the station to be made up of vacuum pump, vacuum tank, gas-liquid separator, valve, electrical control cubicles and electromagnetic valve etc., electrical control cubicles and starting of solenoid control vacuum pump and shutdown, negative pressure in the vacuum tank is remained in the suitable scope, usually vacuum pump autostop when negative pressure reaches 0.07Mpa in the vacuum tank; When negative pressure uses 0.03Mpa in the vacuum tank, vacuum pump starts voluntarily, the pressure bound of the automatic open and close of this control pump can be adjusted by hospital's requirement, the startup of vacuum pump is with close can automatically also can be manual, thereby keep suitable negative pressure, the vacuum suction pipeline comprises pipeline and adnexa, central negative pressure attracts the negative pressure at station to be transported to the boxlike terminal through the vacuum suction pipeline, array terminal or tower crane end, be connected with attracting terminal, usually attract terminal by self-styled quick plug of plug-in and boxlike terminal, array terminal or tower crane terminal fast sealing connect, at hospital operating room, rescue room, the end in therapeutic room and each ward produces suction, thereby for medical patient provides the medical care service, especially be used in operating room, ICU and rescue room, not only improve the grade of hospital, the more important thing is and to improve medical level and efficient, have bigger use value.

The central negative pressure attraction system is when occurring, people consider from the angle of safety, be to adopt the comparatively firm metallic conduit of pipeline always, thicker main line adopts thick coating steel pipe, house steward in the ward then adopts thinner galvanized pipe, arm adopts thinner and flexible copper pipe in the ward, central negative pressure attraction system is afterwards continued to use this design always, because the acquisition cost of these metal tubes is higher, and it is bigger to the most important thing is that pipeline connects difficulty of construction, make whole system cost cost high, higher cost has hindered this central negative pressure attraction system in the extensive installation of hospital with popularize, be unfavorable for patient is implemented multiple effective treatment, have only a handful of big-and-middle-sized hospital to use this central negative pressure attraction system at present, the cost that reduces the central negative pressure attraction system is popularized it in medical institutions, thereby reduces the patient medical cost, improves social welfare and just seems particularly important.

The utility model content

Technical purpose of the present utility model is in order to provide a kind of negative pressure gas pipeline to adopt the medical central negative pressure of macromolecular material to attract pipe-line system, to attract pipe-line system thereby reduce the medical central negative pressure of installing and using cost greatly.

For achieving the above object, the medical central negative pressure of this utility model attracts pipe-line system and includes the central negative pressure attraction station of power supply, attract terminal to constitute medical central negative pressure attraction system together, central negative pressure attracts the station by vacuum pump, vacuum tank, valve, check valve, pressure is controlled electric control gear automatically and is constituted, power supply is controlled electric control gear automatically with vacuum pump and pressure and is connected, pressure is controlled electric control gear automatically and is connected with vacuum tank with vacuum pump, the air entry of vacuum pump is connected with vacuum tank by behind the check valve, vacuum pump is connected with valve seal, the vacuum suction pipeline comprises main line, divide pipeline and bye-pass, the main line and the vacuum tank of negative pressure transportation pipeline are tightly connected, branch pipeline and main line conducting also is distributed in the medical care ward, bye-pass one end is connected with dividing pipeline, the port distribution of the other end is used for being connected with attracting terminal before the sick bed in medical care ward, the main line of this vacuum suction pipeline, divide pipeline and bye-pass all to adopt nontoxic plastic conduit, adopt threaded end (TE) to be tightly connected between this main line and the vacuum tank, adopt the glue mouth of pipe to be tightly connected between main line and the branch pipeline, the two-port place of main line and branch pipeline is neat mouthful, divide and adopt threaded end (TE) to be tightly connected between pipeline and the bye-pass, divide and adopt threaded end (TE) to be tightly connected between pipeline and the bye-pass, be generally and reduce cost, can directly be provided with through hole on this minute pipeline, directly be provided with female thread in this through hole, bye-pass by one connect tube head with this minute pipeline be connected, one end and the bye-pass of this connection tube head are tightly connected, the other end is provided with external screw thread, and the interior set female thread of through hole directly is tightly connected on this external screw thread and the branch pipeline.

Above-mentioned main line and branch pipeline are RPVC (PVC-U pipe), and described bye-pass adopts polyurethane tube (PU pipe).

Beneficial effect: because the medical central negative pressure of this utility model attracts the negative pressure transportation pipeline of pipe-line system to adopt comparatively cheap plastic cement pipe, particularly adopted nontoxic RPVC (PVC-U pipe) as main line and branch pipeline, and adopt polyurethane tube (PU pipe) as bye-pass, therefore not only can significantly lower the cost that this medical central negative pressure attracts the used pipeline material of pipe-line system, and because the pipeline of plastic material is easy for installation, can reduce the human cost of installation effectively, and the maintenance cost in later stage, usually be 1000 meters calculating with pipeline length, the cost of its saving surpasses more than 50%, and pipeline to grow up to this saving more many more, therefore be convenient to this medical central negative pressure and attract the popularization of pipe-line system in medical institutions, the final cost that reduces society's medical treatment and rescue, improve people's medibank, in addition, the negative pressure transportation pipeline of employing polrvinyl chloride and polyurethane tube not only can not produce rust staining and cause the pipeline internal contamination, and the life-span also can double, the structure of circuit is convenient to repacking, it is also comparatively convenient to safeguard, the final actual cost of using that reduces greatly.

For ease of explanation detailed content and the technology relevant, below describe with regard to conjunction with figs. now with this utility model.
