Definitions

  • Corrugated tube type medical pump The utility model relates to a corrugated tube type medical pump, which is especially suitable for use at the emergency site.
  • sputum, pus, blood, and amniotic fluid are often attracted and washed.
  • sputum, pus, and blood have a certain degree of sputum
  • most of the membrane-type electromechanical aspirators are currently used, and the suction is required to be controlled at any time during the suction, and intermittent Intermittent operation makes the electromechanical control mechanism complicated, cumbersome to operate, bulky, and costly, and it is difficult to popularize it to the emergency site.
  • the purpose of the utility model is to provide a medical pump which is compact, lightweight, hygienic and inexpensive, and can be used once.
  • the corrugated tube medical pump of the utility model is composed of an elastic frame and a corrugated pump barrel with inlet and outlet tubes.
  • the elastic frame is an 8-shaped or U-shaped upper opening.
  • the corrugated pump barrel has two inlet and outlet tubes. The ends are respectively clamped at two ends of the elastic frame. Springs can be added to the elastic frame to increase elasticity.
  • the elastic frame is manually stretched or the foot is compressed to change the volume of the corrugated pump barrel to produce a pressure difference.
  • the corrugated pump barrel has the characteristics of easy axial deformation and large radial pressure resistance, so it can form a pump barrel with high efficiency, no leakage and good charge and suction performance.
  • the elastic frame is a single component and easy to manufacture.
  • the medical pump of the utility model has the advantages of simple structure, low cost, convenient and quick assembly and disassembly.
  • FIG. 1 shows a first embodiment of the present invention, which is a manual attractor.
  • FIG. 2 shows a second embodiment of the present invention, which is a foot-suction and suction pump.
  • the manual suction device shown in FIG. 1 is composed of a corrugated pump cylinder 1, an "8" elastic frame with an upper opening, an inlet pipe 3 with a check valve, an outlet pipe 4, and a liquid bag 5.
  • the lower part of the elastic frame is for increasing elasticity.
  • a U-shaped leaf spring 6 can be added, and the ends of the inlet and outlet pipes of the corrugated pump barrel are separately clamped on the elastic frame On both ends, the inlet and outlet pipes can be equipped with film tube type or knife chip type check valves.
  • the front section of the inlet tube that contacts the human body may be a soft tube, and the rear section connected to the corrugated pump barrel is a hard tube, which will not hurt the human body and control the suction position.
  • the foot charging pump of Fig. 2 is composed of a corrugated pump barrel 9 and a U-shaped elastic frame 11.
  • the upper end of the pump barrel is provided with an inlet pipe 7 and an outlet pipe 8 with a check valve.
  • a coil spring 12 can be added on both sides of the elastic frame to increase the elastic force.
  • a one-time transition suction bottle with a built-in air cushion can be connected to the front end of the inlet pipe.
  • the pedal pump has a large power, can be used for charging and suction, is convenient to switch, and has many uses, for example, it can be used in a vacuum stretcher and a pneumatic hemostatic suit for emergency.
  • the corrugated pump cylinder of the utility model can be manufactured by a blow molding process, has a low cost, is very healthy, and can be used once.
  • the elastic frame can be made of steel sheet or engineering plastic at one time, and can be used repeatedly. After testing, the suction can reach 0.08 MPa, and the weight is only 60-200 grams, which is especially suitable for on-site first aid and home beds. At present, people attach great importance to the problems of first aid and cross infection, so the utility model has broad application prospects.

Abstract

L'invention concerne une pompe de type tuyau ondulé à usage médical se prêtant surtout à une utilisation en cas d'urgence. La pompe est constituée d'un élément élastique présentant une ouverture supérieure et une forme en 8 ou U et d'un tuyau ondulé doté d'un tube d'entrée et de sortie. Les extrémités présentant une entrée et une sortie se trouvent entre deux extrémités de l'élément élastique. On peut obtenir une pression différentielle en poussant ou appuyant sur le tuyau ondulé en actionnant l'élément élastique avec la main ou le pied. La pompe présente des propriétés efficaces de pompage et d'évacuation, peut être pliée, se fabrique à un faible coût et est jetable après l'emploi.
