Description
Technical field
This utility model relates to a kind of controllable type and filters suction pump, belongs to medical sucting apparatus field.
Background technology
Suction pump is an indispensable apparatus in the surgical operation, and in surgical procedures, suction pump is not only in time absorbed the blood that oozes out in the art, keeps surgical field of view clean, clear, the harmful gas that produces in the time of also can inhaling electric knife incised tissue in the art.But traditional suction pump is a straight rubber tube or the metal tube that has side opening, often, blood clot, GUSUIPIAN, slough cause suction pump to stop up in the art because of being inhaled into, influence the operation process, excessive or too small because of suction pump pressure in addition, and the situation puzzlement surgeon who influences the process of operation and cause the damage of tissue.Cause the omentum majus damage and cause suction pump to block as having in department of general surgery's operation because of omentum majus is inhaled into; Thoracic surgery also has accidentally tissues such as fibrous membrane to be sucked because of suction is excessive and causes the fibrous membrane breakage; The Orthopeadic Surgery spinal operation also has because of suction is excessive and causes spinal dura mater to break, spinal cord, nerve root injury.The processing of need stopping of above-mentioned situation operation process takes place, the obturator in the suction pump is taken out, the influence operation is carried out smoothly, so control suction pump pressure and filter and attract liquid to keep the unimpeded very important function that plays smoothly performing the operation of suction pump.The requirement that can not satisfy the surgical operation accurate operation in view of traditional suction pump reaches in order to remove surgical puzzlement, make suction pump can really bring into play due effect, must filter suction pump as surgical " good assistant " by a kind of controllable type of design, to adapt to the development of surgical technic and treatment theory for this reason.
Summary of the invention
The purpose of this utility model is to design and a kind ofly can overcomes above-mentioned disadvantage, and simple in structure, can be anti-blocking and make things convenient for the controllable type of controlled pressure to filter suction pump.
This utility model in order to achieve the above object, provide a kind of controllable type to filter suction pump, constitute by suction catheter (2), side opening (3) and outlet (9), it is characterized in that drainage screen (8) is fixed on filter tube (1) one end, the other end of filter tube is screwed on the suction catheter, sliding tray (6) is installed on the tube wall of suction catheter, stud with wiper (4) on the sliding tray, gauge tap (5) is fixed on the wiper, end at sliding tray has side opening (3) to be communicated with the suction catheter inner chamber, and the suction catheter upper end is for outlet (9) and connect the negative pressure interface.
This utility model controllable type filters suction pump, and described suction catheter is an integrative-structure, and available solid metal bar is processed into a kind of hollow cavity of reducing, as shown in Figure 1.Suction catheter also can be processed into the suction catheter of same internal diameter with the thicker metal tube of tube wall, as shown in Figure 5.End at suction catheter (2) has been attacked female thread, sliding tray (6) is installed on the tube wall of suction catheter and is drilled with side opening, and the other end of suction catheter is an outlet, and the outlet outer wall has 1～3 ring fin.It is when guaranteeing to connect sebific duct that the ring fin is set, and makes both adhesion-tights, avoids sebific duct to come off in use.
This utility model controllable type filters suction pump, and described filter tube (1) one end is provided with screw thread (7), and screw thread is screwed on the suction catheter, and the filter tube other end is fixed with drainage screen (8).Be provided with screw thread (7) at filter tube (1) one end, can utilize screw thread easily filter tube to be screwed on suction catheter, help dismounting and change or cleaning and sterilizing.At the fixing drainage screen of the filter tube other end, drainage screen is that flat net sheet directly is welded on the filter tube, or threaded short net post is screwed on the filter tube.Drainage screen is set not only can prevents obstruction suction catheters such as sludged blood, broken bone end, can also prevent the stretch injury of over-drastic attraction tissue.
This utility model controllable type filters suction pump, and sliding tray (6) is installed on the suction catheter.The mode of installing can directly be welded in sliding tray and attract on the tube wall, a side opening (3) is arranged through to the suction catheter inner chamber on sliding tray and attraction tube wall, and the suction catheter upper end is for outlet (9) and connect the negative pressure interface.Stud with wiper (4) on the sliding tray, gauge tap (5) is fixed on the wiper, promotes gauge tap, and wiper can slide up and down in sliding tray, and when wiper slides into the lower end of sliding tray, side opening is closed fully.The size that the size of utilizing gauge tap to regulate wiper switching side opening is regulated suction pump suction.When side opening place buttoned-up status, the suction maximum that filter tube is subjected to is from the attraction flow quantity maximum of outlet discharge; Otherwise, during the complete open state in side opening place, the suction minimum that filter tube is subjected to, the flow minimum that attracts liquid to discharge from outlet, so user can to regulate suction pump pressure, satisfy the requirement of different operative sites according to operation needs regulation control switch at any time.Change a simple saying, if negative pressure is crossed when strong, can open side opening, suction pump pressure just diminishes.
The utlity model has following advantage:
1, this utility model suction pump is simple in structure, and is easy to make, and cost of manufacture is relatively low.
2, this utility model suction pump is owing to the end at filter tube is equipped with drainage screen (8), can stop sludged blood, broken bone end to suck the suction catheter that causes and stop up, the operation process cleaning obturator that need not to stop, not only saved the time, also provide essential condition for patient safety undergos surgery smoothly for operation.
3, this utility model suction pump has side opening at suction catheter tube wall and the design of sliding tray one end, wiper and gauge tap have been installed in sliding tray, these structures can make the pressure of suction pump be effectively controlled, promote gauge tap and just can regulate suction pump pressure easily, satisfy different operative sites to the pressure requirement, can also prevent the stretch injury of over-drastic attraction tissue.
