Abstract
The utility model discloses a negative pressure aspirator which comprises a suction tube. A pressure control system is arranged in the suction tube and comprises a pressure sensor, a programmable logic controller (PLC) and a motor which are sequentially connected, wherein the pressure sensor is arranged on the inner side of the suction tube wall, and the PLC and the motor are arranged outside the suction tube. The negative pressure aspirator overcomes the defect of uncontrollable pressure of the existing negative pressure aspirators.
Description
Technical field
This utility model belongs to medical sucting apparatus field, is specifically related to a kind of novel negative pressure suction pump.
Background technology
Suction pump is the medical apparatus that the doctor uses always, and it not only is used for absorbing, and operation is hemorrhage, flushing liquor etc., also is usually used in the drain of postoperative exudate and purulent secretion etc., thereby promotes tissue better to repair and the recovery from illness of disease.The too small meeting of suction pressure causes inadequate drainage, hematocele and hydrops etc., and suction pressure is excessive then can to cause tissue injury, flap necrosis etc., serious harm patient's health.Its pressure of common in the market suction pump is unadjustable, can not regulate the pressure size according to actual needs, not only brings bigger pressure to medical and nursing work, also usually brings irreversible damage to the patient.
The utility model content
The technical problem that this utility model will solve is to the uncontrollable shortcoming of existing vacuum extractor pressure, and a kind of novel negative pressure suction pump of adjustable pressure is provided.
In order to solve the problems of the technologies described above, this utility model provides following technical scheme:
A kind of novel negative pressure suction pump comprises suction catheter, wherein, is provided with control pressurer system, and control pressurer system comprises pressure transducer, PLC, the motor that connects successively, and pressure transducer is positioned at the tube wall inboard of suction catheter, and PLC, motor are positioned at outside the suction catheter.
Adopt a kind of novel negative pressure suction pump of this utility model technical scheme, owing to be provided with control pressurer system, pressure transducer is positioned at the force value of the tube wall inboard of suction catheter in order to the The real time measure suction catheter; And send the real-time pressure value to PLC; PLC compares itself and the force value that configures in advance, thereby control is regulated the force value in the suction catheter through motor, makes that finally the real-time pressure in the suction catheter is consistent with the force value that configures in advance; Thereby make the sucting strength accurate and adjustable; Help the early stage recovery from illness of body and tissue, avoided unnecessary damage, and simple to operate.
Description of drawings
Below in conjunction with accompanying drawing and embodiment this utility model technical scheme is further specified:
Fig. 1 is the sketch map of a kind of novel negative pressure suction pump of this utility model embodiment.
The specific embodiment
As shown in Figure 1; A kind of novel negative pressure suction pump of this utility model comprises suction catheter 1, wherein; Be provided with control pressurer system; Control pressurer system comprises pressure transducer 2, PLC3, the motor 4 that connects successively, and pressure transducer 2 is positioned at the tube wall inboard of suction catheter 1, and PLC3, motor 4 are positioned at outside the suction catheter 1.
In the practical implementation process, it is CP1L-M40DT-D that PLC3 adopts model, and multiple force value wherein is set.When using; The acquiescence force value at first is set on PLC3, when suction catheter 1 with after intravital various drainage tubes are connected, be positioned at the real-time pressure that the inboard pressure transducer 2 of tube wall is experienced suction catheter 1; The real-time pressure value is fed back to PLC3; PLC3 controls real-time pressure value and the contrast of acquiescence force value thus in motor 4 and regulates the force value in the suction catheter 1, finally makes the real-time pressure value consistent with the acquiescence force value.
For a person skilled in the art; Under the prerequisite that does not break away from this utility model structure; Can also make some distortion and improvement, these also should be regarded as the protection domain of this utility model, and these can not influence effect and practical applicability that this utility model is implemented.
