Abstract
A buffer device for a negative-pressure suction device is provided with a buffer container, wherein an air inlet tube connected with a suction head of the negative-pressure suction device and a suction tube connected with a negative-pressure suction device body are arranged on the buffer container; the buffer container is filled with filler capable of absorbing water and adsorbing protein; the air inlet tube is connected with the suction head through a quick coupling; a flow control switch is arranged on the air inlet tube; a suction flow meter is arranged on the air inlet tube between the flow control switch and the suction head. According to the buffer device for the negative-pressure suction device, the buffer container is arranged at the suction head, so that negative pressure can be buffered, and the blockage caused by that fact that a liquid or solid protein is sucked into the negative-pressure suction device body can be prevented; the filler is added to the buffer container and can absorb water or adsorb protein without influencing suction force; the buffer container is separable and can be replaced, cleaned and disinfected regularly, and accordingly, high cost of system maintenance caused by negative-pressure blockage is avoided.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly to the buffer unit of a kind of vacuum extractor.
Background technology
Suction pump is for absorbing the content in hands intraoperative hemorrhage, exudate, pus, thoracic organ, makes operation clear, reduces opportunities for contamination.The principle of suction pump is the negative pressure state by manufacturing sucking head, and the material outside sucking head will be extruded to sucking head, thus complete the effect of " attraction " by such atmospheric pressure.
The vacuum effect of existing suction pump is to be provided by HC negative pressure room, and once suction pump is because of the excessive or careless suction liquid of vacuum suction and solid protein, is difficult to sucking-off and easily causes blocking；Vacuum suction union joint cleans difficulty and changes union joint costly；Vacuum suction connector position once suction weakens, and does not just reach good attraction effect, attracts clean, and once central negative pressure system because of blocking or is not cleaned out, and causes the damage of whole central negative pressure system, and then maintenance difficult and costly.
Summary of the invention
The technical problem to be solved is for the deficiencies in the prior art, it is provided that a kind of reasonable in design, the buffer unit of vacuum extractor easy to use.
The technical problem to be solved is to be realized by following technical scheme, the present invention is the buffer unit of a kind of vacuum extractor, it is characterized in, it is provided with buffer container, the side of buffer container is provided with the air inlet pipe that the sucking head with vacuum extractor connects, the opposite side of buffer container be provided with connect with vacuum extractor main body suction catheter, it is provided with in buffer container and can absorb water and the implant of adsorbed proteins, the inner of described air inlet pipe extends in implant, air inlet pipe outside buffer container is provided with flow control valve, air inlet pipe between flow control valve and sucking head is provided with attraction flow meter.
The technical problem to be solved can also be realized further by following technical scheme, is provided with drainage screen at the suction catheter mouth of pipe in described buffer container.
The technical problem to be solved can also be realized further by following technical scheme, is provided with the flexible pipe connected with sucking head in the outer end of described air inlet pipe.
The technical problem to be solved can also be realized further by following technical scheme, is provided with Butterworth Hatch on described buffer container, and Butterworth Hatch has rubber pacifier by cleaning pipeline connection, is provided with valve cleaning on pipeline.
The technical problem to be solved can also be realized further by following technical scheme, and described buffer container is bottle, tank body and bag-shaped.
The technical problem to be solved can also be realized further by following technical scheme, and described implant is concrete dynamic modulus filling block.
Compared with prior art, the present invention sets buffer container, adds implant in buffer container, can absorb water or adsorbed proteins, both negative pressure can have been buffered, it is also possible to preventing from causing in liquid or solid protein negative suction suction pump main body the blocking of negative pressure absorber, this buffer container is separable, also can regularly replace and cleaning-sterilizing, reasonable in design, simple in construction, easy to use, take up room little, it is to avoid because negative pressure blocks the high cost that the system maintenance caused brings.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Referring to the drawings, the concrete technical scheme of the present invention is further described, in order to those skilled in the art is further understood that the present invention, and does not constitute the restriction to its right.
Embodiment 1, with reference to Fig. 1, a kind of buffer unit of vacuum extractor, it is provided with buffer container 1, the side of buffer container 1 is provided with the air inlet pipe 3 that the sucking head with vacuum extractor connects, the opposite side of buffer container 1 be provided with connect with vacuum extractor main body suction catheter 6, it is provided with in buffer container 1 and can absorb water and the implant 2 of adsorbed proteins, the inner of described air inlet pipe 3 extends in implant 2, air inlet pipe 3 outside buffer container 1 is provided with flow control valve 5, and the air inlet pipe 3 between flow control valve 5 and sucking head is provided with attraction flow meter 4.
Embodiment 2, the buffer unit of the vacuum extractor described in embodiment 1, it is provided with drainage screen 7 at suction catheter 6 mouth of pipe in described buffer container 1, both can guarantee that and do not affected attraction effect, moreover it is possible to convenient cleaning buffer container.
Embodiment 3, the buffer unit of the vacuum extractor described in embodiment 1, it is provided with the flexible pipe 10 connected with sucking head in the outer end of described air inlet pipe 3, expands the range of activity of vacuum extractor.
Embodiment 4, the buffer unit of the vacuum extractor described in embodiment 1, described buffer container 1 is provided with Butterworth Hatch, Butterworth Hatch has rubber pacifier 9 by cleaning pipeline 8 connection, is provided with valve cleaning on pipeline 8.
Embodiment 5, the buffer unit of the vacuum extractor described in embodiment 1-4, described buffer container 1 is bottle, tank body and bag-shaped.
Embodiment 6, the buffer unit of the vacuum extractor described in embodiment 1-5, described implant 2 is concrete dynamic modulus filling block, such as activated carbon or protein adsorbent.
After the present invention installs, start central negative pressure system, sucking head is positioned over the position that need to absorb, by flexible pipe 10, mobile absorption position, after having blood or solid protein to be sucked out, it is directly entered in the implant 2 of buffer container from air inlet pipe 3, it is adsorbed in implant 2, it is impossible to continue to move to, while absorption, can be by how many control flow control valvees 5 of the content at absorbing position, to adapt to the absorption of different size of content, monitor adsorbance in real time also by attracting flow meter 4, in order to change implant in time or clean buffer container.
