Description
Technical field
The present invention relates to medical instruments field more particularly to a kind of suction tubes.
Background technique
Existing suction tube is by the way of vacuum suction, in actual use, it may appear that following scenario described:
1, it is obviously reduced in the organ for having inner cavity in use, will lead to organ lumen pressure, causes organ lumen local
Deformation, brings sense of discomfort, such as lung to patient, when suction tube suction sputum, will lead to pressure in tracheae or bronchus and declines, lumen
It deforms therewith, patient feels extremely unbearably；
2, when suction tube is applied to operation or suction port is affixed on organ inner wall, tissue is usually drawn onto suction port inner cavity,
Block suction port, can not be attracted, while attracting tube cavity because negative pressure persistently attracts, attracts the indeformable condition of tube cavity
Under, it causes that intraluminal pressure is attracted to continue to decline, i.e. the pulling force of negative pressure formation is increasing, can lead to tissue damage, or even tear
Lacerated wound or bleeding.If pulling open suction tube by force, tissue damage is also resulted in.
3, when tissue, which is attracted pipe, is drawn into inner cavity, current usual processing mode be stop continuous negative pressure suction or
Opening side gas inlet hole makes negative pressure state in suction tube disappear, while tissue springback (may be damaged may also not have), it is desirable to be inhaled
The liquid phlegm or blood of carrying-off can flow back into original position again.
Summary of the invention
The present invention is intended to provide a kind of differential suction tube, will not cause organ lumen pressure to significantly reduce, and attract
Power size is relatively stable, easily controllable, and non-free continuous tissue will not be attracted to enter and attract tube cavity, avoid because organize into
Enter to attract tube cavity, the damage to tissue, and then stop attracting caused by reducing therefore, is attracted object sputum and blood returns
Stream.
In order to achieve the above objectives, realization that the present invention adopts the following technical solutions:
Differential suction tube disclosed by the invention, including single channel suction tube, the single channel suction tube include that negative pressure is inhaled
Draw channel and gas passage, the front end in the vacuum suction channel is docked with the front end of gas passage, vacuum suction channel rear end
Connect continuous negative pressure equipment, the side wall of vacuum suction channel and/or gas passage offers suction port, after the gas passage
End opens up air inlet.
Further, the suction port at least there are two.
As one preferred, the axis in the vacuum suction channel is overlapped with the axis of gas passage, the suction port
It is raised or not raised.
Preferred as another kind, the leading portion in the vacuum suction channel and the leading portion of gas passage are located at same tube body
Interior, the axis of leading portion of leading portion and gas passage in vacuum suction channel is parallel, and the suction port is located at the front of tube body, described
The back segment in vacuum suction channel and the back segment of gas passage are separately positioned.
Further, the invention also includes supervisor and air bag, the single channel suction tube at least there are two, the air bag connects
It connects in one end of supervisor, is equipped with gas injection channel in the supervisor, gas injection channel communicated air bags are additionally provided with main attraction in supervisor
Channel and main gas passage, the vacuum suction channel are connected to main attraction channel, and the air inlet is connected to main gas passage, single-pass
Road suction tube is attached to balloon surface.
Preferably, when the air bag empties, the axis projection of all single channel suction tubes is respectively positioned on the axis projection of supervisor
In range；When the air bag fills, the front end of single channel suction tube is inclined outwardly.
Preferably, when air bag is full, the radial dimension of air bag front is greater than the diameter of supervisor.
Preferably, suction port is located at the opposite face of the side of single channel suction tube and air bag attachment, single channel suction tube
Front end of the front end without departing from air bag.
Preferably, the gas injection channel, main attraction channel, main gas passage all extend to outside supervisor.
Preferably, the material of the single channel suction tube is medical plastic, medical silica-gel or medical metal.
Working principle of the present invention is as follows:
1, single channel suction tube
The front end in vacuum suction channel and the front end of gas passage are located in organ, and vacuum suction channel rear end is persistently born
Pressure equipment persistently attracts gas, so that passing the gas through gas passage enters the outflow of vacuum suction channel, the gas of above-mentioned flowing
Speed difference is formed between gas opposing stationary outside suction tube, according to bernoulli principle, fluid (sputum, blood or other streams
Body) vacuum suction channel and/or gas passage can be entered by suction port, to be sucked out by negative pressure by vacuum suction channel.
2, multichannel suction tube
There is the case where multiple single channel suction tubes and additional supervisor and air bag, reset condition lower gasbag is emptying,
Since branch pipe has certain hardness, the axial direction of branch pipe and axially retaining unanimously, by branch pipe and supervisor under this kind of state for supervisor
Leading portion be sent into vivo, then air bag is inflated by gas passage, after air bag is full, pushes branch pipe to be inclined outwardly, then opens
The continuous negative pressure equipment being connected on attraction channel is opened, attraction operation is carried out.
Beneficial effects of the present invention are as follows:
1, the present invention will not cause the pressure in tissue lumen to be decreased obviously, and will not cause organ lumen local deformation, reduce
Sense of discomfort, such as lung are brought to patient, when suction tube suction sputum, pressure in tracheae or bronchus is not will lead to and declines, lumen is not
It can deform therewith, patient feels extremely unbearably, and then to reduce the sense of discomfort of patient during attraction.
2, the present invention can be avoided non-free continuous tissue and be drawn into suction port, lead to tissue damage.
3, obstruction suction port is avoided, causes to attract and interrupt, be attracted object and backflow.
4, the present invention carries out suction sputum using multichannel, can shorten the time for attracting operation, mitigate the pain of patient.
5, due to the presence of air bag, the front end of multichannel suction tube will not touch interior wall tissue, can be avoided interior wall tissue
Block suction port.
6, due to the presence of air bag, the opportunity of branch pipe opening can be controlled, and does not influence being put into for suction tube.
