Abstract

The utility model relates to an open type multi-slot drainage tube used after the operation of patients. At present, the drainage tube in use is in a round tube shape, a plurality of side holes are arranged at the front end head that is the near-end wall of the drainage tube, and an inner cavity of the drainage tube is communicated with the side holes. The design is not perfect in that when the blood clot appears after the operation, the inner cavity of the tube or/and the side holes is/are blocked, namely, the drainage is impeded, and the drainage effect is poor; moreover, the diameter of the drainage tube is relatively larger, therefore, the drainage tube has great damage to the patients and poor safety performance and is inconvenient to use clinically. The near end of the drainage tube employs an open type multi-slot structure, and the far end of the drainage tube employs a round tube shaped structure; and all inner tube cavities of the near end of the drainage tube are communicated with tube cavities of the far end of the drainage tube thereby achieving the effects that the drainage is good, the smaller damage can be caused to the patients, the use is convenient, and the safety of the patients can be improved.

Description

Smooth open type multiple-grooved drainage tube

One, affiliated technical field

This utility model relates to the perform the operation drainage tube of back drain blood of a kind of patient of being used for.

Two, background technology

At present, after patient's operation, its used drainage tube is a tubular, and the leading portion head also is that drainage tube proximal tube cornice has several side openings, and tube cavity communicates with side opening.This design is perfect not to the utmost, and when blood clotting occurring after patient's operation, tube cavity is or/and side opening is prone to obstruction, be that drain will be not smooth, drainage effect is bad, and the drainage tube diameter is thick relatively,, poor safety performance big to patient trauma are used inconvenient clinically.

Three, summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of novel smooth open type multiple-grooved drainage tube that uses after patient performs the operation is provided; Its drainage tube near-end i.e. the smooth open type multiple groove structure of point (drainage tube is placed in the patient body) employing special shape from the drainage tube head to witness marker, and the drainage tube far-end is promptly put drainage tube from witness marker and connected negative pressure drainage vessel seam (drainage tube is outside the patient body) employing tubular type structure; A plurality of inner chambers of drainage tube near-end communicate with the drainage tube distal lumen.It is good to have reached drainage effect, less to patient trauma, easy to use, improves patient safety.

The purpose of this utility model realizes with following proposal:

Smooth open type multiple-grooved drainage tube, form a pipe by drainage tube proximal part 6 and distal portions 7, it is characterized in that: drainage tube proximal part 6 adopts smooth open type multiple groove structure, be that a plurality of tube wall grooves 2 are arranged on its tube wall 1, a plurality of interior tube chambers 8 are arranged in the tube chamber, every tube wall groove 2 communicates with corresponding interior tube chamber 8, and each tube chamber 8 is separated by by interior tube chamber frame 9, a plurality of in tube chambers 8 communicate with drainage tube far-end tube chamber 10.

Described smooth open type multiple-grooved drainage tube is characterized in that: drainage tube near-end 6 is a witness marker point 3 with the separation of far-end 7, and drainage tube proximal part 6 is entirely in the patient body before this witness marker point 3.

Described smooth open type multiple-grooved drainage tube is characterized in that: a painted development line 4 is arranged on the drainage tube tube wall.

Effect of the present utility model is: a plurality of tube wall grooves 2 are arranged on the tube wall 1 of drainage tube near-end 6, a plurality of interior tube chambers 8 are arranged in the tube chamber, effusive blood of patient or liquid flow in the interior tube chamber 8 by tube wall groove 2, tube wall groove 2 is smooth open architecture, big with people's in-vivo tissue contact surface, drain blood or other liquid easily by negative pressure and siphonage, and prevent blood clotting from blocking and influence drain.This utility model is rational in infrastructure, adopts smooth open type multi-groove structure under the condition that does not increase the drainage tube diameter, and drainage effect is good, and is less to patient trauma, easy to use, improved patient safety.

Five, the specific embodiment

Describe this utility model embodiment in detail below in conjunction with accompanying drawing.

After patient's operation, according to the difference of modus operandi and operative site, place 1-2 root drainage tube usually, can place many drainage tubes of 5-10 at most; The far-end of every drainage tube links to each other with drainage bag or negative pressure drainage vessel, is used for the postoperative blood of drain patient or other liquid.

Referring to Fig. 1, Fig. 2 and Fig. 3, drainage tube is made up of drainage tube proximal part 6 and distal portions 7; Drainage tube near-end 6 i.e. the smooth open type multiple groove structure of 3 (drainage tube is placed in the patient body) employings from the drainage tube head to witness marker point, and drainage tube far-end 7 is promptly put drainage tube from witness marker and connected negative pressure drainage vessel seam (drainage tube is outside the patient body) employing tubular type structure; The formed a plurality of interior tube chambers 8 of the multiple groove of drainage tube near-end 6 communicate with drainage tube far-end tube chamber 10.Tube chamber 8 in blood or liquid flow into by drainage tube near-end tube wall groove 2, a plurality of interior tube chamber 8 of near-end flows into the far-end tube chamber 10 of drainage tube again, and the far-end of drainage tube and the interface of drainage bottle join and enter drainage bottle.A painted development line 4 is arranged on the tube wall of drainage tube, and development line 4 does not see through rays such as X-ray, and operation back inspection can be observed drainage tube in the intravital position of patient.Witness marker point 3 is arranged on the tube wall of drainage tube, and in the patient body, witness marker point 3 is near skin entirely for proximal part 6 when placing drainage tube.

Referring to Fig. 4 Fig. 5, the smooth open type multiple groove structure of drainage tube near-end 6 is that four chambeies are that near-end tube chamber 8 is four chambeies with spline structure, and corresponding tube wall groove 2 also is four, forms " ten " font inner chamber frame 9; When the smooth open type multiple groove structure of drainage tube near-end is that three chambeies are that near-end tube chamber 8 is three chambeies with spline structure, corresponding tube wall groove 2 also is three, forms " Y " font inner chamber frame 9; The smooth open type multiple groove structure of drainage tube near-end is that two chambeies are that near-end tube chamber 8 is two chambeies with spline structure, and corresponding tube wall groove 2 also is two, forms " one " font inner chamber frame 9.

Operation principle: drainage tube near-end 6 is put into patient's operative site, a plurality of tube wall grooves 2 are arranged on the tube wall 1 of drainage tube near-end 6, a plurality of interior tube chambers 8 are arranged in the tube chamber, patients'blood or liquid flow in the interior tube chamber 8 by tube wall groove 2, enter far-end tube chamber 10 again, flow into drainage bottle at last; Tube wall groove 2 is smooth open type multiple groove structure, and is big with people's in-vivo tissue contact surface, easily drains blood or other liquid by negative pressure and siphonage, and prevents blood clotting from blocking and influence drain.Negative pressure is produced by negative pressure drainage vessel.
