BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a suction connector used in connection with a catheter.

[0002]

2. Description of the Related Art A suction connector used at present has a liquid passage formed in a main body, and a suction passage and a vent are branched from the liquid passage. In use, connect the catheter to be inserted into the affected part of the patient to the distal end of the liquid passage, hold the ventilation port with a finger, adjust the opening / closing state of the ventilation port, aspirate patient dirt, etc. Had been adjusted.

[0003] However, blood and dirt may flow back and adhere to the finger holding the ventilation hole, which is not only unfavorable for the hygiene of the worker but also causes a risk of causing an infection to the worker. The inventor of the present invention has conducted intensive studies to solve the above problems, and has arrived at the following invention.

[0004]

FIG. 1 is a schematic view showing a suction connector 1 according to the present invention, and FIG. 2 is a longitudinal sectional view of FIG. In the suction connector 1, a liquid passage 3 is formed in a main body 2, and a suction passage 4 and a vent 5 are formed in a Y-shape continuously from the liquid passage 3. The liquid passage of the main body 2
A connecting pipe 3a of the catheter is formed in front of the passage 3 formed.
A suction device is provided behind the main body 2 where the suction passage 4 is formed.
A connection pipe 4a is formed. The suction passage 4 and the vent 5 are arranged parallel to the length direction of the main body 2, and a filter 6 is loaded in the vent 5. The filter 6 is made of a synthetic resin that allows gas such as polyethylene, polypropylene, and polyethylene terephthalate to pass, but not liquid.

[0005] The method of using the suction connector 1 is as follows. Connect the catheter to the connecting tube 3a of the catheter,
Insert the suction hole of the catheter into the affected part of the patient. Aspirator
When the connection pipe 4a is connected to the suction device and the ventilation port 5 is closed while suction is performed by the suction device with the ventilation port 5 opened, blood, dirt, and the like are sucked from the affected area through the liquid passage 3 through the suction passage 4. . The degree of opening of the vent 5 is adjusted according to the quality and quantity of blood and dirt. After the suction is completed, the vent 5 is opened, and the catheter is removed from the affected part.

FIG. 3 is a schematic view showing another embodiment of the present invention, and FIG. 4 is a longitudinal sectional view of FIG. Suction connector 1
In 1, a liquid passage 13 is formed in a main body 12, and a suction passage 14 and a vent 15 are formed to be branched from the liquid passage 13. Forming a liquid passage 13 in the body 12
A connecting tube 13a for a catheter is formed in front of the book.
A suction pipe connecting pipe is formed at the rear of the body 12 after forming the suction passage 14.
14a is that has been formed. The ventilation port 15 is provided so as to protrude from a side portion of the main body 12, and a flange portion 17 is formed at an upper portion. A filter 16 is loaded in the vent 15.
The method of use is the same as that of the suction connector 1 and will not be described.

[0007]

As described above, since the liquid path 3 of the suction connector 1 is branched into the Y-shaped suction path 4 and the ventilation port 5, blood, dirt, and the like can be transferred from the suction path 4 to the liquid path 3. Even if it flows backward in the direction of the tip, it does not easily flow backward in the direction of the ventilation port 5, and even if it flows backward, it can be prevented from flowing out of the ventilation port 5 from the filter 6. The suction connector 11 has a ventilation port 15 protruding from the side of the main body 12 and branches the ventilation port 15 in the middle of the liquid passage 13 so that suction is performed.
Even if the patient's blood, dirt, and the like flow backward from the passage 14 toward the distal end of the liquid passage 13, it is difficult for the blood to flow back toward the vent 15.
5 can be prevented from flowing out. Further, since the flange portion 17 is formed on the upper portion of the vent hole 15, a finger is put on the flange portion 17 to easily adjust the opening / closing state of the vent hole 15, and it is easy to perform a suction operation of blood, dirt, etc. of the patient. .
