No. 8). Further, as a cap for closing the fluid port port of such a three-way cock to prevent the attachment of dust and the like,
A cap comprising a cap body and a string-shaped holder has been proposed (for example, JP-A-61-293467), and the holder is attached to the body of the three-way cock or the fluid port to prevent the cap from being lost. I have to.

[0003]

[Problems to be Solved by the Invention] However, in the case where a cap is attached to a three-way stopcock or the like using a holder or the like, when the cap is removed after removing the cap, if a syringe or a catheter is to be connected to the three-way stopcock, joining is required. May be an obstacle.

The present invention has been made to solve the above-mentioned problem, and has a cap with which a removed cap is not lost and which does not become an obstacle even when a syringe or a catheter is connected to a three-way cock. The purpose is to provide a three-way stopcock.

[0005]

In order to achieve the above object, the present invention is directed to a cylindrical body and first to third bodies formed on an outer peripheral surface of the body and communicating with an internal space of the body. A fluid port port and a cap fitted to one of the fluid port ports, in a three-way cock comprising a cock body liquid-tightly and rotatably fitted to the body;
And a storage hole formed in an upper part of the cock and into which a cap is fitted.

[0006]

In a state where the fluid port port to which the syringe or the like is connected is not used, a cap is fitted to this port to prevent dust and the like from entering and adhering to the inside of the cock. Also, when connecting a syringe, the cap is removed from the fluid port port. The removed cap is fitted in a storage hole formed in the upper part of the cock. For this reason, loss of the cap can be prevented. In addition, since the cap is held in a state of being fitted to the storage portion, no dust adheres to the inner peripheral surface or the like of the cap, and the cap is kept clean. In addition, the cap does not fluctuate and does not hinder the connection of the catheter or the syringe.

FIG. 1 is a perspective view showing a three-way cock with a cap embodying the present invention. The three-way cock 10 is composed of a transparent synthetic resin cylindrical body 11 and a synthetic resin cock body 12 which is fitted in a liquid-tight and rotatable manner. The body 11 has three fluid port ports 1
3, 14, 15 are formed so as to protrude at an interval of 90 ° in the circumferential direction, and each port 13 to 15 has a T-shape.

The outside of the first fluid port port 13 is formed in a telescope shape in which tapered surfaces 13a and 13b are stacked in multiple stages. The tapered surface 13a is for a small diameter tube, and the tapered surface 13b is for a larger diameter tube or catheter. Thus, the tapered surface 13a having a small diameter and the tapered surface 13b having a larger diameter
Are connected, tubes having different diameters such as a nasal gastric tube catheter and a feeding tube can be joined.

The outside of the second fluid port port 14 is a male luer lock connector 14a. In addition to the straight tube, a female luer lock connector 15a is provided.
Various tubes such as the suction tube 15 having a can be joined. As shown in FIG. 2, the inside of the second fluid port port 14 is a female luer slip connector having a tapered surface 14b, so that the feeding pump tube 16 and the like can be joined.

The third fluid port 15 is used as a medical port, and as shown in FIG. 3, is a female luer slip connector having a tapered surface 15a to which a catheter tip syringe 18 can be connected.

A red cap 25 is fitted in the third fluid port 15. The cap 25 is formed of a bottomed cylindrical body made of a synthetic resin, and has an inner peripheral surface 25 a (see FIG. 4) fitted to the outer peripheral surface of the third fluid port 15. A flange 27 is formed on the bottom 26 of the cap 25 so that the cap 25 can be easily removed. The inner peripheral surface is tapered so as to guide insertion when the cap 25 is fitted, so that the cap 25 can be easily fitted.

As shown in FIGS. 4 to 6, a T-shaped communication passage 30 is formed in the cock body 12 at a position corresponding to each of the ports 13 to 15. As shown in FIG. 4, the upper part of the cock body 12 is aligned with the direction of the communication passage 30,
Handles 31, 32, 33, 34 at 90 ° intervals in the circumferential direction
Are formed to protrude. Arrows 35 indicating the flow direction of the fluid are embossed on the handles 31 to 33 at positions corresponding to the T-shaped communication passages 30, and the upper surface of the arrows is coated with red paint. In addition, the communication passage 30
The handle 34 in the position where is not formed is formed longer than the other handles 31 to 33, and the "OFF" character 36 indicating that the fluid does not flow is embossed on the handle 34. Red paint is applied to the upper surface of the character. As described above, since only the handle 34 of the off display is formed long, the direction of the cock body 12 can be easily understood. Therefore, it is possible to prevent a mistake in the switching operation of the cock.

On the upper part of the cock body 12, a cap 25 is provided.
Are formed. The storage hole 40 is formed in a taper slightly larger than the outer diameter of the cap 25, so that the cap 25 can be inserted smoothly. Instead of forming the storage hole 40 in a tapered shape, the outer peripheral surface of the cap 25 may be formed in a tapered shape.

Next, the operation of this embodiment will be described. As shown in FIG. 7, after the nasal gastric tube catheter 50 is set in the patient, it is connected to the first fluid port 13. In addition, a straight sump tube 51 is connected to the second fluid port 14. Thereafter, the cock body 12 is turned so that the third fluid port 15 is in the off position, and suction is performed. After the suction, the cock body 12 is turned so that the handle 34 of the OFF display faces the fluid port port 13 on the patient side to prevent the aspirated liquid from scattering, and the second fluid port 1
Remove the tube from 3. As described above, when the third fluid port 15 is not used, since the cap 25 is fitted and closed, it is possible to prevent dust and the like from entering and adhering to the cock. .

[0015] When nutrition is to be supplied,
After a feeding tube (not shown) is connected to the second fluid port port 14, the cock body 12 is turned so that the handle 34 in the OFF state is positioned at the third fluid port port 15.

When a drug is to be administered, as shown in FIG. 8, a nasal gastric tube catheter 50 is set on a patient 55 and then connected to the first fluid port 13. The cock body 12 is turned so that the handle 34 in the OFF state is located at the position of the second fluid port 14. Thereafter, the cap 25 is removed from the third fluid port 15 and fitted into the storage hole 40 of the cock body 12. Next, the cap 25
The catheter tip syringe 56 for administration is connected to the fluid port port 15 from which the liquid has been removed, and the liquid medicine is injected. After the completion of the administration, the handle 43 of the off display is connected to the third fluid port port 15.
Then, the cock body 12 is turned so as to be in the position, and then the syringe 56 is removed from the port 15. Then, storage hole 4
The cap 25 is removed from 0, and the cap 25 is returned to the third fluid port 15 as shown in FIG. in this way,
When the third fluid port 15 is used, the cap 2
5 is inserted into the storage hole 40 for storage.
No dust or the like enters or adheres to the inside of the housing 5. Moreover, since the storage hole 40 is securely stored and held, the cap 25 does not hinder the connection of the syringe 56.

In the above embodiment, the case of feeding the gastric tube and supplying the medical solution has been described. A three-way stopcock can be used.

In the above embodiment, the fluid port 15
Although the cap 25 that is externally fitted so as to cover the outer peripheral surface of the fluid port port 15 is used, an internal fitting type cap that is inserted inside the fluid port port 15 may be used.

[0019]

As described above, according to the present invention, a cap is fitted to one of the fluid port ports, and when this port is used, the cap is removed and the storage hole formed in the upper part of the cock body. Since the cap is fitted to the cap, loss of the cap can be prevented. In addition, since the cap is usually fitted to the fluid port, it is possible to reliably prevent dust or the like from entering or attaching to this port.

In addition, since the cap is stored in a state fitted in the storage hole, unlike the case where the cap is prevented from being lost by a string-shaped holder or the like, the cap is stably held in the storage hole. Since the cap does not become an obstacle when a syringe or the like is connected, the operation can be easily performed. And because the cap fits into the storage hole,
No dust or the like enters or adheres to the cap when the cap is not used.
