Description

[Detailed Description of the Invention] The present invention relates to a suction device used to reduce the pressure inside the suction device and suck out phlegm from a patient.

Conventional suction devices of this type include those in which a rubber suction bulb is attached to the suction container and the pressure inside the container is reduced by pushing the suction bulb with the hand, or the bellows body connected to the suction container is stepped on with the foot. Some devices are designed to reduce the pressure inside the container.

However, in the former case, the suction force was weak because the suction was carried out by the restoring force of the air intake bulb made of Com, and in the latter case, the bellows body swung while stepping, sometimes causing the user to misstep.

In addition, in order to prevent the swinging movement of the bellows side, a device was developed in which a foot plate installed on the top of the bellows body was moved up and down along a guide pin, but with this, the device was quite large □ and the cost was high. There is a drawback.

The present invention has been made to provide a suction device that eliminates the above-mentioned drawbacks.

Hereinafter, the present invention will be explained in detail based on the illustrated embodiments.

In the figure, 1 is a suction container made of transparent synthetic resin, etc.
A lid body 2 made of rubber or the like is removably fitted into the opening at the upper end.

The lid body 2 is provided with an intake port 3 and a pressure reducing leaf 4, and
One end of a suction pipe 5 of an appropriate length, such as a vinyl pipe, is connected to the intake port 3.

Reference numeral 6 denotes a connecting pipe made of a vinyl pipe or the like, and one end of the connecting pipe 6 is connected to the pressure reducing port 4 via a check valve T.

□The check valve 7 is configured to open only to the outside of the container 1, and in the embodiment, as shown in FIG. A configuration is shown in which a ball 11 is provided and the ball 11 is used to close the valve hole 9 and stop the flow into the container 1.

In this case, the check valve 7 can be of any configuration other than the above-mentioned ball type.
Any configuration is sufficient as long as the flow of pressure into the container 1 is regulated.

12 indicates a suction pump; 13 is a cylinder made of transparent synthetic resin, etc.; it has a suction port 14 at the front; a piston 15 is slidably housed inside;
The front part of the cylinder 13 (suction port 1
4 side).

14a is a projecting tube that communicates with the suction port 14 and projects upward from the front surface of the cylinder 13, and the other end of the connecting tube 6 is connected to the projecting tube 14a.
It is connected to.

17 is a support rod protruding from the front surface of the cylinder 13; 18 is a support ring made of rubber or the like and detachably attached to the support rod 17; the suction container 1 is supported by fitting into the support ring 19; .

19 is a ring 20 fitted into the rear end opening of the cylinder 13
The mounting rods 21a and 21b fixed to the mounting rods 19 are guide rods installed parallel to each other at both ends of the mounting rod 19, and the guide rods 21a and 21b are slidably mounted in the longitudinal direction of the cylinder 13. 21a.

The tip of 21b is connected and fixed by a fixing rod 22.

Reference numeral 23 denotes an operating rod that is located between the mounting rod 19 and the fixed rod 22 and is slidably installed over both guide rods 21a and 21b;
Reference numeral 24 denotes a rod of the piston 15; the outer end of the rod 24 passes through the mounting rod 19 and projects out of the cylinder 13, and the outer end thereof is connected to the operating rod 23.

25 a and 25 b are stoppers provided at both ends of the mounting rod 19 to restrict movement of the operating rod 23 in the direction of the mounting rod while leaving a gap 26 between the mounting rod 19 and the operating rod 23 in which a finger can be inserted; Reference numeral 27 denotes a buffer tube made of an elastic material, which is located between the mounting rod and the operating rod and is fitted onto the rod 24, so that the operating rod 23 can slide between the stoppers 25 a, 25 b and the fixed rod 22. It has become.

28 a and 28 b are elastic plates fixed to the stoppers 25 a and 25 b, respectively, and 29 a and 29 b are both elastic plates 28
Engagement protrusion fixed on the tip side of a, 28 b, 30a
, 30b are provided at the base ends of the guide rods 21a, 21b in correspondence with the engagement protrusions 29a, 29b, and the engagement protrusions 2
9a and 29b, and the guide rod 2 when in use.
1a and 21b are stretched 7 (pulled to the right in the figure)
, the engagement protrusions 29a, 29b are connected to the engagement recess 30a,
30b (see FIG. 1), and when not in use, release the engagement and loosen the guide rods (see FIG. 3).

This allows the device to be made compact, making it convenient for transportation, storage, and the like.

The present invention is based on the above structure, and by inserting a finger into the gap 26, grasping the operating rod 23 and the fixed rod 22, and pulling the piston 15, the pressure inside the container 1 is reduced and phlegm is removed from the suction tube 5. When suction is drawn into the container 1 and the hand is released from the operating rod 23, the piston 15 moves back by the action of the spring 16. This process is repeated to suction out sputum, etc.

This invention has a structure similar to Narukami's, so it has stronger suction power than the conventional rubber ball type, and is easier to operate than the foot-operated type, and is more compact and portable. Since it is convenient and has a simple configuration, it has the advantage of having fewer failures and being able to be mass-produced at low cost.
