Description

[Detailed description of the invention] This invention relates to an extension tube for suctioning blood, etc., which is connected to a medical suction device, and its purpose is to remove blood, exudate, pus, cleaning fluid, etc. To provide an extension tube for suctioning blood, etc., which can absorb secretions and at the same time stably suction them and remove them from a surgical field, and which can be easily replaced from a gas suction device.

Conventionally, during surgery, an absorbent material made of cut compressed plates such as absorbent cotton, gauze, or viscose material was held with tweezers.
Alternatively, an absorbent material with a handle was used to absorb and remove blood and exudate from the surgical site, but since a considerable amount of absorbent material was required for one operation, the assistant or nurse had to work frequently, resulting in a time-consuming task. It was something like that.

On the other hand, there are adapters for continuous suction in dentistry and surgical procedures, but if tissue is sucked into or comes into close contact with the suction hole at the tip, suction becomes impossible, or the tip of the suction hole closes to the surgical site. There were also problems such as damage to tissues around the surgical site.

For this reason, a suction force regulator was used to connect the suction force regulator and release the suction pressure as soon as the tissue was adsorbed.
However, they still adsorbed tissue, sometimes damaging blood vessels and causing heavy bleeding, or destroying some vital organs.

In addition, none of the suction extension tubes had a structure in which the middle part could be removed, and this resulted in a drawback that it was time-consuming when it was desired to quickly replace the suction tube with the suction section attached.

The present invention was made to improve the suction part, that is, the extension tube part of the conventional medical suction device described above. A suction part is provided by inserting it into a breathable and water-absorbing molded material such as a cavernous body or polyurethane foam with open cells, and the other end is provided with a connecting adapter for connecting to the tube of a suction device. This is an extension tube for suctioning blood, etc., which is characterized by:

The extension tube for suctioning blood, etc. of the present invention has a suction section made of a molded material with excellent water absorption and air permeability at one end of the tube.

The molded material for the suction part can be easily obtained in various shapes, from those with protruding tips to those with semicircular shapes, so there is an advantage that the suction part can be applied according to the treatment purpose. be.

For example, the removal of blood, exudate, etc. during eye surgery, etc.
By using a suction part with a sharp tip, it is possible to effectively treat even small parts of the gap without irritating the eyes.

Also, if there is a lot of blood, clots may adhere to the surface of the tip,
Even if the suction power decreases, it can be regenerated by washing the tip several times in physiological saline, so it is only necessary to use one suction extension tube for one surgery, and the extension tube The other end has a replaceable connection adapter, so when the suction power decreases due to foreign matter adhering to the suction part, you can easily connect the suction extension tube without moving the suction device attached to the extension tube. Can be easily replaced.

Hereinafter, the configuration of the extension tube for suctioning blood, etc. of the present invention will be explained based on the drawings.

The drawings show an embodiment of the present invention, and FIG. 1 is a perspective view of an extension tube for suctioning blood, etc. when the present invention is applied to ophthalmology, and FIG. 2 is a partial sectional view of FIG. 1. .

The tip member 1 is made of a highly breathable and water-absorbent nonwoven fabric, a cavernous body, a polyurethane foam having open cells, or the like.

The distal end of an extension tube 2 made of a plastic material having a suction hole 21 at the distal end is inserted and fused to the distal end member 1, and the other end is connected to an aspirator (
(not shown), and the suction tube 4 is further connected to a suction device.

Fig. 3 shows an example of a surgical application, in which the tip member 1 does not require a sharp corner like that used for ophthalmology, and is approximately oval-shaped so that it can be easily inserted into the underside of an organ during surgery. Good too,
The suction extension tube 2 may also be bent in advance so that it can be easily inserted.

Alternatively, depending on the content of the surgery, the suction extension tube 2 may be made of a soft material.

For dental use, connect suction extension tube 2 to U.
It may also be formed into a letter shape.

Figure 4 shows an example of use in minute surgeries such as otorhinolaryngology, neurosurgery, and blood vessel suturing. For this purpose, a diaphragm portion 22 is provided, and the tip member 1 may be provided with an acute angle portion such as for ophthalmology.

Alternatively, a relatively large distal end member 1 can be fused to the suction extension tube 2 and then cut to be easily used depending on the content of the surgery.

According to the present invention, unlike conventional ophthalmological absorbent materials, it does not require as much time and effort, does not cause tissue to stick to the suction hole and become impossible to aspirate, and does not damage the surgical site or the tissues around the surgical site.

Blood and exudate are once absorbed into the distal end member 1, and then through the opening of the extension tube 2 and the numerous suction holes 21.
Even if the distal end member 1 is partially covered with tissue, suction will not be hindered.

In other words, the present invention combines wiping and suction with absorbent cotton or gauze during surgery, and simultaneously absorbs and suctions blood, exudate, pus, washings, and other secretions that occur during surgery. This is an extremely practical device that can be quickly and easily removed from the surgical field.
