Abstract

PROBLEM TO BE SOLVED: To make the great amount of internal secreta or blood absorbed with only one absorber by attaching a tip water absorbing member to the tip of a hollow shaft having an open tip and disposing a shaft internal water absorbing member in the shaft so as to be connected to the tip water absorbing member. SOLUTION: A tip water absorbing member 2 including a PVA(polyvinyl alcohol) having a large water absorbing property is fixed to the tip part of a shaft 1 made of a plastic or metallic pipe material by being bulged to the side or the front so as to cover the tip opening part of the shaft 1. In the shaft 1, a shaft internal water absorbing member 3 made of the same material as the tip water absorbing member 2 is filled from the tip to a part just before a base end part so as to be continuously connected to the tip absorbing member 2. Thus, when the tip water absorbing member 2 is brought into contact with intracorporeal secreta or blood, since blood or the like is absorbed by both absorbing members 2 and 3, the amount of absorption is greatly increased.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical secretion absorbing device for absorbing internal secretions and bleeding.

[0002]

2. Description of the Related Art FIGS. 6 and 7 show a conventional medical secretion absorber. A typical medical secretion absorber is called a cotton swab or a cotton ball, and as shown in FIG. 6, a rod-shaped shaft 91 in which a cotton 92 is firmly fixed to the tip thereof, or as shown in FIG. As described above, there is, for example, a cotton 92 firmly fixed to the tip of a rod-shaped shaft 91, which is further covered with a gauze 93.

[0003] The size of the cotton 92 and the gauze 93 is limited depending on the place where the secretory absorbent is used. For example, the outer diameter of an ear hole, a nostril, an anus, and the like is limited according to the opening diameter, and the outer diameter of an endoscope is limited by the diameter of a treatment tool insertion channel to be inserted.

[0004]

The water absorption capacity (water absorption amount) of the secretory absorbent is determined by the size of the cotton 92 and the gauze 93. Therefore, if the amount of internal secretions and bleeding is slightly large, the conventional secretory absorber as described above cannot be absorbed at once, and it is necessary to replace several secretory absorbers. It was complicated and time-consuming.

[0005] Therefore, an object of the present invention is to provide a medical secretion absorbing device which has a large water absorbing capacity (water absorption amount) and can absorb a large amount of secretions and bleeding in the body.

[0006]

In order to achieve the above object, a medical secretion absorber according to the present invention comprises a hollow shaft having at least an open end, and a water-absorbing material attached to the end of the shaft. And a water-absorbing member in the shaft made of a water-absorbing material, which is filled in the shaft and arranged at the distal end so as to be continuously connected to the water-absorbing member at the distal end.

The base end of the shaft may be closed, and the base end of the shaft may be open. Further, the outer surface of the tip water absorbing member may be coated with a water-permeable cloth, and the shaft may be formed of a flexible tube.

[0008]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a medical secretion absorber according to a first embodiment of the present invention.

The shaft 1 is formed of a pipe material made of plastic or metal, and a distal end water absorbing member 2 made of a PVA (polyvinyl alcohol) sponge having high water absorption is provided at a distal end portion thereof. It protrudes sideways and forward so as to cover and is fixed.

In the shaft 1, a water absorbing member 3 made of PVA sponge of the same material as the water absorbing member 2 at the tip is provided.
It is filled from the distal end to the part slightly before the proximal end.
The water absorbing member 3 in the shaft is provided in a state of being continuously connected to the distal water absorbing member 2.

As a result, when the tip water-absorbing member 2 is brought into contact with internal secretions and blood at a bleeding site, the internal secretions, blood, and the like are absorbed by the tip water-absorbing member 2, and further, the inside of the shaft 1 in the shaft 1 is caused by capillary action. It is absorbed by the water absorbing member 3.

Therefore, the secretory absorbent has much greater water absorption capacity (water absorption) (for example, several times to several tens times) as compared with the one in which the tip water absorbing member 2 is simply attached to the shaft 1, and one time. A large amount of internal secretions, bleeding and the like can be absorbed by the medical secretion absorbing device of the book.

As a result, even if the distal end water absorbing member 2 is formed to be small and small, it has a sufficient absorption capacity. By inserting a secretion absorbing device, treatment such as hemostasis can be performed quickly.

FIG. 2 shows an outer surface of a distal end water absorbing member 2 having a structure similar to that of the first embodiment of FIG. 1 covered with a thin cloth 4 having water permeability such as gauze or the like. This protects the tip water absorbing member 2.

In this embodiment, the base end side of the shaft 1 is closed. The part may be open or closed. When opened, the water absorption speed of the water absorption member 3 in the shaft due to the capillary phenomenon increases.

The material of the tip water absorbing member 2 and the shaft water absorbing member 3 is not limited to PVA sponge, but may be cotton,
Various water-absorbing materials such as sponge and water-containing polymer material can be used, and may contain a surfactant.

FIG. 3 shows a third embodiment of the present invention, in which gauze is packed in the shaft 1 as the water absorbing member 3 in the shaft, and further tightly wound around the outer surface of the tip portion of the shaft 1. This is the tip water absorbing member 2.

FIG. 4 shows a fourth embodiment of the present invention, which is an endoscope secretion absorber used through a treatment tool insertion channel of a flexible endoscope (flexible scope). .

In this embodiment, the shaft 1
Is formed of a flexible tube made of ethylene tetrafluoride, polyethylene, polypropylene, fluororesin, or the like. Various materials can be used for the tip water absorbing member 2 and the shaft water absorbing member 3 as in the second embodiment. The length of the shaft 1 is longer than the length of the insertion portion of the endoscope, for example, about 50 cm to 200 cm.

The rear end surface portion 2a of the distal end water absorbing member 2 is formed into a smooth tapered surface so as not to be caught when it is extracted from the treatment instrument insertion channel of the endoscope. The cloth body 4 may or may not be provided.

The endoscope secretion absorber of the fourth embodiment thus formed is passed through the treatment tool insertion channel 11 of the endoscope 10 as shown in FIG. Bleeding site 1 in the body cavity so that the mucosal surface of the
It is used, for example, to absorb blood output of 00.

When the secretory absorbent passes through the treatment instrument insertion channel 11, the water in the treatment instrument insertion channel 11 is absorbed by the distal water absorption member 2 and the shaft water absorption member 3, but the water absorption in the shaft is prevented. Since a large amount of water can be sucked into the member 3, even after the distal water absorbing member 2 is protruded from the distal end of the treatment instrument insertion channel 11, blood can be sufficiently absorbed.

[0023]

According to the present invention, a tip end water absorbing member made of a water absorbing material is attached to the tip end of a hollow shaft, and the shaft absorbing member inside the shaft made of a water absorbing material is continuously connected to the tip end water absorbing member. By filling the inside, the water absorbed by the tip water absorbing member is further absorbed by the water absorbing member in the shaft, so that the water absorbing capacity (water absorption amount) is very large, and the secretion absorbing device is used by one secretion absorbing device. Bleeding and the like can be absorbed in large amounts, and the work of absorbing internal secretions can be performed easily and quickly.
