Description

[Detailed Description of the Invention] [Background of the Invention] (1) Technical Field This invention relates to a catheter storage protector that encloses a catheter along its longitudinal direction for the purpose of aseptically inserting the catheter into a blood vessel or the like. .

(2) Prior art and its problems For the purpose of aseptically inserting a catheter into a blood vessel, etc., the catheter is wrapped along its longitudinal direction in a flexible synthetic resin cylindrical bag, and when used, this bag is There are two types of catheters, one in which the catheter body is peeled off, and one in which the catheter is encapsulated in a relatively hard tube body and the tube body is pulled back during use to expose the catheter tip. In order to avoid accidental exposure and contamination, a cap, etc. is required at the tip, which increases the number of parts and increases costs. There are drawbacks that require it.

In addition, as shown in Fig. 3, a catheter is proposed in which the catheter is enclosed in a tube body 2 with a slit 1 formed in the longitudinal direction, and when in use, the tube body 2 is peeled off and the catheter 3 is taken out and inserted into a blood vessel or the like. However, while the one shown in Fig. 3 is inexpensive and easy to use, it is necessary to expose the catheter tip 3a slightly from the tube body 2 in advance as shown in Fig. 4 in order to make it easier to insert the catheter into the catheter introduction needle. Therefore, in order to protect the catheter in a sterile manner, a separate member such as a cap is ultimately required.

[Objective of the Invention] It is an object of the present invention to provide a catheter housing and protector that allows the aseptic insertion of a catheter into a blood vessel or the like without requiring a separate member such as a cap or a complicated structure, and which is easy to use. purpose.

That is, the invention comprises a catheter and a flexible tubular protector whose distal end extends beyond the distal end of the catheter and encases the catheter; the protector extends longitudinally from the base of the catheter. It is characterized by having a first slit at least in the portion leading to the tip of the catheter, and further having a second slit that crosses the first slit at a position near the tip of the catheter on the proximal side of the catheter from the tip of the catheter. The present invention provides a protective body housing a catheter.

Furthermore, in the protector housing the catheter, the second slits are arranged approximately equally on both sides of the tube protector from the point of intersection with the first slit, and extend in the circumferential direction of the tube protector by 25 to 75% of the circumferential length thereof. More preferably, the length is cut by 25 to 50%.

Furthermore, the present invention provides a protective body housing the catheter, in which two or more of the second slits are provided spaced apart from each other.

[Specific Description of the Invention] The present invention will be described below with reference to an illustrated embodiment.

FIG. 1 shows a perspective view of a main part of a catheter storage protector according to the present invention, and shows a catheter 1.
1 is encapsulated by a flexible tubular protector 12 from the proximal end to the distal end. A first slit 13 is formed in this protector 12 over its entire length in the longitudinal direction. The shape of the circumferential cross section of the protector 12 does not need to be circular, and may be polygonal or the like as long as it does not pose a problem in taking out the catheter.
It should be noted that the first slit 13 does not necessarily have to be formed completely up to its distal end as shown in the figure, but may be formed up to the distal end of the catheter 13.

A second slit 14 is further cut into the tip of the protective body 12 so as to cross the first slit 13 perpendicularly, for example. It is preferable that the cut position of the second slit 14 be provided at a position offset, for example, about 5 to 50 mm toward the catheter proximal side from the distal end 11a of the catheter 11. Further, the second slits 14 are approximately equally spaced on both sides from the intersection with the first slit 13 and have a length of 25 to 75%, more preferably 25 to 50%, of the circumferential length of the protector 12. . The shallower the incision depth within this range, the longer the length of the fold line 15 shown in FIG. 2 becomes, and the opening width becomes wider, making it easier to take out the tip of the catheter. Therefore, this cutting depth is
If it is more than 75%, the width of the fold line 15 becomes narrower, making it difficult to take out the catheter 11, which is not preferable.

Further, the number of second slits 14 may be two or more as required. The slit widths of the first and second slits 13 and 14 are preferably such that they are in close contact with each other, that is, the width is 0, but in some cases, the second slit may be slightly open. No problem. In addition, the protective body 12
A relatively flexible synthetic resin may be appropriately selected as the material.

When using the catheter housing protector as described above, first pinch the tip of the protector 12 and bend it in the opposite direction to the position of the second slit 14 as shown in FIG. The tip of 14 parts will be automatically exposed. Then, this exposed catheter 11 is easily broken,
Thereby, the catheter 11 is used, for example, by being inserted into a catheter introduction needle.

Further, the number of second slits 14 may be two or more as required. The widths of the first and second slits 13 and 14 are usually such that they are in close contact with each other, but in some cases, they may be slightly open. Note that as the material of the protector 12, a relatively flexible synthetic resin may be appropriately selected.

When using the catheter housing protector as described above, first pinch the tip of the protector 12 and bend it in the opposite direction to the position of the second slit 14 as shown in FIG. 14 will be easily broken off, thereby automatically exposing the distal end of the catheter 11. Then, this exposed catheter 11 is used, for example, by being inserted into a catheter introduction needle.

[Effects of the Invention] As described in detail above, the catheter storage protector according to the present invention has a longitudinal slit in the protector for enclosing the catheter, and a second slit across the slit at a position recessed from the tip of the catheter. Since the tip of the catheter does not need to be exposed from the protector in advance as in the conventional example shown in Fig. 4, it can be completely housed inside the protector and is protected aseptically. Separate members such as caps are not particularly required. Furthermore, when taking out the catheter, simply bending the tip of the protector allows the tip of the catheter to be exposed to a large extent in an extremely easy-to-handle state, making it extremely easy to use.
