Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a medical clamp used to occlude a resilient tube to stop fluid flow within the tube. More specifically, in a medical clamp that is made of a rigid plate-like member and has a continuous hole that includes an opening that accommodates an elastic tube without blocking it and a squeeze portion that closes the elastic tube, This invention relates to a medical clamp characterized in that depressions are provided on both sides in opposite directions to the plate surface so that an elastic tube can be housed parallel to the plate surface without bending.

Conventionally, in infusion systems, blood collection/transfusion systems, urine collection systems, dialysis systems, etc.
Elastic tubes made of soft plastic, rubber, etc. are used in circuits for flowing liquids and gases, and various clamps are used to stop the flow and adjust the flow rate. There are various types of clamps, and they are used depending on the purpose of use. Among them, flat clamps called plate clamps have a simple structure and are easy to manufacture, so they are often packaged and sold together with various products that use elastic tubes. At this time, it is convenient to package with the clamp attached to the tube, but if pressure is applied to the package when packaged with the clamp attached, the tube and clamp will become parallel to each other. As shown in FIG. 1, it often happens that the tube is bent and the bent portion does not return to its original shape even after unpacking. Medical tubes are often used after being heat sterilized,
The above phenomenon occurs particularly frequently when heat sterilization is performed after packaging. Therefore, in the past, the clamp was packaged without being attached to the tube, even though it was inconvenient.

The present invention has been made to solve the above-mentioned problems. That is, an object of the present invention is to provide a clamp that does not cause bending of the tube even when it is attached to the tube and packaged.

As mentioned above, the clamp of the present invention has depressions in opposite directions to the plate surface on both sides of the opening that accommodates the elastic tube without blocking it, so that the elastic tube can be bent parallel to the plate surface. The tube can be stored without bending, and even if pressure is applied, the tube will not bend at the clamp portion.

The clamp of the present invention will be described in more detail below with reference to the drawings. Fig. 2 is a perspective view of an example of the clamp of the present invention, Fig. 3 is a plan view, Fig. 4 is a side view, and Fig. 5 is a cross section taken along line A-A in Fig. 3. It is a diagram. Reference numeral 1 denotes a clamp body, which is made of a rigid plate-like member such as various plastic materials. Reference numeral 2 denotes an opening that accommodates the tube without blocking it, and has enough space to accommodate the tube vertically in the clamp body without blocking it. 3 is a squeeze part for closing the tube, and when the tube is pushed into this part, the tube is crushed and closed. 4 and 4' are depressions provided on both sides of the opening, which is the most distinctive feature of the present invention. 4 and 4' are provided in opposite directions with respect to the plate surface of the clamp, and have sufficient space to accommodate the tube parallel to the plate surface without bending. As shown in the drawings, 4 and 4' are semi-cylindrical spaces partitioned by semi-cylindrical walls preferably having an inner diameter approximately equal to the outer diameter of the tube. FIG. 6 is a perspective view showing a state in which the tube 5 is housed in parallel to the clamp body, and FIG. 7 is a perspective view showing a state in which the tube is sandwiched between the clamping portions and closed. As can be seen from Figures 6 and 7, when the clamp of the present invention is not in use, the tube can be stored parallel to the plate surface of the clamp without being blocked, and when the tube is closed, the clamp can be moved 90 degrees. It can be easily occluded by turning it to make it perpendicular to the tube and inserting it into the squeeze part. Therefore, even if the tube is passed through the clamp and packaged, the tube will not bend. Here, 4 and 4' are semi-cylindrical with a diameter slightly smaller than the outer diameter of the tube,
If the width l of the inlet entrance shown in Figure 2 is made slightly smaller than the outside diameter of the tube by making the cross section a shape that is a little closer to a circle than a semicircle, the tube can be easily opened by pressing the tube into the indentation. Since the tube can be fixed in the state shown in FIG. 6, there is no risk that the tube will be bent out of position at 4, 4' during packaging, and it can be conveniently removed during use. Further, the clamp of the present invention may have a shape in which the clamping portion gradually narrows as shown in Fig. 3, or may have a constant width as shown in Fig. 8. .

As described above, the clamp of the present invention can be used for packaging without bending the tube, making it ideal for use in infusions, blood transfusions, blood sampling,
It is useful as a clamp for various circuits used in urine collection, dialysis, etc.
