Description

  The present invention relates to a medical clamp device that can clamp (close) a drug solution flowing in a tube as necessary.

  As shown in FIG. 7, the conventional medical clamp device includes an inclined plate 73 extending obliquely upward from one end side in the length direction of the bottom portion 71 that is substantially rectangular, and the other end of the bottom portion 71. A standing plate 74 raised from the side through a curved portion 72 ′, and a front end 73 ′ of the inclined plate 73 is pushed down to a locking portion 75 following the steeply inclined portion 74 ′ on the upper inner surface of the standing plate 74. When stopping, the tube K that has passed through the openings 76 and 76 ′ provided in the bending portion 72 on the inclined plate 73 side and the bending portion 72 ′ on the standing plate 74 side is connected to the inclined plate 73. It can be clamped by protrusions 77 and 78 provided on the surface facing the bottom 71. For example, by applying it in the middle of the tube connecting the Bayer bottle and the patient, the chemical solution passing through the tube can be closed or opened at the appropriate time.

  However, if the tube K may escape to the left or right when the tip 73 ′ of the inclined plate 73 is pushed down and locked to the locking portion 75 provided on the inner surface of the standing plate 74, the projections 77 and 78 cause There is a possibility that the tube K cannot be clamped correctly.

In order to solve this problem, several techniques have been disclosed so far. One representative example is Utility Model Registration No. 3116046. This is provided with a horseshoe-like tube holding portion in the vicinity of a protrusion provided on the bottom, so that the tube can be correctly clamped by the upper and lower protrusions without escaping. Moreover, there is JP-A-2005-27721 as two typical ones. This is provided with side walls that oppose both edges in the width direction of the bottom part, and the side walls prevent the tube from escaping from side to side.

  However, both Patent Documents 1 and 2 are excellent in that the tube is difficult to escape to the left and right, but as can be seen from FIG. 7, the engagement provided on the tip of the inclined plate and the inner surface of the standing plate are mutually engaged. Since the distance H to the stopper is wide, the inclined plate itself tends to roll when the tip of the inclined plate and the engaging portion of the upright plate are locked, and the protrusion provided on the lower surface of the inclined plate is the upper surface of the tube. Therefore, the tube cannot be properly clamped, and there is a possibility that the chemical liquid flowing through the tube cannot be reliably closed.

  The present invention is to solve the above-mentioned problems, and the object of the present invention is to temporarily fix the inclined plate and the side walls on both edges of the bottom plate so as to reduce the distance between the two, and the inclined plate itself. To provide a medical clamp that eliminates rolling and can correctly hold a tube without causing a protrusion to slide sideways when the tip of the inclined plate and the engaging portion provided on the inner surface of the upright plate are engaged. is there.

  In order to achieve the above object, a medical clamp device according to the present invention includes an inclined plate extending obliquely upward from one end side in the length direction of a bottom portion, which is substantially rectangular, via a curved portion, and the other end of the bottom portion. An inclined plate that rises from the side through a curved portion, and when the tip of the inclined plate is pushed down and locked to a locking portion that follows the steeply inclined portion of the upper inner surface of the vertical plate, the inclined plate Side clamping part and a tube clamped through an opening provided in the standing board side bending part, respectively, can be clamped by projections provided respectively on the opposing surfaces of the inclined plate and the bottom part In the above, characterized in that provisional coupling means are provided near the upper edge of the inner surface of the side wall provided on both edges in the width direction of the bottom and the lower edge of the outer surface of the protrusion of the inclined plate, and before clamping the tube, Temporarily fix the tip of the inclined plate and the vertical plate locking part It was configured to kill.

  Further, in the medical clamp device according to claim 2, the temporary coupling means is a protrusion provided near the upper edge of the inner surface of the side wall and a recess provided near the lower edge of the outer surface of the protrusion of the inclined plate. This is characterized in that the recesses are coupled to the protrusions so as to ensure an approaching state between the tip of the inclined plate and the engaging portion of the upright plate.

  Furthermore, in the medical clamp device according to claim 3, the temporary coupling means is located near the lower edge of the outer surface of the projection of the inclined plate and the housing having a lower locking surface provided near the upper edge of the inner surface of the side wall. It is a housing having an upper locking surface provided, and is connected to the housing on the side wall side so that the housing on the inclined plate side is applied from below, and the tip of the inclined plate and the locking portion of the standing plate It was configured to ensure close proximity.

  According to the present invention, the inclined plate and the side walls on both edges of the bottom plate are temporarily fixed to reduce the distance between them and eliminate the rolling of the inclined plate itself, so that the tip of the inclined plate is pushed downward to stand upright. The operation of locking the locking portion while sliding the steeply inclined portion of the plate is stabilized. Therefore, the projection provided on the lower surface of the inclined plate does not slide on the upper surface of the tube, and an excellent effect is obtained that the tube can always be correctly clamped.

  Further, according to the invention according to claim 2, since the concave portion can be coupled to the convex member while being deformed, the front end of the inclined plate and the engaging portion of the upright plate can be secured in an approaching state. There is no rolling when pushing down the tip. Moreover, since the recess escapes downward after the tube is clamped by the projection, it has various excellent effects such as not interfering with the clamp.

  Further, according to the invention of claim 3, since the inclined plate side casing can be securely coupled to the side wall side casing from below, the inclined plate end and the standing plate engaging portion Can be secured in an approaching state, so that the roll does not occur when the tip of the inclined plate is pushed down. Moreover, since the casing on the inclined plate side only hits the casing on the side wall side from the bottom, after the tube is clamped by the projection, it escapes downward so that it does not interfere with the clamping. It is.

  Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of the present clamping tool, FIG. 2 is an operation view of the temporary fixing means, (a) before temporary fixing, (b) at the time of temporary fixing, and FIG. 3 at the time of temporary fixing of the protrusion and the recess. 4 is a cross-sectional view when the tube is clamped, FIG. 5 is a cross-sectional view when the housing is temporarily fixed, and FIG. 6 is a cross-sectional view when the tube is clamped.

  Reference numeral 1 is a clamp device of the present application, and 2 is a bottom portion having a substantially rectangular shape. An inclined plate 4 extending obliquely upward from one end side in the length direction of the bottom portion 2 via the curved portion 3 and a standing plate 5 raised from the other end side of the bottom portion 2 via the curved portion 3 ′. Provided on the upper inner surface of the upright plate 5 is a locking portion 6 following the steeply inclined portion 5 '.

  Openings 7 and 7 ′ are provided in the bending portion 3 on the inclined plate 4 side and the bending portion 3 ′ on the standing plate 5 side, and a tube K is passed through the holes 7 and 7 ′. Protrusions 8 and 9 are provided on the opposing surfaces of the inclined plate 4 and the bottom portion 2, respectively, and the protrusions 8 and 9 push the tip 4 ′ of the inclined plate 4 downward to engage the locking portion 6 of the standing plate 5. The tube K can be clamped from above and below when locked to.

  Two side walls 10 are provided opposite to each other at both edges in the width direction of the bottom portion 2. A protrusion 11 is provided near the upper edge of each inner surface of the side walls 10, while a recess 12 is provided near the lower edge of the outer surface of the protrusion 8 of the inclined plate 4. In this case, the convex 11 and the recess 12 constitute a temporary coupling means 13.

  The temporary coupling means 13 has a distance H between the tip 4 ′ of the inclined plate 4 and the engaging portion 6 of the upright plate 5 before the temporary coupling between the convex 11 and the recess 12 as shown in FIG. As you can see, it's wide open. On the other hand, after provisional coupling, the distance H ′ between the tip 4 ′ of the inclined plate 4 and the locking portion 6 of the upright plate 5 is narrowed as shown in FIG. The process in which the recess 12 provided near the lower edge of the outer surface of the projection 8 of the inclined plate 4 temporarily engages with the convex 11 provided near the upper edge of the inner surface of the side wall 10 is performed by pressing the tip 4 ′ of the inclined plate 4. The lower edge of the recess 12 is fitted to the lower surface of the protrusion 11 while being deformed by the elasticity of the material by pressing with the finger until the recess 12 hits the protrusion 11 and continuing to press it.

  In the state where the convex 11 and the recess 12 are temporarily joined, as shown in FIG. 3, the distance between the tip 4 ′ of the inclined plate 4 and the engaging portion 6 of the standing plate 5 can be made closer. When the upper and lower surfaces of the tube K are sandwiched between the protrusion 8 of the inclined plate 4 and the protrusion 9 of the bottom plate 2 without lateral shaking, the upper surface of the tube K is correctly sandwiched without sliding. At the time of this clamping, as shown in FIG. 4, the recess 12 fitted on the lower surface of the protrusion 11 moves downward, so that it does not interfere with the clamping.

  The temporary coupling means 13 has a casing 14 having a lower locking surface provided near the upper edge of the inner surface of the side wall 10 and a hook having an upper locking surface provided near the outer edge of the protrusion 9 of the inclined plate 4. It may be composed of the body 15. That is, when the inclined plate 4 is pushed downward, the inclined surfaces of the housing 15 slide over the inclined surfaces of the housing 14 and push the side walls 10 outward to get over the inclined surfaces and temporarily engage each other as shown in FIG. It becomes.

  In the state where the housing 14 and the housing 15 are temporarily coupled, the distance between the tip 4 ′ of the inclined plate 4 and the engaging portion 6 of the standing plate 5 is narrow. When the front end 4 ′ of 4 is pushed and locked to the locking portion 6 of the upright plate 5, the tube K is correctly held by the protrusions 8 and 9 without sliding. At the time of this clamping, as shown in FIG. 6, the housing 15 on the projection 9 side of the inclined plate 4 is engaged with the lower surface of the housing 14 on the side wall 10 and moves downward, so that it does not interfere with the clamping. .

  Next, the operation of the present clamping tool 1 will be described. First, for example, a tube K connecting a Bayer bottle and a patient is passed through the openings 7 and 7 ′ provided in the curved portions 3 and 3 ′ of the clamp device 1 of the present application in advance. Next, a recess 12 (or a housing 15 having an upper locking surface) provided near the lower outer edge of the protrusion 8 of the inclined plate 4 and a protrusion 11 (or closer to the inner upper edge of the side wall 10) (or The housing 14) having the lower locking surface is temporarily engaged. This temporary engagement not only eliminates the rolling of the inclined plate itself, but also brings the distance between the tip of the inclined plate and the engaging portion provided on the inner surface of the upright plate so that the tube K is correctly clamped.

  As described above, in the temporarily coupled state, the tip 4 ′ of the inclined plate 4 is pushed down against the elasticity of the curved portion 3 and can be pushed easily when locked to the locking portion 6 of the standing plate 5. The chemical liquid flowing in the tube K connecting the Bayer bottle and the patient can be reliably controlled.

  The clamp device 1 of the present application is capable of holding and closing the chemical solution flowing through the tube as necessary, so that it has high industrial applicability in the medical industry and others.
