The present application is a continuation of prior application Ser. No. 11/493,192. filed Jul. 26, 2006, by Ryuji NAGAMATSU, entitled SYRINGE HOLDER FOR BALLOON CATHETER AND SYRINGE SET FOR BALLOON CATHETER, which is a divisional of U.S. application Ser. No. 11/128,092 filed May 11, 2005, by Ryuji NAGAMATSU, entitled SYRINGE HOLDER FOR BALLOON CATHETER AND SYRINGE SET FOR BALLOON CATHETER, which claims the benefit of priority from prior Japanese Patent Application No. 2004-143616, filed on May 13, 2004, the entire contents of which is incorporated herein by reference.
The present invention provides a syringe holder for a balloon catheter which can hold a plurality of syringes so as to be capable of being attached and detached.
In this arrangement, the plurality of syringes can be treated together as a single unit. Since the syringes are held so as to be capable of being attached and detached, an operator can take only a required syringe when in use.
The flange storage groove 36 a continues to the cylinder storage groove 35 a, and is larger than the cylinder storage groove 35 a in width. FIG. 4 is a cross-sectional view taken along a cutting line (FIG. 4-FIG. 4) in FIG. 1, showing that no syringe is mounted.
As shown in FIG. 4, a side wall of the flange storage groove 36 a has an inclination being reduced in width toward the bottom, and the bottom has a form of a smooth depression.
FIG. 5 shows a cross-sectional view taken along a cutting line (FIG. 5-FIG. 5) in FIG. 1, showing that no syringe is mounted. As shown in FIG. 5, the depth of the flange storing groove 36 a is deeper than that of the cylinder storage groove 35 a, and a boundary plane between the flange storage groove 36 a and the cylinder storage groove 35 a is formed to have an inclination. In the same manner, a boundary plane between the flange storage groove 36 a and the plunger storage groove 37 a is formed to have an inclination.
The syringe 2 is firstly stored in the holding part 61 of the syringe holder 60.
When the syringe 2 is pushed into the holding part 61 from the upper opening 61 b side so that the flange 12 a of the cylinder 6 is stored in the flange storage groove 36 a, the cylinder 6 is inserted therein so as to widen the distance between the protrusions 66, and is set in the cylinder storage groove 64 a. After the cylinder 6 has passed, the protrusions 66 return to their original position.
The cylinder storage groove 74 a is configured in such a manner that the portion near an upper opening 71 b is protruded so as to be close to each other, so that protrusions 75 a are formed, and the bottom side is formed into an oval shape. The number of contact portions between an inner wall of the cylinder storage groove 74 a and the cylinder 6 are three positions at maximum including one on the bottom side and two on the side of the protrusions 75 a. Each of them is subjected to linear contact. Other portions of the syringe 2 are not in contact with the holding part 71 and clearances are formed.
The cylinder storage groove 74 b of the holding part 72 is larger than the cylinder storage groove 74 a, is provided with protrusions 75 b near an upper opening 72 b, and is oval shape on the bottom side. The cylinder storage groove 74 c of the holding part 73 is larger than the cylinder storage groove 74 b, is provided with protrusions 75 c near an upper opening 73 b, and is oval shape on the bottom side.
1. A syringe set for a balloon catheter at least comprising;
a second syringe having a second capacity to expand the balloon catheter to a size corresponding to the second capacity, the second syringe having a side air outlet hole to define the second capacity, the second capacity being larger than the first capacity, the diameter of the outer circumference of the second syringe being larger than that of the first syringe;
a syringe holder at least having a first holding part to fit to a part of the outer circumference of the first syringe for holding the first syringe in a removable manner and a second holding part to fit to a part of the outer circumference of the second syringe for holding the second syringe in a removable manner.
2. The syringe set for a balloon catheter according to claim 1,
3. The syringe set for a balloon catheter according to claim 1,
