Syringe holder for balloon catheter and syringe set for balloon catheter

Abstract

A syringe holder which is capable of holding a plurality of types of syringes used for expanding a balloon catheter so as to be capable of being detached and attached. Preferably, a clearance is provided between the syringe holder and the syringe, so that gas can adequately contact syringes during a sterilizing treatment. The syringe holder is formed, for example, by forming a plurality of grooves which are similar to the shape of the syringe and slightly larger than the syringe on a sheet formed of resilient material. Preferably, the shape is formed to prevent dropping off of the syringe from the syringe holder.

1 . A syringe holder for a balloon catheter comprising; 
 a plurality of holding parts for holding syringes to be connected to the balloon catheter, in a manner whereby the syringes are individually attachable and detachable.    
   
   
       2 . The syringe holder for a balloon catheter according to  claim 1 , wherein the holding parts are formed to provide an allowance with respect to a surface contour of a corresponding syringe, a respectable inner surface of each holding part including at least one protrusion.  
   
   
       3 . The syringe holder for a balloon catheter according to  claim 1 , wherein the holding parts have a non-circular cross-section which is substantially orthogonal to the direction of a length thereof.  
   
   
       4 . The syringe holder for a balloon catheter according to  claim 1 , wherein sizes of the plurality of holding parts are not the same, and are adapted to be capable of accommodating syringes of different outer diameters.  
   
   
       5 . The syringe holder for a balloon catheter according to  claim 1 , wherein the holding parts are formed with a flat portion for constraining rotation of a syringe coming into abutment with a flange of the syringe.  
   
   
       6 . The syringe holder for a balloon catheter according to  claim 1 , wherein the holding parts are formed with an opening for allowing a distal portion on a side of a connecting portion for connecting a syringe with the balloon catheter to project therefrom.  
   
   
       7 . The syringe holder for a balloon catheter according to  claim 1 , wherein the holding parts include a storage groove, the storage groove including an opening for inserting a syringe.  
   
   
       8 . The syringe holder for a balloon catheter according to  claim 7 , wherein the storage groove includes a projection at an upper portion thereof for preventing a stored syringe from dropping off.  
   
   
       9 . The syringe holder for a balloon catheter according to  claim 8 , wherein the syringe holder is resilient, so when a syringe is inserted therein, the opening is widened by resilient deformation.  
   
   
       10 . The syringe holder for a balloon catheter according to  claim 7 , wherein the storage groove comprises at least a cylinder storage groove for storing a cylinder of the syringe, a flange storage groove for storing the flange of the syringe, and a plunger storage groove for storing a plunger of the syringe in communication with each other.  
   
   
       11 . The syringe holder for a balloon catheter according to  claim 10 , wherein the cylinder storage groove has a size smaller than the flange of the syringe so that the cylinder of the syringe is prevented from moving in an axial direction and dropping off.  
   
   
       12 . The syringe holder for a balloon catheter according to  claim 10 , wherein the plunger storage groove is closed on one end surface so as to prevent the plunger of the syringe from coming apart from the cylinder and dropping off.  
   
   
       13 . The syringe holder for a balloon catheter according to  claim 7 , wherein the storage groove constrains rotation of the syringe in a circumferential direction.  
   
   
       14 . The syringe holder of  claim 1 , in combination with at least one syringe stored in a corresponding holding part of the syringe holder, to form a syringe set for a balloon catheter.  
   
   
       15 . The syringe holder of  claim 1 , wherein the syringe set includes a balloon catheter.  
   
   
       16 . The syringe holder of  claim 14 , wherein the syringe set is enclosed in a sterilized package.  
   
   
       17 . The syringe holder of  claim 16 , wherein the syringe set is enclosed in a single sterilized package.
