Two-end vial and radiopharmaceuticals dispensing and injection system incorporating the two-end vial

Abstract

A two-end vial includes a body with an upper opening at the top and a lower opening at the bottom. The upper opening is sealed with an upper stopper and the lower opening is sealed with a lower stopper, forming a closed chamber for containing a liquid radiopharmaceuticals therein. An air filter means is mounted to the upper stopper. Also, a radiopharmaceuticals supply unit is connected to the upper stopper for supplying the radiopharmaceuticals to the body. The radiopharmaceuticals supply unit may include an inlet tube or a syringe. A radiopharmaceuticals withdrawal unit withdraws the radiopharmaceuticals from the body via the lower stopper. The radiopharmaceuticals withdrawal unit may include an outlet tube or a syringe for drawing the radiopharmaceuticals.

1 . A two-end vial and a radiopharmaceucticals dispensing and injection system incorporating the two-end vial, comprising: 
 a body, which is hollow and formed with an upper opening at the top and a lower opening at the bottom of the body;    an upper stopper, which is mounted to the upper opening of the body for sealing the upper opening;    a lower stopper, which is mounted to the lower opening of the body for sealing the lower opening, and by sealing the body with the upper stopper and the lower stopper, a closed chamber is formed for accommodation of radiopharmaceucticals therein; and    a radiopharmaceuticals withdrawal unit, which is connected to the lower stopper for withdrawing the radiopharmaceucticals from the body.    
   
   
       2 . The two-end vial and radiopharmaceucticals dispensing and injection system incorporating the two-end vial as claimed in  claim 1 , wherein the two-end vial is further connected with a radiopharmaceuticals supply unit which supplies radiopharmaceuticals to the body through the upper stopper.  
   
   
       3 . The two-end vial and radiopharmaceucticals dispensing and injection system incorporating the two-end vial as claimed in  claim 2 , wherein the radiopharmaceuticals supply unit comprises an inlet tube, in which one end of the inlet tube is provided with a needle for inserting to the upper stopper, and the other end of the inlet tube is connected with a radiopharmaceuticals reservoir.  
   
   
       4 . The two-end vial and radiopharmaceuticals dispensing and injection system incorporating the two-end vial as claimed in  claim 1 , wherein the radiopharmaceuticals withdrawal unit comprises an outlet tube, in which one end of the outlet tube is inserted to the lower stopper, and the radiopharmaceuticals is conveyed through the other end.  
   
   
       5 . The two-end vial and radiopharmaceucticals dispensing and injection system incorporating the two-end vial as claimed in  claim 1 , wherein the radiopharmaceuticals withdrawal unit comprises a syringe which includes a needle at the front end for inserting through the lower stopper and drawing the liquid radiopharmaceuticals contained in the body.  
   
   
       6 . The two-end vial and radiopharmaceucticals dispensing and injection system incorporating the two-end vial as claimed in  claim 1 , wherein the upper stopper is further provided with an air filter means which comprises a needle for inserting to the upper stopper.  
   
   
       7 . A two-end vial, comprising: 
 a body, which is hollow and formed with an upper opening at the top and a lower opening at the bottom of the body;    an upper stopper, which is mounted to the upper opening of the body for sealing the upper opening; and    a lower stopper, which is mounted to the lower opening of the body for sealing the lower opening;    wherein by sealing the body with the upper stopper and the lower stopper, a closed chamber is formed for accommodation of radiopharmaceucticals therein.    
   
   
       8 . A two-end vial as claimed in  claim 7 , wherein the body has an annular shape configuration, and the diameter of the body is larger than the diameter of the upper opening and the diameter of the lower opening.  
   
   
       9 . A two-end vial as claimed in  claim 7 , wherein the body is made of transparent material.  
   
   
       10 . A two-end vial as claimed in  claim 7 , wherein the outer wall of the body is provided with graduations for indicating the volume.  
   
   
       11 . A two-end vial as claimed in  claim 7 , wherein the upper opening further comprises a lateral flange.  
   
   
       12 . A two-end vial as claimed in  claim 7 , wherein the lower opening further comprises a lateral flange.  
   
   
       13 . A two-end vial as claimed in  claim 7 , wherein at least one of the openings of the body comprises a regular annular shape configuration.
