Problems solved by technology

In addition, in the absence of the hydrophobic filter 950, even if the normal operation is performed, the solution or the drug solution may pass through the second hole 932 and the second flow path 942 between the drug solution bag and the vial 980. and gas flow path 923 (i.e., not passing through syringe 990) to flow
These make the preparation of the desired medicinal solution difficult

Embodiment approach 1

[0092] figure 1 It is a perspective view showing an example of a state of use of the medical connector (hereinafter simply referred to as "connector") 1 according to Embodiment 1 of the present invention. The connector 1 according to Embodiment 1 includes a first connector 100 connected to a drug solution bag (first container) 60, a second connector 200 connected to a vial (second container) 80, and a second connector 200 arranged on the first The tubular portion 30 between the connector 100 and the second connector 200 , and the cock 40 inserted into one end of the tubular portion 30 . The other end of the tubular portion 30 is connected to a syringe 90 via a flexible tube 99 . The syringe 90 includes an outer cylinder 91 and a plunger 92 inserted into the outer cylinder 91 to be pushed and pulled. A dome-shaped air sending member 410 is attached to an end of the cock 40 opposite to the tubular portion 30 .

[0093] The drug solution bag 60 is a pouch formed by laminating...

Embodiment approach 2

[0213] In the above Embodiment 1, as in Figure 30 As described in , by applying the thrust F to the air-feeding member 410 to crush the air-feeding member 410 , the dissolving solution 68 in the male port 110 and the bag-side space 32 is discharged into the drug solution bag 60 . However, after the air delivery member 410 is crushed, the solution 68 may remain in the male port 110 and / or the bag side space 32 , and the ventilation of the hydrophobic filter 50 may not be restored. In this case, it is still difficult to pull the plunger 92 of the syringe 90 . In addition, after the air delivery member 410 is crushed, air cannot flow from the drug solution bag 60 into the inner cavity 415 of the air delivery member 410, so the air delivery member 410 cannot elastically return to its original shape. Therefore, it becomes difficult to crush the air sending member 410 by repeatedly applying the thrust F, and to send air to the bag-side space 32 . In this way, in Embodiment 1, whe...

Abstract

A first male member (110) and a tubular portion (30) are in communication via first to third holes (21 to 23). A liquid channel (211) and a gas channel (212) of the second male member (210) are in communication with the tubular portion. First to third channels (41 to 43) are formed in a stopcock (40). The stopcock can switch between a first rotation position at which the first channel puts the first hole and a syringe connection portion (32) of the tubular portion in communication, and a second rotation position at which the first channel puts the liquid channel and the syringe connection portion in communication. When the stopcock is at the second rotation position, the second hole and the gas channel are in communication via the second channel, and the first male member and an inner cavity (45) of the stopcock are in communication via the third hole and the third channel. A first hydrophobic filter (50a) is provided in the channel that connects the first male member and the gas channel when the stopcock is at the second rotation position, and a second hydrophobic filter (50b) is provided in the channel that connects the first male member and the air supplying member (410) that is connected to the stopcock when the stopcock is at the second rotation position.

Description

technical field [0001] The present invention relates to a medical connector that connects two containers and can be suitably used to transfer a medical solution obtained by dissolving a drug in one container to the other container. Background technique [0002] Typically, the medicament in the vial is in powder form. When administering the medicine to the patient, the dissolving solution is poured into the vial to dissolve the medicine to obtain a medicine solution, and then the medicine solution is transferred to the medicine solution bag. The amount of the liquid medicine to be transferred to the liquid medicine bag must be accurately measured according to the physique of the patient. [0003] In some cases, the drug contained in the vial is a drug designated as a strong drug such as an anticancer drug. It is necessary to avoid situations where the chemical solution containing such a dangerous chemical leaks and adheres to the operator's fingers or the like, or the opera...
