The entire operation does not require repeated injections, mixing and other operations, which can greatly reduce the complexity of the work of medical staff, meet clinical needs, and reduce the chance of contact between the drug solution and the outside world, reducing the possibility of environmental contamination of the drug solution.

[0048] In some embodiments, reference Figure 2 and Figure 3 The first transfer assembly 3 includes an inner conical joint 31 and an inner conical joint protective cap 32. The inner conical joint 31 is detachably connected to the drug delivery catheter 1. The inner conical joint 31 can be matched with the outer conical joint 41 or other external joints to ensure the air tightness of the pipeline and avoid leakage. The outer side of the end of the inner conical joint 31 away from the drug delivery catheter 1 is provided with a thread, which can be used to connect an external joint to improve the connection stability. The inner conical joint protective cap 32 is sleeved on the inner conical joint 31, and a circular ring is fixed on it. The circular ring is convenient for hand-held extraction. The end of the inner conical joint 31 that is to be sleeved with the inner conical joint 31 is provided with a raised ring to improve the sleeve stability, and a plurality of anti-slip rings are also provided on the inner side. The anti-slip ring can increase the friction force to prevent the inner conical joint protective cap 32 from falling off.

[0049] In this embodiment, when it is needed, the inner cone joint 31 is connected to the drug delivery catheter 1, and the inner cone joint protection cap 32 is removed, and then the operation can begin.

[0050] In some embodiments, reference Figure 2 and Figure 3 A circle of first protective sleeve 33 is arranged on the outer side of the inner conical joint 31. The first protective sleeve 33 is fixed in the middle section of the inner conical joint 31 and extends from both sides of the fixed position to form a protective ring around the inner conical joint 31. There is a gap between the protective ring and the inner conical joint 31 for inserting the drug delivery catheter 1 or external equipment. At this time, the first protective sleeve 33 can form a strict protection for it to prevent the connection from being polluted by the environment. In addition, a raised ring is arranged on the outer side of the first protective sleeve 33. The raised ring and the inner conical joint protective cap 32 are mutually clamped, so as to ensure that the inner conical joint protective cap 32 is not easy to fall off when not in use.

[0051] In this embodiment, the first protective cover 33 is made of elastic material, which may be silicone or rubber. When not in use, the outer side of the first protective cover 33 is clamped with the inner side of the inner conical joint protective cap 32, and its surface is in contact with the anti-slip ring inside the inner conical joint protective cap 32, thereby ensuring that the inner conical joint protective cap 32 will not fall off without external pulling, and at the same time, it can also provide protection for the front and rear ends of the inner conical joint 31.

The outer conical joint 41 is sleeved with a drug delivery catheter 1, and the end thereof connected with the drug delivery catheter 1 has a small diameter and the end thereof away from the drug delivery catheter 1 has a large diameter, so that it is easy to insert it into the drug delivery catheter 1; the outer conical joint protective cap 42 is sleeved on the outer conical joint 41 to provide protection for it.

[0055] In this embodiment, the outer conical joint 41 can be matched with the outer inner conical joint 31 to ensure the stability of the connection and the air tightness of the pipeline; a pull ring is fixed on the outer conical joint protective cap 42 to facilitate the removal and installation of the outer conical joint protective cap 42.

[0056] In some embodiments, reference Figures 4 to 7 A circle of second protective sleeve 43 is arranged on the outer side of the outer conical joint 41 away from the end of the drug delivery catheter 1. The second protective sleeve 43 is fixed on the outer conical joint 41. The second protective sleeve 43 is annular. The bottom of the second protective sleeve 43 away from the outer conical joint 41 is hollow, which is convenient for external equipment to connect with the outer conical joint 41. The diameter of the second protective sleeve 43 close to the drug delivery catheter 1 is larger than the diameter of the end away from the drug delivery catheter 1, and the end of the second protective sleeve 43 away from the drug delivery catheter 1 is provided with a convex ring for clamping the outer conical joint protective cap 42. When the outer conical joint protective cap 42 is sleeved, the second protective sleeve 43 abuts against the inner wall of the outer conical joint protective cap 42, and the convex ring is connected to the bottom of the outer conical joint protective cap 42, ensuring that the outer conical joint protective cap 42 will not fall off in the absence of external force. There are multiple protrusions 44, and the multiple protrusions 44 are arranged around the outer conical joint 41. The bottom of the outer conical joint 41 is fixedly connected to the second protective cover 43 near one end of the drug delivery catheter 1. This part can be convenient for the user to grasp and can also ensure that the drug delivery catheter 1 will not be too much on the outer conical joint 41.

[0057] In this embodiment, the second protective cover 43 can provide protection for the outer conical joint 41 to ensure that the external environment will not contaminate the connection during connection.

[0059] In this embodiment, when the puncture device is needed, it is only necessary to remove the puncture device protection cap 52 and insert the puncture device 51 into the medicine bottle.

[0060] In some embodiments, a hand piece 53 is fixed to the puncture device 51. The hand piece 53 is flat, wide at both ends and narrow in the middle, which is convenient for grasping. In order to reduce its own weight, it is hollow.

[0061] In some embodiments, a boss 54 is provided at one end of the puncture device 51 away from the drug delivery catheter 1, and the boss 54 is connected to the puncture device 51. The boss can prevent the puncture device 51 from being inserted too far into the medicine bottle to avoid contamination, and can also prevent the end of the puncture device 51 from being touched.
