Problems solved by technology

[0007] However, such a syringe with an adapter, as shown in FIG. 42, has a problem that the lock nut becomes an obstacle to the above-mentioned direct connection type port, and the suction part cannot be connected to the port.
[0008] And as another problem, as shown in FIG. 43, with respect to the syringe with the above-mentioned adapter, when the needle hub is installed on the suction part, the lock nut will become an obstacle, and the user cannot correctly grasp the correct alignment between the suction part and the needle hub. The positional relationship between the suction part and the needle seat cannot be well connected
In addition, since the lock nut is provided on the suction part, the length of the suction part exposed to the outside is insufficient, and there is a problem that the hub cannot be sufficiently held on the suction part.
[0009] In this way, the technical problem of the versatility of the syringe with the lock nut is that it is desired to improve the

Embodiment 1

[0129] The circular hole in Embodiment 1 is a circular loosening hole and a locking hole, and adopts a pattern shape that communicates with each other through a passage, but the present invention can be other embodiments shown below.

Embodiment 2

[0131] In the circular hole 3020a of the lock nut 30A of the second embodiment shown in FIG. 6, the loosening insertion hole 3021a and the engaging hole 3022a overlap each other, and the overlapped portion of the periphery of each hole forms a passage 323a.

[0132] In the present invention, even the circular holes 3020a having such a pattern shape can achieve the same effect as that of the first embodiment. In addition, because the channel 303a of the second embodiment is the overlapped part of the loose insertion hole 3021a and the engaging hole 3022a, it is slightly sharper than that of the first embodiment. With this shape, the engaging hole 3022 can be used to securely engage the suction part 120. combine.

Embodiment 3

[0134] The circular hole 3020b in the lock nut 30B of the third embodiment shown in FIG. 7 is an engaging hole 3022b formed between two loosening insertion holes 3021bA and 3021bB. The loose insertion holes 3021bA, 3021bB and the engaging hole 3022b are formed in such a shape that the circles of the holes overlap with each other, but the holes can be communicated with each other by a passage. In addition, the size and shape of the loosening insertion holes 3021bA and 3021bB do not have to be the same as each other, but at least the stepped portion 123 of the suction portion 120 must be of a size that can be loosely inserted.

[0135] With the circular hole 3020b having such a configuration, the suction part 120 can be moved from the engaging hole 3022b to any one of the two loose insertion holes 3021bA, 3021bB during use, so that the lock nut 30 can be easily attached and disassembled. The burden on the user's operation can be reduced. In particular, based on the treatment me...

Abstract

PROBLEM TO BE SOLVED: To provide a syringe exhibiting a high operability in both cases of using and non-using a lock nut, the lock nut for use in the syringe and the syringe mountable the lock nut. ŽSOLUTION: The prefilled syringe 1 is axially mounted with the lock nut 30, or a connector easily attached / detached to the syringe side, to be engaged with a fixing implement 20 disposed in a step part 123 of a lure part 120 along an axial direction. The fixing implement 20 is provided with a plate-shaped fixing implement body 201 having an inserting hole 202, two plate-shaped arms 205 and 206 extended in one direction from the circumferential face of the fixing implement body 201 and two plate-shaped levers 203 and 204 extended inversely to the one direction from the circumferential face of the fixing implement body 201. When the levers 203 and 204 are pushed, the arms 205 and 206 are opened from the axial direction to detach the lock nut 30. Ž

Description

technical field [0001] The present invention relates to a syringe with an adapter, the adapter for the syringe, and the syringe. Background technique [0002] In the medical field, a syringe as a so-called syringe can be used in various ways. [0003] For example, it is commonly used to attach a female taper adapter such as a needle hub with a needle tube to the suction portion at the front end of the syringe to collect blood from a patient or inject medicine stored in the syringe to the patient. [0004] In addition, syringes are also used in systems such as pipeline systems such as infusion line systems and blood collection tube systems. In this system, the syringe is connected to an external port of the line system, from where the drug is injected into the syringe or otherwise withdrawn from the transfer line. As a method of connecting such a syringe and the pipeline system, a direct connection method (also called a suction slide method) of directly inserting the suctio...
