Problems solved by technology

[0008] However, such syringes with adapters such as Figure 42 As shown, there is a problem that the lock nut becomes an obstacle to the above-mentioned direct connection type interface, and the suction part cannot be connected to the above-mentioned interface.
[0009] And as other questions like Figure 43 As shown, with respect to the above-mentioned syringe with adapter, when the needle hub is installed on the suction part, the lock nut will become an obstacle, and the user cannot accurately grasp the correct positional relationship between the suction part and the needle hub, and the suction part and the needle hub doesn't connect well
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.
[0010] 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

[0130] 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

[0132] exist Figure 6 In the circular hole 3020a of the locknut 30A of the illustrated embodiment 2, 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.

[0133] 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

[0135] Figure 7 The circular hole 3020b in the lock nut 30B of the illustrated embodiment 3 is an engaging hole 3022b formed between two loosening insertion holes 3021bA, 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.

[0136] 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

The present invention aims at offering: a syringe connectable to a port in a fixed manner as well as capable of demonstrating high operational performance even in the case of direct connection where a connector is not used; a connector used for the syringe; and a syringe able to attach the connector thereto. For the attainment of the above objectives, the medical syringe of the present invention is a medical syringe including a cyrindrical connection supporting member which enhances the holding force of a luer part inserted into a port when the medical syringe is connected to the port. The connection supporting member is set by sliding along the luer or a syringe body in a state of being movable between a first position near a tip of the luer and a second position away from the tip of the luer. The medical syringe is characterized in that , when the connection supporting member is moved to the second position, the tip of the luer part is exposed.

Description

[0001] This application is a divisional application of the application date of February 7, 2005, the application number 200580012078.4, and the invention titled syringe with adapter, adapter for syringe and syringe. technical field [0002] The present invention relates to a syringe with an adapter, the adapter for the syringe, and the syringe. Background technique [0003] In the medical field, a syringe as a so-called syringe can be used in various ways. [0004] 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. [0005] 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 ...
