Abstract
The utility model discloses a syringe connector. The syringe connector comprises a connecting piece, wherein an annular step for accommodating a seal plug is arranged in the middle part of the inner bore wall of the connecting piece; a thread is formed in the outer wall, corresponding to the annular step, of the middle part of the connecting piece; the inner thread of an externally sleeved locking ring is in rotating fit with the thread in the outer wall; an empty groove is formed in the bore wall at one side of the connecting piece; a locking buckle of which one end is fixed on the bore wall, and the other end can move freely is arranged in the empty groove. According to the syringe connector, two syringes can be connected by the connector, liquid outlets of the syringes can be correspondingly attached, sealed and locked, and liquid agents cannot easily overflow, so that the operation efficiency can be improved, and the operation time can be shortened.
Description
Technical field
The utility model relates to a kind of medical device, especially relates to a kind of syringe connector.
Background technology
In medical experimentation, when several different liquors carry out mixed preparing, because chemical reaction occurs liquor after mixing, the denseness of liquid is increased, adopt and conventional grasp method that bottle waves and be difficult to make liquor to reach to mix, liquor is uniformly mixed, and experimenter adopts the method that two syringes are injected mutually to carry out mix and blend; Adopt rubber hose to interconnect the fluid hole of two syringes, repeatedly the liquor in syringe is injected back and forth, several liquors in syringe are uniformly mixed.This mode of operation speed is slow, comes off as easily made because of carelessness rubber hose expand, and causes liquor to overflow.
Summary of the invention
The purpose of this utility model is for existing deficiency, provides one to be connected firmly, and is difficult for the syringe connector that liquor is overflowed.
In order to solve the technical scheme that above-mentioned technical problem adopts be: a kind of syringe connector, comprise connector, described connector inner hole wall middle part is provided with the ring-shaped step of placing sealing skin plug, the middle part lateral wall corresponding with it is provided with screw thread, the internal thread of the retaining ring of outer socket coordinates with lateral wall threads turn, on the hole wall of this connector one side, be provided with the groove of leaving a blank, in the groove of leaving a blank, be provided with one end and hole wall be fixedly linked the other end can be freely movable tab.
Described tab can free movable end thickness be greater than the thickness of connector hole wall, its inner side is provided with latch.
Described connector hole wall is provided with one or more tab.
The utility model beneficial effect is, two syringes adopt connectors to connect, and makes the liquid outlet correspondence of syringe be affixed the tight lock of sealing, and liquor is difficult for overflowing, and has improved operating efficiency, has shortened the operating time.

Fig. 2 is the structural representation of the utility model tab.
Fig. 3 is the schematic diagram that the utility model tab is blocked syringe.
Fig. 4 is the schematic diagram that the utility model connector connects.
Below in conjunction with drawings and Examples, the utility model will be further described.
Detailed description of the invention
As shown in Figure 1, 2, 3, a kind of syringe connector, comprise connector 1, described connector 1 inner hole wall middle part is provided with a ring-shaped step 11, sealing skin plug 3 tops are pressed on ring-shaped step, are provided with screw thread 12 being positioned on the middle part lateral wall that ring-shaped step is corresponding, and internal thread 21 and the lateral wall screw thread 12 of the retaining ring 2 of outer socket are rotatably assorted, on the hole wall 14 of these connector 1 one sides, be provided with the groove 13 of leaving a blank, in the groove of leaving a blank, be provided with one end and be fixedly connected with the tab 4 that the other end can be freely movable with hole wall 14.Tab 4 can free movable end 41 thickness be greater than the thickness of connector hole wall 14, the inner side of tab 4 is provided with latch 42.Connector hole wall 14 is provided with one or more tab 4, is generally provided with three tab for (as Fig. 2) well, makes the tube wall of the fluid hole of syringe 6 obtain secure lock, and the liquid outlet of two syringes is tightly connected.
As Fig. 3,4, when use, liquid outlet 51 ends of one syringe 5 are inserted in sealing skin plug 3 tops of one end of connector, liquid outlet 61 ends of another syringe 6 are inserted in the other end of connector, top and sealing skin plug 3 are fitted tightly, rotation lock ring 2 is to the free movable end 41 direction displacements of tab 4, the free movable end 41 of tab 4 is inwardly withheld, the latch 42 of tab inner side blocks on the tube wall of syringe fluid hole 62, make the liquid outlet docking of two syringes closely be affixed and tightly be locked, liquor cannot overflow.
