Abstract
This utility model belongs to technical field of medical instruments, be specifically related to a kind of drainage tube connection special three-way, the two ends that axial line in threeway is identical are respectively the cone-shaped interface that square interface and outer bore are greater than interior bore, between square interface and cone-shaped interface, and the port vertical with axial line is upper interface; Described threeway central outer surface connection is provided with water conservancy diversion knob; The inner surface of cone-shaped interface and square interface posts soft rubber, the Packed soft rubber of plug in upper interface.Advantage: adopt three-port structure secure connection drainage bag, drainage tube and needle tubing, cost is lower, and convenient and practical, is suitable for promoting.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of drainage tube connection special three-way.
Background technology
The union joint of common drainage bag is the taper joint that outer bore is less than interior bore, cannot directly dock with common drainage tube, as being connected with drainage tube head end, and often need clinically to carry out injection to patient, at this moment, cannot injection be carried out by general connection mechanism, connecting device is complicated, and not special, easily cause drainage bag or drainage tube to come off, and cause pathogen contamination.
The existing documents patent No. 201320772429.3 three-way interface of drainage tube (after the connecting medical thoracoscopy) it is disclosed that a kind ofly can carry out the three-way interface of drainage tube after the connection medical thoracoscopy be connected with the drainage tube after medical thoracoscopy, but, disclosed taper joint is exclusively used in docking drainage bottle, for collar extension is less than the taper joint of internal orifice, functional specification face is narrow, should not promote the use of.
Utility model content
This utility model, according to the deficiencies in the prior art, proposes simple, the functional drainage tube connection special three-way that can directly be connected with drainage pack adapter by force of a kind of structure.
The technical solution of the utility model is as follows: a kind of drainage tube connection special three-way, the two ends that axial line in threeway is identical are respectively the cone-shaped interface that square interface and outer bore are greater than interior bore, between square interface and cone-shaped interface, and the port vertical with axial line is upper interface; Described threeway central outer surface connection is provided with water conservancy diversion knob; The inner surface of cone-shaped interface and square interface posts soft rubber, the Packed soft rubber of plug in upper interface.
Preferably screw thread is provided with in the soft rubber inner surface of cone-shaped interface and square interface.
Wherein, cone-shaped interface connection corresponding with drainage pack adapter, square interface is corresponding with drainage tube joint to be connected, upper interface is the soft rubber of sealing, when in needs injection to drainage tube or when rinsing drainage tube, needle tubing is penetrated upper interface, direct injection, and control the medicinal liquid flow direction by water conservancy diversion knob.
Advantage of the present utility model: adopt three-port structure secure connection drainage bag, drainage tube and needle tubing, cost is lower, and convenient and practical, is suitable for promoting.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, upper interface, 2, square interface, 3, cone-shaped interface, 4, drainage tube joint, 5, drainage pack adapter, 6, water conservancy diversion knob.
Detailed description of the invention
Composition graphs 1 pair of the present embodiment is described in detail, but this utility model is not limited to specific embodiment.
Embodiment 1
A kind of drainage tube connection special three-way, the two ends that the axial line in threeway is identical are respectively the cone-shaped interface 3 that square interface 2 and outer bore are greater than interior bore, and between square interface 2 and cone-shaped interface 3, and the port vertical with axial line is upper interface 1; Described threeway central outer surface connection is provided with water conservancy diversion knob 6; The inner surface of cone-shaped interface 3 and square interface 2 posts soft rubber, the Packed soft rubber of plug in upper interface 1.
Preferably screw thread is provided with in the soft rubber inner surface of cone-shaped interface 3 and square interface 2.
Wherein, cone-shaped interface 3 connection corresponding with drainage pack adapter 5, square interface 2 is corresponding with drainage tube joint 4 to be connected, upper interface 1 is the soft rubber of sealing, when in needs injection to drainage tube or when rinsing drainage tube, needle tubing is penetrated upper interface 1, direct injection, and control the medicinal liquid flow direction by water conservancy diversion knob 6.
Above-described is only preferred implementation of the present utility model, should be understood that for a person skilled in the art, under the prerequisite not departing from this utility model structure, can also make some distortion and improvement, these all can not affect effect and the practical applicability of this utility model enforcement.
