Abstract
The invention provides a matching structure for a perfusion tube connector and a perfusion tube connector lengthener, and belongs to the field of medical appliances. The matching structure comprises a connector body and a lengthening connector, wherein a step ring is formed on the outer wall of one end of the connector body. The matching structure is characterized in that the spacing step ring and an adaptor are formed on the outer wall of one end, facing the lengthening connector, of the connector body, the adaptor is positioned on the end face part of one end, facing the lengthening connector, of the connector body, and an adaptive external thread is arranged on the outer wall of the adaptor; the strengthening connector comprises a connecting sleeve and a fixed ring; the center of one end, facing the connector body, of the connecting sleeve is narrowed to form a conical insert tube; a blocking ring is formed on the outer wall of the conical insert tube; the fixed ring is sleeved on the conical insert tube; a retainer ring is formed on the inner wall of the fixed ring, is positioned in the middle part of the lengthwise direction of the fixed ring, and is limited by the blocking ring; an adaptive internal thread is arranged on the inner wall of one end, facing the adaptor, of the fixed ring, and is matched with the adaptive external thread. According to the matching structure, the requirement for lengthening the length of a perfusion tube is fulfilled.
Description
Technical field
The invention belongs to the medical devices technical field, be specifically related to the combinative structure of a kind of tube for transfusion joint and tube for transfusion joint lengthening device
Background technology
tube for transfusion joint is used to connect the tube for transfusion of transfusion device, that is to say and the tube for transfusion joint is the transition member between the injection drain pipe of drain pipe on transfusion device such as the transfusion bag and syringe.The structure of the tube for transfusion joint in the prior art comprises a joint body 1 by shown in Figure 2, and the outer wall of this joint body 1 constitutes a plurality of by little and big step circle 11, uses easily connecting with drain pipe.But in clinical care and home care, can run into the situation of tube for transfusion limited length usually, present disposal way be with the residing position of patient towards the direction of tube for transfusion near or tube for transfusion is moved to residing position of patient such as sick bed place as much as possible.Yet all there is the probability that receives the environmental condition restriction inevitably in any one mode in aforesaid two kinds of disposal options.
In view of above-mentioned; Be necessary the structure of the tube for transfusion joint in the prior art is improved, and be the supporting corresponding lengthening device of tube for transfusion joint (lengthening joint) after improving, for this reason; The applicant has done useful design, and the technical scheme that will introduce below produces under this background
Summary of the invention
task of the present invention is to provide a kind of and helps avoid tube for transfusion self limited length and influence to use to satisfy for patient's transfusion tube for transfusion is realized artificial the extend combinative structure of device of the tube for transfusion joint that requires and tube for transfusion joint that prolongs.
task of the present invention is accomplished like this; The combinative structure of a kind of tube for transfusion joint and tube for transfusion joint lengthening device; Comprise a joint body and one and the lengthening joint that connects of joint body; Constitute a plurality of on the outer wall of one end of joint body by little and big step circle; Be characterised in that: said joint body constitutes a limited step circle and a connector on the outer wall of an end of lengthening joint, and wherein: connector is positioned at the end face area of joint body towards an end of lengthening joint, and on the outer wall of connector, is provided with and connects external screw thread; Described lengthening joint comprises that one has the adapter sleeve and a ring for fixing of insertion hole; Adapter sleeve contracts towards the central narrow of an end of joint body and constitutes one and be used for the tapered plugging pipe of pegging graft and cooperating with the liquid-through hole of joint body; And on the outer wall of this tapered plugging pipe, constitute the protruding circle of a retaining; Ring for fixing movably is nested with on said tapered plugging pipe, on the inwall of this ring for fixing and the middle part that occupy the length direction of ring for fixing constitute a back-up ring, this back-up ring is spacing by the protruding circle of described retaining; And be provided with on the inwall of an end of said connector at ring for fixing and connect female thread, this connects female thread and matches with the described external screw thread that connects.
technical scheme provided by the invention can with the ring for fixing of lengthening joint through its connect on the connector of female thread and joint body to connect external screw thread matched; And liquid-through hole inserting with tapered plugging pipe and joint body; Thereby when self length of tube for transfusion is restricted; As long as corresponding pipe is inserted insertion hole, thereby can satisfy the requirement that prolongs tube for transfusion length.
Description of drawings
Fig. 1 is the embodiments of the invention structure chart.
Fig. 2 is the structure chart of the joint body in the prior art.
The specific embodiment
see also Fig. 1; Provided a joint body 1; The lower end of this joint body 1 (is example with the shown position state) constitute the casing coupling formula by big and little step circle 11, use and make tube for transfusion and step circle 11 insertings (belonging to known technology) easily.Joint body 1 promptly constitutes a limited step circle 12 and a connector 13 towards an end of illustrated lengthening joint 2 towards a last end; Wherein: connector 13 is formed in the end face area of joint body 1 towards an end of lengthening joint 2, and on the outer wall of this connector 13, is designed with and connects external screw thread 131.According to common practise, the axial central authorities of joint body 1 are that the central authorities of short transverse have a liquid-through hole 14.
please continue referring to Fig. 1; The lengthening joint of having mentioned above 2 comprises an adapter sleeve 21 and a ring for fixing 22; Adapter sleeve 21 has an insertion hole 212, and the tube for transfusion that supplies to be used to extend (also or claim extension pipe) inserts, and adapter sleeve 21 has shortened a tapered plugging pipe 211 into towards the end end face central authorities window of joint body 1; Liquid-through hole 14 insertings of the end of this tapered plugging pipe 211 and joint body 1, thus the tube chamber of tapered plugging pipe 211 is communicated with liquid-through hole 14.On the outer wall of tapered plugging pipe 211 and around the circumferencial direction of tapered plugging pipe 211, constitute the protruding circle 2111 of a retaining.Ring for fixing 22 is nested with on tapered plugging pipe 211; On the inwall of this ring for fixing 22 and the middle position that is positioned at the short transverse of ring for fixing 22 substantially constitute a back-up ring 221 around the circumferencial direction of inwall; This back-up ring 221 matches with the protruding circle 2111 of aforesaid retaining, and is promptly spacing to it by retaining protruding circle 2111.Again; Ring for fixing 22 towards promptly be positioned on the inwall of an end of aforementioned connector 13 the protruding circle 2111 of retaining below inwall on constitute and connect female thread 222; Connect female thread 222 by this and match, thereby lengthening joint 2 of the present invention is connected with joint body 1 with the aforesaid external screw thread 131 that connects.During use, as long as extension pipe is promptly remained the tube for transfusion and insertion hole 212 insertings that continue
