Abstract
A kind of central venous catheter, it comprises: built-in pipe, holder, connecting hose, clamp, union joint; Built-in pipe, holder, connecting hose, union joint connect in turn, and clamp is arranged in connecting hose, by the slit optionally tube sealing that clamp is offered; Described connecting hose is formed as two sections, and the first end of first paragraph is connected with holder, and the second end of first paragraph forms connecting device; The first end of second segment forms connecting device, and the second end of second segment is connected with union joint, and clamp is arranged on second segment; The connecting device of first paragraph and the connecting device of second segment are removably fixed together.Central venous catheter of the present utility model, by connection tube is designed to two sections, when the second end occurs strain or be damaged, only needs to replace second segment easily, makes patient avoid again carrying out putting pipe operation, has saved medical treatment cost simultaneously.
Description
Technical field
This utility model relates to a kind of central venous catheter.
Background technology
Central venous catheter is a kind of common medical apparatus and instruments, and it inserts the vein of patient by puncture technique, and such as subclavian vein, infuses to patient.At present, use central venous catheter clip sub-folder can be used to close connection tube after liquid input in case Hemostatic Oral Liquid outflow clinically, adopt low concentration heparin sodium tube sealing effectively to block by prevention center venous duct.It is cause the risk factor of connection tube front end breakage (clinical existing analogue occurs) that prolonged and repeated use clip sub-folder closes connection tube, if there is analogue, again inserts after renewing pipe after central venous catheter need being extracted again.Carry out the difficulty of anthropic factor not only to clinical medical and nursing work strip, also may bring serious misery to patient.
Utility model content
In view of the above problems, this utility model is intended to propose a kind of two-part central vein catheter.
The utility model proposes a kind of central venous catheter, it comprises: built-in pipe, holder, connecting hose, clamp, union joint; Built-in pipe, holder, connecting hose, union joint connect in turn, and clamp is arranged in connecting hose, by the slit optionally tube sealing that clamp is offered; Described connecting hose is formed as two sections, and the first end of first paragraph is connected with holder, and the second end of first paragraph forms connecting device; The first end of second segment forms connecting device, and the second end of second segment is connected with union joint, and clamp is arranged on second segment; The connecting device of first paragraph and the connecting device of second segment are removably fixed together.
Preferably, the connecting device of described first paragraph and the connecting device of second segment are together by a threaded connection.
Preferably, the connecting device of described first paragraph and the connecting device of second segment are linked together by buckle.
Preferably, the connecting device of described first paragraph and the connecting device outside of second segment are provided with containment vessel further; The connecting device of described containment vessel around described first paragraph and the connecting device of second segment.
Preferably, described containment vessel comprises the circuit be made up of ultraviolet LED, battery, switch further, and wherein ultraviolet LED is arranged in containment vessel.
Because central venous catheter of the present utility model adopts the form of two sections, easily damaged second segment is replaced in time when there is damage, re-start without the need to extracting whole central venous catheter and put pipe operation, greatly reduce the misery of patient, also save equipment, reduce the medical treatment cost of patient.

Detailed description of the invention
Below, by reference to the accompanying drawings central venous catheter of the present utility model is described in detail.
Central venous catheter of the present utility model, it comprises: built-in pipe 10, holder 20, connecting hose 30, clamp 35, union joint 40.Built-in pipe 10, holder 20, connecting hose 30, union joint 40 connect in turn, and clamp 35 is arranged in connecting hose 30, by the slit optionally tube sealing that clamp 35 is offered.
Connecting hose 30 is formed as two sections, and the first end of first paragraph 31 is connected with holder 20, and the second end of first paragraph 31 forms connecting device 32; The first end of second segment 34 forms connecting device 33, and the second end of second segment 34 is connected with union joint 40, and clamp 35 is arranged on second segment 34.The connecting device 32 of first paragraph 31 is removably fixed together with the connecting device 33 of second segment 34.Although not shown, connection here can be threaded or buckle connection, also can be that plug-in type connects.
As shown in Figure 4, in order to prevent, the connecting device 32 of first paragraph 31 and second segment 34 are unexpected to depart from, and the connecting device 32 of first paragraph 31 is provided with containment vessel 36 further with connecting device 31 outside of second segment 34.The connecting device 32 of containment vessel 36 around first paragraph 31 and the connecting device 33 of second segment 34.As shown in Figure 5,6, containment vessel 36 can be formed as column, and be divided into two parts semi-cylindrical 36a, 36b, semi-cylindrical 36a, 36b are rotatably connected to together by pivot 36c.
Owing to have employed two-part structure; there is the connector between the connecting device 32 of the first paragraph 31 that easily contaminated or pathogenic bacteria invades and the connecting device 33 of second segment 34 in connection tube 30; in order to eliminate this defect; containment vessel 36 comprises the luminescence-utraviolet circuit be made up of ultraviolet LED, battery, switch further; wherein ultraviolet LED is arranged in containment vessel 36; utilize ultraviolet often to sterilize to connector, effectively avoid the intrusion of antibacterial or pathogenic bacteria.
Central venous catheter of the present utility model, by connection tube is designed to two sections, when the second end occurs strain or be damaged, only needs to replace second segment easily, makes patient avoid again carrying out putting pipe operation, has saved medical treatment cost simultaneously.
