Abstract
The utility model discloses a left atrium and right atrium combined pressure measuring catheter. The left atrium and right atrium combined pressure measuring catheter comprises a three-cavity catheter and a micro-catheter. The three-cavity catheter comprises a center catheter and two side branch catheters. A Y-shaped connector is connected to the outer end of the center catheter and is provided with a straight opening and a side opening, and a certain angle is formed between the straight opening and the side opening. The micro-catheter is inserted into the center catheter through the straight opening. Compared with the prior art, because the Y-shaped connector is connected to the center catheter, an additional infusion channel can be formed through the Y-shaped connector when the pressure of the left atrium and the pressure of the right atrium are monitored during an operation, and heparin or other types of liquid medicine can be conveniently infused into the center catheter. The left atrium and right atrium combined pressure measuring catheter is simple in structure and easy and convenient to operate.
Description
Technical field
This utility model relates to medical apparatus and instruments, relates in particular to the left atrium associating pressure catheter that a kind of operation on heart is used.
Background technology
In Pediatric Cardiac Surgery, need to combine and carry out real-time central venous pressure monitoring, infusion medicinal liquid, blood specimen collection etc. left atrium, right atrium.The method of monitoring clinically left atrium pressure at present in operation on heart is to implant three cavities conduit pipe, in the central canal of three cavities conduit pipe, be inserted in again a microtubular simultaneously, wherein microtubular exposes three cavities conduit pipe front end 8cm left and right, makes microtubular through interatrial septum, put into left atrium monitoring left atrial pressure and transfusion.For preventing that the gap formation thrombosis between microtubular and central canal from causing microtubule can not pull out, need between microtubular and central canal, inject heparin, but the joint of current three cavities conduit pipe central canal only has an interface, while injecting heparin or other medicinal liquid, need to extract microtubular, operate extremely inconvenient.
Summary of the invention
In view of this, provide a kind of left atrium associating pressure catheter that can conveniently inject other medicinal liquid when monitoring atrial pressure.
A kind of left atrium associating pressure catheter, comprise three cavities conduit pipe and microtubular, described three cavities conduit pipe comprises that centre pipe and two sides prop up conduit, the outer end of described centre pipe is connected with breeches joint, described breeches joint be formed with straight mouthful and with straight mouth side mouth at an angle, described microtubular inserts in centre pipe via described straight mouthful.
Compared to prior art, this utility model left atrium associating pressure catheter arranges breeches joint on centre pipe, intra-operative is in monitoring left and right atrium pressure, by the extra infusion channel of the side interruption-forming of breeches joint, can in centre pipe, input heparin or other medicinal liquid easily, simple in structure, easy and simple to handle.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model left atrium associating pressure catheter.
The specific embodiment
Below with reference to the drawings and the specific embodiments, this utility model is elaborated.
As shown in Figure 1, this utility model left atrium associating pressure catheter comprises three cavities conduit pipe 10 and microtubular 30, and wherein, described microtubular 30 is inserted in described three cavities conduit pipe 10.
Three conduits that described three cavities conduit pipe 10 comprises catheter block 11, is connected in the body 13 of catheter block 11 inner sides and is connected in the outside of catheter block 11, centre pipe 15 and left and right two sides are propped up conduit 17.It is fixing by catheter block 11 that described centre pipe 15 and left and right side prop up conduit 17, and be connected with body 13.Wherein, the outer end that described left and right side props up conduit 17 is connected with respectively straight type joint 18, often on type joint 18, is formed with an interface always.The outer end of described centre pipe 15 is connected with breeches joint 16, described breeches joint 16 be formed with one straight mouthful 160 and with this straight mouthful 160 side mouth 162 at an angle, in the present embodiment, described straight mouthful 160 is standard 6% (Rule) tapering joint with side mouth 162, can other modular connection of fine cooperation use.
The inner of described microtubular 30 is inserted into the centre pipe 15 of described three cavities conduit pipe 10 and is entered body 13 final through described body 13 via described catheter block 11 by the straight mouth 160 of described breeches joint 16, the outer end of microtubular 30 is exposed to outside the straight mouth 160 of described Y type joint, and is connected with microtubular joint 32.
During use, a described left side, conduit 17 is propped up by the straight type joint 18 connecting on it in right side, described microtubular 30 is connected with monitoring equipment respectively by the microtubular joint 32 connecting on it, described microtubular 30 is together with three cavities conduit pipe 10 in implant into body, the inner of microtubular 30 is stayed and is implanted in left atrium, body 13 stays and is implanted in right atrium, so, the pressure of left atrium is reflected on the monitoring equipment being attached thereto by microtubular 30, the pressure of right atrium is by body 13, catheter block 11, left/right side is propped up conduit 17 and is reflected on corresponding monitoring equipment, realization is to a left side, the synchronous monitoring of the pressure of right atrium.
Because this utility model left atrium associating pressure catheter arranges breeches joint 16 on centre pipe 15, intra-operative is in monitoring left and right atrium pressure, the side mouth 162 that can pass through breeches joint 16 is to the interior input heparin of centre pipe 15, so the heparin of input is filled the gap between microtubular 30 and body 13, preventing from forming thrombosis causes microtubular 30 not extract, guarantee the safety of operation, described side mouth 162 is as extra infusion channel simultaneously, convenient other medicinal liquid of input, simple in structure, easy and simple to handle.
It should be noted that; this utility model is not limited to above-mentioned embodiment; according to creative spirit of the present utility model; those skilled in the art can also make other variations; the variation that these are done according to creative spirit of the present utility model, within all should being included in this utility model scope required for protection.
