Description
Technical field
The utility model belongs to technical field of medical equipment, and in particular to multi-cavity catheter.
Background technique
Catheter is the tubular body for medical treatment, can be divided into external application and use two types in vivo.The former is for various
Gas, liquid conveying, such as stethoscope sebific duct, infusion sebific duct；The latter is generally called medical gum-elastic catheter, can be divided into single-chamber again by structure
Pipe and multi-lumen tube.
Only one inner cavity of single lumen catheter, multi-lumen tube are performed the operation for medical surgery, and there are two above inner cavity, (such as two-chamber stops blooding
Catheter, double air bags three cavities pipe etc.), multi-cavity catheter all has one or two tatex baloon, plays closing or contention effect.Rubber
Conduit system is inserted into the rubber tube of human body chamber and blood vessel, for injection of medicine or the internal liquid of extraction and the opening journey for determining lumen
Degree.
Currently, in order to mitigate the awake lower pain being intubated of patient's operation consent, usually first will in clinical use catheter
Patient anaesthetizes.In intubation, in order to avoid, to the frictionally damage of vascular wall, and going to select as far as possible when being inserted into blood vessel
The frictional force between conduit and vascular wall is reduced, though the protection to blood vessel can be reached in this way, after the arcotic of patient is out-of-date,
Usually due to turn over etc. movement and affect conduit slide in the blood vessels perhaps shake conduit will with vascular wall generate collide or
It falls off, this can allow patient to feel very painful or cause trouble to doctor, it is therefore desirable to which the multi-cavity medical treatment of the prior art is led
Pipe improves.
Utility model content
The purpose of this utility model is that solve the above-mentioned problems and provides multi-cavity catheter.
The utility model achieves the above object through the following technical schemes:
Multi-cavity catheter,
Including for carrying out main pipeline derived from drug conveying or urine；
Round table-like anti-dropout and drug structure for conveying including being internally provided with circular through hole, anti-dropout and drug conveying knot
Structure includes gas-filled cavity, pharmacological delivery lumen and connection cavity, gas-filled cavity, pharmacological delivery lumen and the equal fixing sleeve of connection cavity
On main pipeline, gas-filled cavity is positioned close at the insertion end of main pipeline, pharmacological delivery lumen setting in gas-filled cavity and
Between connection cavity；
Including inflator, the side of inflator is fixed on main pipeline, and the gas output end of inflator is connected with a gas
Pipe, tracheae are connected to after sequentially passing through connection cavity and pharmacological delivery lumen with gas-filled cavity；
Pharmacological delivery lumen is connected to connection cavity, is provided on the side wall of pharmacological delivery lumen multiple for drug exudation
Hole.
Specifically, the piston that can be extracted and fill in is provided on one end in connection cavity far from pharmacological delivery lumen.
Specifically, gas-filled cavity be in inflation expansion, without gas when shrink and be adjacent to the plastic chamber of main pipeline.
Further, the side wall of gas-filled cavity is provided with multiple protrusion air bags for preventing from skidding with flesh contact, more
A prominent air bag is connected to gas-filled cavity.
The utility model has the beneficial effects that:
The utility model multi-cavity catheter main pipeline and human body wound can be fixed by gas-filled cavity, and
It is not easily to fall off；It can be to conveying drug continual at wound, to prevent from infecting or stop blooding by pharmacological delivery lumen；And
The gas-filled cavity mounting structure and installation form of the utility model are more special, so that client reduces pain when being plugged in conduit
It is bitter.
Detailed description of the invention
Fig. 1 is the working state structure schematic diagram of the utility model；
Fig. 2 is the off working state structural schematic diagram of the utility model.
In figure: 1- main pipeline, 2- gas-filled cavity, 3- pharmacological delivery lumen, 4- connection cavity, 5- inflator, 6- piston.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
As shown in Figure 1 and Figure 2, multi-cavity catheter, including for carrying out main pipeline 1 derived from drug conveying or urine；
Round table-like anti-dropout and drug structure for conveying including being internally provided with circular through hole, anti-dropout and drug structure for conveying include filling
Air cavity 2, pharmacological delivery lumen 3 and connection cavity 4, the fixed suit of gas-filled cavity 2, pharmacological delivery lumen 3 and connection cavity 4
On main pipeline 1, gas-filled cavity 2 is positioned close at the insertion end of main pipeline 1, and pharmacological delivery lumen 3 is arranged in gas-filled cavity 2
Between connection cavity 4；Including inflator 5, the side of inflator 5 is fixed on main pipeline 1, the gas output end of inflator 5
It is connected with a tracheae, tracheae is connected to after sequentially passing through connection cavity 4 and pharmacological delivery lumen 3 with gas-filled cavity 2；Drug conveying
Cavity 3 is connected to connection cavity 4, and multiple holes for drug exudation are provided on the side wall of pharmacological delivery lumen 3.
The piston 6 that can be extracted and fill in is provided on one end in connection cavity 4 far from pharmacological delivery lumen 3.
Gas-filled cavity 2 be in inflation expansion, without gas when shrink and be adjacent to the plastic chamber of main pipeline 1.
The side wall of gas-filled cavity 2 is provided with multiple protrusion air bags for preventing from skidding with flesh contact, multiple prominent gas
