Technical field
The utility model is related to a kind of urine guide frame more particularly to a kind of rotary catheter structures.
Background technology
The known catheter clinically used has been applied for many years, and catheter is mainly made of a longer pvc pipe,
Although the comparative maturity of such catheter application, still there are big inconveniences when application.It is firstly, since traditional
Catheter be all longer flexible rubber hose, by plastic packaging bag carry out pack, and so the space occupied it is larger, it is unfavorable
With the carrying and storage of people；However to tear packaging bag and be used, carried and stored, since catheter and air or hand connect
Germ contamination will likely be subject to by touching, and influence the safety and health of people.In addition pvc pipe is larger to urethral mucosa irritation, easily makes
Into the discomfort of patient.
Utility model content
The utility model provides a kind of to human body stimulation to solve above-mentioned defect in the prior art and deficiency
Property small, convenient storage, can directly take, when storage, occupies little space, and in terms of carrying, when use can directly carry out import operation,
Safety and sanitation, and the silica gel on head is small to human body irritation, can greatly improve the rotary catheter knot of patient comfort
Structure.
The technical solution of the utility model：A kind of rotary catheter structure including shell and sets leading inside the shell
Urinary catheter, the urethral catheterization bottom of the tube are connected by a screw thread rotation head with outer casing inner wall, and the outer casing bottom is equipped with a rotary joint,
The rotary joint is equipped with several guide rods, and the screw thread rotation head is connected by guide rod with rotary joint, the shell
Inner wall is equipped with internal thread, and the screw thread rotation head is equipped with the external screw thread of cooperation internal thread, and the cover top portion is equipped with cooperation
The capping of the silica gel head and cooperation silica gel head of catheter.
Inside the shell, convenient storage occupies little space, in terms of carrying for catheter storage in the utility model, during use
Capping back-out out of shell, which need to only be opened, can directly carry out import operation, can directly take, safety and sanitation, and the silica gel on head
It is small to human body irritation, patient comfort can be greatly improved.
Preferably, the quantity of the guide rod is two, and two guide rods are vertically arranged on rotary joint, the screw thread
The guide through hole of cooperation guide rod there are two being set on swivel head.
It is more steady reliable that this kind of structure ensures that screw thread rotation head rotates upper and lower displacement inside the shell, so as to drive catheter
It moves up and down inside the shell more steady reliable.
Preferably, two guide rods are symmetrically located at the both sides of catheter.
This kind of structure further improves the steady reliability that catheter moves up and down inside the shell.
Preferably, the arc concave shape being equipped on the inside of the silica gel head at the top of cooperation catheter, silica gel overhead are equipped with cooperation
The urethral catheterization through hole of catheter.
This kind of structure ensures to can be very good to move together with the cooperation of silica gel head when stretching out from shell at the top of catheter.
Preferably, the silica gel head bottom is equipped with buckle ring, and the baffle ring of cooperation buckle ring is equipped on the inside of the cover top portion.
This kind of structure ensures to can be very good to be mounted on cover top portion when silica gel head is not assembled with catheter, prevents it from coming off
(since silica gel head is soft connector, when catheter withstands its catheter can be followed to stretch out together).
Preferably, the shell upper is equipped with capping linkage section, and the capping linkage section is equipped with capping retainer ring.
This kind of structure ensures capping and the fastness of cage connection, ensures health during catheter storage.
Inside the shell, convenient storage occupies little space, in terms of carrying for catheter storage in the utility model, during use
Capping back-out out of shell, which need to only be opened, can directly carry out import operation, can directly take, safety and sanitation, and the silica gel on head
It is small to human body irritation, patient comfort can be greatly improved.
Description of the drawings
Fig. 1 is the schematic cross-sectional view of the utility model；
Fig. 2 is the exploded perspective view of the utility model；
