Specific embodiment
Below and specific embodiment the utility model is described in further detail.
A kind of natural cavity protection sleeve pipe 10, as shown in figs. 1 to 6, including flexible pipe 12, internal ecto-entad are successively set
It is equipped with the inflow pipe 28 and body fluid discharge pipe 26 of heating or frozen liquid, is distally gone out wherein the inflow pipe 28 is equipped at least one
Mouth 20, which is provided with expandable bags 36, and (expandable bags formation one can be stored to be exported by inflow pipe
Place outflow heating or frozen liquid variable wall 38) expandable bags 36 proximally by local interface 32 and the flexible pipe 12
Distal end connects, and the distal end of expandable bags 36 passes through distal end sealing 34 and is tightly connected with 26 outer wall of body fluid discharge pipe, inflow pipe,
Expandable bags and flexible pipe form the circuit for heating or frozen liquid recycles.12 distal end of flexible pipe connects by second
First 30 are connected to the effuser 40 of heating or frozen liquid, and the proximal end of effuser 40 is connected to exhaust chamber 42.
Preferably, each remote outlet 20, which is designed to have, can make heating or frozen liquid centrifugation and inclination outflow
Shape.
Wherein, it is described flow into pipe 28 inner surface be equipped with spiral baffle, the spiral baffle have with it is described heating or it is cold
Freeze fluid towards each remote outlet 20 flow direction it is consistent spiral-shaped, so as to heat or frozen liquid itself row at spiral shell
Shape vortex is revolved, helps equably to extend the surface for flowing into pipe, while ensuring to flow into and manage in the contact surface with cavity wall
Flow is bigger, increases heat conduction efficiency.
Preferably, the proximal end of the inflow pipe 28 of the heating or frozen liquid is connected to the heating via the first connector 24
Or the admission chamber 22 of frozen liquid.
Preferably, the body fluid discharge pipe distal end stretches out the inflow pipe 28 of heating or frozen liquid and is stretching out the inflow
The part pipeline of pipe 28 is equipped at least one body fluid flow inbound port 16；Proximal end is stretched out first connector 24 and is drained with body fluid
Inner cavity 18 connects.
In order to which the proper temperature in cavity can be kept, prevent cavity organization from damaging and perforating.The heating or freezing stream
The aqueous solution of water or other temperature compatible with protection sleeve pipe and heating or freezing tissue that body is 37 DEG C, the heating or freezing
The temperature of fluid is realized by Heat preservation or refrigerating plant.
The natural cavity in the utility model can be human airway, alimentary canal, urethra, genital tract or nasal cavity: with
For urethra, when needing to carry out urethra heat preservation, as shown in fig. 7, the natural cavity protection sleeve pipe 10 of the utility model is inserted into
To the bladder 60 of patient, in use, in conjunction with 1~6 structure chart it can be concluded that, Urine in Patients pass through body fluid flow inbound port
16 enter the apocenosis passage 14 in body fluid discharge pipe 26, flow into body fluid drainage inner cavity 18 and excrete.In the same of urine drainage
Shi Kaiqi heating or frozen liquid channel, heating or frozen liquid are entered by admission chamber 22 and the first connector 24 to be flowed into pipe 28
Feed pathway 19 and via the remote outlet of flow ipe 20 flow into expandable bags 36 in variable cavity 38 in, using soft
Property pipe 12 in liquid outlet channel 37 be expelled to effuser 40, and then be discharged by exhaust chamber 42.After cryosurgery operates, this
The protection sleeve pipe 10 of utility model can drain protection sleeve pipe by normal urine and replace.
There is expandable bags 36 in the utility model variable cavity can change with the path of heating or frozen liquid, tool
There is the advantages of can preferably adhering to cavity inner wall.Material for expandable bags 36 needs to meet nontoxic and has high-elastic
Property, as expanded the shape for being readily able to accurately adapt to patient itself cavity inner cavity.
It is emphasized that high flow capacity and low pressure dynamic balance are the design cores of the utility model structure, because are as follows: this is practical
For novel protection sleeve pipe the result is that using in body cavities, the high flow capacity that high pressure maintains may have certain damage to cavity wall
Wound, and high pressure can exceed that the elastic range of flexible pipe or expandable bags, cause its can not in controlled range intramedullary expansion,
Then it explodes, brings damage to tissue.
The design of the protection sleeve pipe must assure that a high input flow rate and relatively high inlet pressure thus, and right
That answers is arranged low or negative pressure in exit, for example, the high efficiency flow in order to guarantee heating or frozen liquid, heating or freezing stream
The heating of body flowed into pipe 28 or frozen liquid are supplied by the first peristaltic pump, the corresponding flexible pipe 12 and may expand
Heating or frozen liquid in bag 36 controls the first peristaltic pump and the using control system by the suction discharge of the second peristaltic pump
The power of two peristaltic pumps, allow the barometric gradient formed between two pump housings maintain to have in protection sleeve pipe suitable volumes plus
Heat or frozen liquid pass through.
The utility model is described in detail in above embodiments, but the content is only the preferable reality of the utility model
Example is applied, should not be considered as limiting the scope of the present invention.Equalization made according to the scope of application of this utility model
Variation and improvement etc., should still belong within the patent covering scope of the utility model.
