When described utricule uses non-resilient shrinkable material, can need to produce the utricule of given shape according to operation, it is simple to obtain more suitably operation path.
Described utricule inwall can be provided with reinforcement.
Described utricule is one or more layers；When using multilamellar sacculus, if the explosion of innermost layer sacculus, redundancy protecting layer can be served as by outer layer.
Described union joint is by sacculus and conduit compact siro spinning technology.
Described conduit for flexible, in thread a pipe.
Described gas-liquid infusion assembly is three way type structure, the two of which through hole of described threeway respectively connects a check valve, and wherein, check valve one is connected with conduit, check valve two can connection traffic control member, another through hole of threeway can connect syringe, air bag or other gas injection liquid parts.When using the gas-liquid infusion assembly of three way type structure, syringe can extract and infusion gas-liquid in utricule continuously；Described check valve one is the one-way flow towards conduit, and check valve two is the one-way flow towards threeway.
Described flow control member includes Liquid extracting flexible pipe and the parts of stored liquid being connected with the flexible pipe other end；The described parts storing liquid can be water bag, water tumbler, water bottle etc..Preferably, the signable scale of member outer surface of liquid can be stored so that can accurately know the capacity injecting liquid according to scale, prevent from, because of the fluid injection excessive expanding blasting of too much sacculus, histoorgan in the patient being caused damage during sacculus fluid injection expanse.
Operation principle:
During operation, extrude sacculus, discharge the gas in sacculus.Being placed in by sacculus in operation gap, gas or liquid continuous print can be injected in sacculus by the device such as syringe of suction gas-liquid by gas-liquid infusion assembly.
This device hinge structure its provide the benefit that: the sacculus process that industrialization manufactures, it is not easy to burst, sacculus and conduit compact siro spinning technology, will not deviate from because of the reason of pressure in inflated or water filling process；Device after oxirane or irradiation sterilization can guarantee that aseptic, reduces the probability that operation occurs to infect；The existence of gas-liquid infusion assembly makes to become simple to the process of inflated or water-filling, once rush note to complete to need not folder and close conduit, again bleeding and extract from conduit also without by the device such as syringe of suction gas-liquid, continuous punching note makes process smooth, saves operating time.
