Specific embodiment

According to the present invention will be described in detail below with reference to the accompanying drawings.

The self-service Colon and rectum narrow treatment device of double sacculus as shown in Figure 1 specifically includes that inner tube 1, outer tube 2, fixes Sacculus 3 and dilating sacculus 4.

The installation nested with outer tube 2 of inner tube 1, the both ends of inner tube 1 stretch out in outer tube 2, and inner tube 1 uses the rubber of long 30cm Pipe, outer tube 2 use the silicone tube of long 20cm, during insertion, since the supportive of inner tube 1 is better than outer tube 2, Neng Gouqi To the effect of guidance, outer tube 2 is driven accurately to arrive at affected part.The lateral wall of outer tube 2 is additionally provided with scale marker along its length 12, it can intuitively show the depth of insertion.

Fixed sacculus 3 is mounted on the distal end of inner tube 1, and the distal portions that inner tube 1 stretches out in outer tube 2 protrude into fixed sacculus 3 In, the proximal end of inner tube 1 is equipped with air valve 1, and proximal end can be connected to the inflatable structures such as air bag, by conveying to the proximal end of inner tube 1 Gas is to be inflated fixed sacculus 3, and air valve 1 is for controlling air-flow size.It follows that inner tube 1 not only acts as and draws The effect led, or the inflatable and deflatable pipeline of fixed sacculus 3.

Dilating sacculus 4 is arranged around the middle part of outer tube 2, and the gas injection into dilating sacculus 4 can play the work of differentially expanding With can be used for local Pressur hemostatic.The lateral wall of outer tube 2 is attached with snorkel 6 along its length, snorkel 6 Distal end is connected with dilating sacculus 4, and for being inflated to dilating sacculus 4, the proximal end of snorkel 6 is equipped with air valve 27, is used for Air-flow is controlled, proximal end can be connected to the inflatable structures such as air bag.

It is equipped with a ring shape liquid storage chamber 8 along tube wall inside outer tube 2, offers multiple side openings on the lateral wall of liquid storage chamber 8 9, side opening 9 is distributed between fixed sacculus 3 and dilating sacculus 4, and drug can be sprayed into enteric cavity by side opening 9.Outer tube 2 Inner sidewall is attached with perfusion tube 10 along its length, and perfusion tube 10 is fitted closely with 2 inner sidewall of outer tube, can minimize institute It takes up space, reduces the influence to 1 activity space of inner tube.The distal end of perfusion tube 10 is connected with liquid storage chamber 8, for liquid storage chamber 8 It is infused, the proximal end of perfusion tube 10 stretches out in outer tube 2 and is equipped with liquid feed valve 11, and proximal end can be connected to liquid pump, syringe Etc. infusion equipments, drug is delivered to liquid storage chamber 8, liquid feed valve 11 is for controlling flow rate of liquid.

Fig. 2 illustrates outer tube 2, inner tube 1, the positional relationship between liquid storage chamber 8, from cross-sectional view as can be seen that outer tube 2 The liquid storage chamber 8 of a ring shape is equipped with along inner tubal wall, the lateral wall (i.e. the tube wall of outer tube 2) of liquid storage chamber 8 is equipped with side opening 9, and interior Pipe 1 is located in the space that annular liquid storage chamber 8 is irised out.

It should be noted that the use of such as "upper", "lower", "left", "right", "front", "rear" cited in utility model Language is merely convenient to being illustrated for narration, rather than to limit the enforceable range of the utility model, the change of relativeness or Adjustment, under the content of no substantial changes in technology, when being also considered as the enforceable scope of the utility model.
