Specific embodiment

It is described in more detail below in conjunction with T-type peritoneal cavity drainage tube external member of the schematic diagram to the utility model, wherein Illustrate the preferred embodiment of the utility model, it should be appreciated that those skilled in the art can modify described herein it is practical new Type, and still realize the advantageous effects of the utility model.Therefore, following description should be understood as those skilled in the art It is widely known, and be not intended as limitations of the present invention.

It as shown in figs. 1-7, is disposable T-type peritoneal cavity drainage tube.As depicted in figs. 1 and 2, the peritoneal cavity drainage tube is by wearing Bayonet head 1, drainage tube adapter 2, T-type drainage tube 3 and air bag 4 form.

The puncture cutter head 1 is taper cutter head 11 (as shown in Figure 3), and maximum gauge is slightly larger than the outer diameter of adapter 2, taper Cutter head 11 contains internal screw thread 12, and away from the side at T-type end, equipped with external screw thread, (such as Fig. 6, i.e. T-type draw 3 main part of T-type drainage tube The proximal end of flow tube 3), consequently facilitating puncturing 1 installation and removal of cutter head.Taper cutter head 11 can reduce the wound to skin.

Refer to Fig. 4 and Fig. 5, the drainage tube adapter 2 include in lead to the first drainage channel 21, the first gas injection end 22, the second gas injection end 24, the first water injection end 23 and the second water injection end 25.First drainage channel 21 runs through adapter 2, in drainage bag Insertion end 211 is stepped and has constant slope, is inserted into convenient for drainage bag, and built-in sealing ring 26 prevents liquid leakage.First The side of adapter 2 is arranged in gas injection end 22 and the first water injection end 23, and opening direction and the first drainage channel 21 are in obtuse angle, The connection such as more convenient and external equipment such as syringe, inflator pump.First gas injection end 22 and the first water injection end 23 are respectively with second Gas injection end 24,25 connection of the second water injection end.

First drainage channel 21 is protruding with drainage tube connecting pin 2 12 in 211 opposite side of drainage bag insertion end, the Two gas injection ends 24 and the second water injection end 25 protrude from one end that adapter 2 deviates from drainage bag insertion end 211, when adapter 2 and T-type When proximal end (side for deviating from T-type end) socket of drainage tube 3, drainage tube connecting pin 212, the second gas injection end 24 and second is filled the water 25 interference are held to be plugged in the second drainage channel 31 of T-type drainage tube main part, air vent channel 32 and waterflood path 33.Drawing Flow tube connecting pin 212, the second gas injection end 24 and 25 periphery of the second water injection end are provided with gasket seal 27, so that adapter 2 and T-type When drainage tube 3 is socketed, whole airtightness can be increased.

Fig. 6 and Fig. 7 are referred to, there are three channel, the respectively second drainages for its main part of T-type drainage tube 3 tool Channel 31, air vent channel 32 and waterflood path 33, above-mentioned one end of the channel (side docked with adapter 2) opening can divide Not with the drainage tube connecting pin 212 of drainage tube adapter 2, the second gas injection end 24,25 connection of the second water injection end, wherein stomata is logical 32 other end of road extends to inside air bag 4, the second drainage channel 31 and 33 other end of waterflood path respectively with third drainage channel 34 connection.

3 head end of T-type drainage tube is T-type structure, and the T-type end is placed in inside bile duct after operation, vertical with main part Section is hollow third drainage channel 34, and the waterflood path 33 punishes fork (being divided into two) in nearly third drainage channel 34, Oblique cutting enters 34 two sides of third drainage channel (as shown in Figure 7), and the blocking of third drainage channel 34 can be effectively prevented in above-mentioned design.

The T-type drainage tube 3 is provided with external screw thread 35 with 34 opposite side outer wall of third drainage channel, can be with stab knife First 1 is attached.

Scale 36 is indicated in 3 main part of T-type drainage tube, the position whether tube body has relative body can be observed in vitro It moves, convenient for scenting a hidden danger in time, reduces damage.At the nearly air bag 4 in 36 position of scale, when use, is exposed to outside skin.

Air bag 4 is in the deflated condition flat annulus shape, can preferably play fixed function, prevent third drainage channel 34 It slips, and can damage of the maximum mitigation to body.

T-type end is placed in bile duct after operation, drainage tube 3 is pierced into out skin of abdomen (such as Fig. 1 institute using cutter head 1 is punctured Show), it removes puncture cutter head 1 at this time, drainage tube adapter shown in Fig. 42 is mounted on T-type drainage tube 3 (as shown in Figure 2), then Drainage bag is accessed into drainage bag insertion end 211, built-in sealing ring 26 injects air from the first gas injection end 22 at the same time, makes Air bag 4 is heaved, and plays fixed function, third drainage channel 34 is effectively prevent to slip out of bile duct.It, can be under normal drainage state First water injection end, 22 injection of medicine etc., drug etc. can pour third drainage channel 34 by double waterflood paths 33 from Fig. 5, prevent third Blocking can not normal drainage in drainage channel 34.Whether there is the position that Relative Skin occurs by 36 observable tube body of scale in Fig. 5 It moves, in order to avoid cause to damage.

The preferred embodiment that above are only the utility model, does not play the role of any restrictions to the utility model. Any person of ordinary skill in the field, in the range of not departing from the technical solution of the utility model, to the utility model The technical solution and technology contents of exposure make the variation such as any type of equivalent replacement or modification, belong to without departing from the utility model Technical solution content, still fall within the protection scope of the utility model.
