At present, most of the fixing methods of the drainage tube are suture fixing, and the specific method is as follows: after the drainage tube is arranged, a suture is sewed on the skin, and then the drainage tube is tied and fixed by the suture. However, sutures have the following disadvantages: 1. the traction of the suture line often causes pain and discomfort of patients and even abnormal pain, and patients who are provided with the drainage tube are feared mentally. 2. The drainage tube is easy to fall off when the patient is manually moved, turns over and lies up or down after operation. 3. Some drainage tubes need to be placed for a long time (such as drainage tubes for draining bile or gastrointestinal tracts and bladder fistulation tubes which can be placed for months, years or even lifetime), and after the drainage tubes are placed for a long time, the suture forms cutting on the skin, so the drainage tubes are easy to loosen and fall off; 4. gaps are often formed around the drainage tube, and gas or liquid easily overflows from the gaps to pollute the wound. The entry of gas from outside the body into the chest cavity can also be dangerous to the patient. 5. When the drainage tube is taken, the fixing thread needs to be cut off and drawn out from the tissue, the pain of the patient is not to say, and the cost is increased by using scissors.

Examples

Referring to fig. 1, the present embodiment provides a double-balloon drainage tube, which relates to the technical field of medical devices and comprises a main tube 1.

Referring to fig. 1, a flow guide channel 2, a first gas injection channel 11a and a second gas injection channel 11b are arranged in the main pipe 1; the front end of the first gas injection channel 11a is communicated with the spherical air bag 3 wrapped on the main pipe 1, and the tail end thereof is separated from the main pipe 1 and is communicated with the first gas injection valve 4; the front end of the second air injection channel 11b is communicated with the tubular air bag 5 wrapped on the main pipe 1, the tail end of the second air injection channel is separated from the main pipe 1 and is communicated with the second air injection valve 6, and after the tubular air bag 5 is inflated and expanded, the double-bag drainage tube is in a dumbbell shape.

Referring to fig. 3, the front end of the main pipe 1 is about 30-40 cm long, and a hole is formed at the trimming end 12. The spherical air bag 3 is about 2.0-3.0 cm long, the spherical air bag is spherical after being inflated, the diameter is about 2.0-3.0 cm, and the tubular air bag 5 is about 15-20 cm long, under the condition of no external force, the tubular air bag 5 is inflated on the surface of the main pipe 1 in a cylindrical shape after being inflated, so that the diameter of the original main pipe 1 can be increased by about 0.6-1.0 cm, namely the tubular air bag 5 is inflated outwards on the surface of the main pipe 1 by about 0.6-1.0 cm (0.3-0.5 cm on each side). The main tube 1 is about 100-140 cm long and 5-36 Fr thick (i.e. about 1.8-12 mm in diameter) to meet various clinical requirements.

Referring to fig. 2-8, when in use, the main tube 1 is firstly placed into a position needing drainage in a body cavity 7, the tail end is placed outside the body, the spherical air sac 3 is placed on the inner side 8 deep surface of the body wall of the body cavity 7 to be drained, the tubular air sac 5 penetrates through the body wall 9, the tubular air sac 5 is inflated and expanded to be cylindrical, certain pressure is generated on the surrounding body wall 9 tissue, and the front end of the tubular air sac 5 is tightly attached to the rear end of the spherical air sac 3.

Clinically, for the convenience of insertion and removal, the surface of the whole main tube 1 (including the spherical balloon and the tubular balloon) may be coated with a super-smooth coating.

Before placing, the trimming end 12 in front of the double-balloon drainage tube main tube 1 can be trimmed according to the required length, and if necessary, a plurality of side holes (the side holes are generally within 5cm at the front end) can be trimmed at the front end part after trimming. Then, the front part (including the spherical air sac) of the double-sac drainage tube main tube 1 is placed into a body cavity 7 to be drained through a placing method or an operation incision, a plurality of milliliters of air or physiological saline are injected through a first air injection valve 4 of the spherical air sac 3, the air or the physiological saline enters the spherical air sac 3 through a first air injection channel 11a to inflate and expand the spherical air sac 3, then the drainage main tube 1 is pulled outwards by slight force to ensure that the spherical air sac 3 is tightly attached to the inner side 8 of the body wall of the body cavity 7, then a plurality of milliliters of air or physiological saline is injected through a second air injection channel 11b through a second air injection valve 6 of the tubular air sac 5 to inflate and expand the tubular air sac 5, and when a patient feels slight distending pain or an operator feels large rebound force, the inflation and expansion are stopped, so that the inflated and expanded tubular air sac 5 generates certain pressure on the tissues of the. Due to the extrusion effect of the body wall 9, after the tubular air sac 5 is inflated and expanded, the air or physiological saline in the tubular air sac flows to the part outside the body which is not extruded to form an external expansion section 10, so that the expanded spherical air sac 3 and the external expansion section 10 of the tubular air sac 5 form a dumbbell-shaped structure with two large ends and a small middle part, and the drainage main pipe 1 is fixed on the body wall 9.

After drainage is finished, the double-sac drainage tube needs to be pulled out, air or normal saline in the tubular air sac 5 and the spherical air sac 3 is respectively pumped out, and then the main tube 1 is pulled out slightly.

Due to the functions of the spherical air bag 3 and the tubular air bag 5, the main drainage tube 1 does not need to be specially fixed in vitro, thereby relieving the pain of a patient.

The end opening of the main pipe 1 and the openings of the first air injection valve 4 and the second air injection valve 6 are all conical joints for medical instruments, and can be connected with medical instruments such as a drainage bag, a syringe, a pressure pump and the like.

In another embodiment, the outer surface of the main tube 1 is further provided with a scale 13 (not shown) for accurately measuring and monitoring the placement depth of the double-balloon drainage tube.

The double-balloon drainage tube disclosed by the embodiment is provided with the pruning end 12 capable of pruning, the front end of the main tube 1 of the double-balloon drainage tube can be properly pruned according to the actual condition of a patient, so that the double-balloon drainage tube can be accurately positioned at the drainage position, and is limited on the body wall 9 by the two air bags, the double-balloon drainage tube can be prevented from falling off, the skin of the patient is not required to be sewn and fixed, the pain of the patient is relieved, liquid leakage and air leakage can be prevented simultaneously, the safety of the patient is guaranteed, the life quality of the patient is improved, and the double-balloon drainage tube has the beneficial effects of being good in limit and sealing performance and conveniently realizing the drainage of the double-balloon drainage tube.
