Description
Technical Field
The utility model relates to a medical instrument field, concretely relates to device convenient to link up, stay appearance and prevention jam.
Background
Biliary tract drainage tubes are often used for bile drainage in liver surgery and biliary tract minimally invasive surgery to relieve the illness state of a patient, and generally, one end of the biliary tract drainage tube, which is positioned outside the body, is provided with a threaded interface so as to be conveniently connected with other medical supplies. In clinic, a disposable drainage bag is generally required to be externally connected after the catheter is placed, so that the condition of bleeding, infection and the like after the operation can be conveniently observed.
However, the liquid inlet pipe interface of the drainage bag is generally a conical joint, which is not matched with the threaded interface of the biliary tract drainage pipe. The current connection operation of the drainage bag and the biliary tract drainage tube is as follows: firstly, medical personnel need to use local materials, a screw port at the front end of the transfusion catheter is disassembled to serve as a connecting component, one end of the screw port is connected with a connector of the drainage bag in an inserting mode through a section of rubber tube (or latex tube), and the other end of the screw port is provided with threads and is in threaded connection with an external connector of the biliary tract drainage tube. In the operation, at least one infusion catheter needs to be wasted, in addition, the infusion catheter is provided with a filter screen in a threaded hole, and a needle needs to be used for puncturing before use, so the operation not only causes material waste, but also causes low working efficiency.
Clinically, still need leave the sample according to the state of an illness and carry out the inspection examination, but the biliary tract drainage tube sample that is located the external at present is very inconvenient, and this is because this pipe material is harder, and inconvenient adoption clinical pjncture needle disinfection is left and is got, can prick the pipe and omit drainage liquid, increases patient's expense burden simultaneously. The traditional operation mode is usually that a sample is directly reserved from an outer end interface of the biliary tract drainage tube, and the drainage bag is replaced again, but the sample reserving operation can cause pollution, and the infection probability is increased.
In addition, the biliary tract anatomical system is more complicated, the patient's state of an illness is different, place the biliary tract drainage tube through the percutaneous liver puncture biliary tract drainage technique, the nature, the colour, the volume of bile and the secretion of drainage are different, can arouse the stifled pipe phenomenon along with the development of the state of an illness, it often needs to guide patient and family members to turn over external drainage bag pipe part to push to prevent to block up the pipe phenomenon to often to prevent to take place to push in the ward visit period to prevent to block up the pipe phenomenon clinically, though this easy operation, it can influence the unobstructed degree of pipe to turn over an extrusion pipe, also can be interrupted the clamp catheter (if twine with the rubber band or with the pipe fifty percent discount) according to the needs of the state of an illness development sometimes clinically, but when opening the catheter once more, the distortion has usually appeared in the pipe and has.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-4, the device for facilitating connection, sample retention and blockage prevention comprises a drainage tube blockage prevention sample retention device, which comprises an upper hose 1, a valve part 2 and a lower hose 3. Is used in combination with biliary tract drainage tube and drainage bag.
The upper hose is composed of a biliary tract end connector 11, a sacculus 13, a sampling port 14 and a valve upper connector 15, the biliary tract end connector 11 is internally of a spiral structure, and is convenient to be connected with a biliary tract drainage tube connector and has a good sealing effect. Wherein, an extension tube 12 is arranged between the biliary tract end joint 11 and the sacculus 13, which is convenient for strengthening the negative pressure effect when the sacculus 13 is extruded.
The valve part 2 is made of hard material such as ABS, the upper joint 21 and the lower joint 24 are both in a step-shaped or pagoda-shaped structure, so that the upper hose 1 and the lower hose 3 are tightly connected to prevent liquid from seeping out. Between the valve 23 and the sampling port 14 is a sample retaining part 22, which functions to retain the sample when the valve 23 is closed.
The sampling port 14 is made of soft sealing materials such as silica gel and the like, such as silica gel, latex and the like, when sampling, a needle is used for puncturing the sampling port 14 and extracting a sample at a sample retaining position 22, and when the needle is pulled out, the sampling port 14 is automatically closed and sealed, so that liquid seepage cannot be caused.
The lower hose 3 consists of a lower valve connector 31 and a drainage bag connector 32, the head of the drainage bag connector 32 is slightly thickened, so that a port of a drainage belt can be conveniently inserted, and the hose is made of elastic materials and has a good sealing effect.
