[0026] Embodiment 1

[0027] Referring to Figures 1 to 4 , this is the first embodiment of the present utility model. This embodiment provides an indwelling double-lumen catheter for facilitating nursing. The indwelling double-lumen catheter for facilitating nursing includes a valve assembly 200, a connection assembly 300, and a diversion assembly 100. The three cooperate to perform bladder perfusion and collect midstream urine culture from one side of the catheter.

[0028] The valve assembly 200 includes a three-way pipe 201a, a rotary valve 201b, and a rotating shaft 201c. The rotary valve 201b is disposed inside the three-way pipe 201a. The rotating shaft 201c is fixed to the top of the rotary valve 201b. The rotating shaft 201c is inserted into the top of the three-way pipe 201a, and the rotating shaft 201c is movably connected to the three-way pipe 201a.

[0029] The rotary valve 201b is provided with three flow ports. The initial position of the rotary valve 201b is to connect the catheter body 101 with the urine bag 103. When injecting from the connection port on one side of the tee 201a, by rotating the rotary valve 201b, the rotary valve 201b is rotated to connect the catheter body 101 with the connection port on one side of the tee 201a. At this time, the catheter body 101 will be sealed with the urine bag 103, so that injection can be carried out into the patient's body. By rotating the rotating shaft 201c, the rotary valve 201b can be driven to rotate.

[0030] The connection assembly 300 is arranged on the tee 201a and includes a first clamping block 301a, a first guiding strip 301b, a connecting pipe 301c, a second clamping block 301d and a second guiding strip 301e. The first clamping block 301a is fixed on one side of the tee 201a, the first guiding strip 301b is fixed to one side of the first clamping block 301a, the connecting pipe 301c is located on one side of the tee 201a, the second clamping block 301d is fixed to one side of the connecting pipe 301c, and the second guiding strip 301e is fixed to one side of the second clamping block 301d.

[0031] By connecting the connecting pipe 301c to one side of the connection port on one side of the tee 201a, injection can be carried out into the patient's body. When connecting the connecting pipe 301c to one side of the tee 201a, in order to prevent the connecting pipe 301c from falling off from the tee 201a, by rotating the connecting pipe 301c, the rotation of the connecting pipe 301c can drive the second clamping block 301d to rotate, so that the second clamping block 301d contacts the first guiding strip 301b. At this time, the second guiding strip 301e will contact the first clamping block 301a. Through the guiding of the inclined guiding strip, the first clamping block 301a and the second clamping block 301d are clamped more tightly, preventing the connecting pipe 301c from separating from the tee 201a. When it is necessary to separate the connecting pipe 301c from the tee 201a, the two can be separated by reversing the connecting pipe 301c.

[0032] Embodiment 2

[0033] Refer to Figures 1 to 4 , which is the second embodiment of the present utility model. This embodiment is based on the previous embodiment.

[0034] Specifically, a rotating disc 202a is sleeved outside the rotating shaft 201c, and a rotating plate 202b is fixed on the top of the rotating shaft 201c.

[0035] The rotation of the rotating disc 202a can drive the rotation of the rotating shaft 201c, and the rotation of the rotating shaft 201c can drive the rotation of the rotary valve 201b. The rotating plate 202b is used to support the rotating shaft 201c to prevent the rotating shaft 201c from shifting.

[0036] Specifically, a torsion spring 202c is fixed to the top of the rotating disk 202a, and the torsion spring 202c is fixed to the bottom of the rotating plate 202b.

[0037] When the rotating disk 202a rotates, it can drive the rotating plate 202b to rotate. The rotation of the rotating plate 202b can apply a torsional force to the torsion spring 202c. The rotation of the rotating disk 202a drives the rotating valve 201b to rotate to connect with the connection port on one side of the three-way pipe 201a and the catheter body 101, so as to inject into the patient's body. When the injection is completed, the connecting pipe 301c is separated from the three-way pipe 201a, and the rotating disk 202a can be driven to rotate back to its original position by the returning force of the torsion spring 202c.

[0038] Specifically, a driving strip 302a is fixed to the top of the rotating disk 202a, and a driving rod 302b is sleeved outside the driving strip 302a. The driving rod 302b is hinged to the driving strip 302a.

[0039] The movement of the driving strip 302a can cause the rotating disk 202a to rotate. The orientation of the driving rod 302b is inclined. When the driving rod 302b is squeezed, it can drive the driving strip 302a to move. At this time, the movement of the driving strip 302a can drive the rotating disk 202a to rotate. A stop block is arranged on one side of the rotating disk 202a, and the stop block is fixed to the top of the three-way pipe 201a. The arrangement of the stop block can prevent the driving strip 302a from moving in the reverse direction when being squeezed, resulting in the reverse rotation of the rotating disk 202a.

[0040] Specifically, a driving block 302c is fixed to one end of the driving rod 302b.

[0041] Squeezing the driving block 302c can drive the driving rod 302b to move.

[0042] Specifically, a slider 302e is fixed to the bottom of the driving block 302c, and a sliding groove 201a-1 is formed at the top of the three-way pipe 201a. The slider 302e slides in the sliding groove 201a-1.

[0043] When the driving block 302c moves, it can drive the slider 302e to move. The slider 302e moving in the sliding groove 201a-1 can support the driving block 302c to prevent the driving block 302c from shifting when moving.

[0044] Embodiment 3

[0045] Refer to Figure 2 and Figure 3 , which is the third embodiment of the present invention, and this embodiment is based on the first two embodiments.

[0046] Specifically, a push rod 302f is arranged on one side of the driving block 302c, and a push block 302g is fixed to one end of the push rod 302f.

[0047] When the side of the driving block 302c is set to be concave and the connecting pipe 301c is connected to one side of the tee pipe 201a, the push rod 302f will engage with the driving block 302c. At this time, the push rod 302f will squeeze the driving block 302c to make it move, and the movement of the push block 302g will drive the movement of the push rod 302f.

[0048] Specifically, a movable sleeve 302h is fixed to the bottom of the push block 302g. The movable sleeve 302h is sleeved outside the connecting pipe 301c, and the movable sleeve 302h is movably connected to the connecting pipe 301c.

[0049] When the connecting pipe 301c is connected to one side of the tee pipe 201a, it will drive the movement of the movable sleeve 302h. The movement of the movable sleeve 302h drives the movement of the push block 302g, and the movement of the push block 302g will drive the movement of the push rod 302f.

[0050] Specifically, it further includes a diversion assembly 100, which is arranged on the tee pipe 201a and includes a urinary catheter body 101 and an inflation tube 102. The urinary catheter body 101 is sleeved outside the tee pipe 201a, and the inflation tube 102 is fixed to one side of the urinary catheter body 101.

[0051] The urinary catheter body 101 is mainly used to drain urine from the bladder. It is usually made of a soft material so that it can be smoothly inserted into the urethra and reduce the irritation and damage to the urethral tissue. By inflating the inflation tube 102, the airbag at the front end of the urinary catheter body 101 expands, thereby fixing the urinary catheter body 101 in the bladder to prevent the urinary catheter from accidentally slipping out.

[0052] Specifically, a urine bag 103 is connected to one side of the tee pipe 201a.

[0053] The urine bag 103 is used to provide sufficient capacity to hold the urine discharged by the patient and avoid urine overflow causing pollution and inconvenience.

[0054] During use, when it is necessary to inject into a patient's body, first connect the connecting tube 301c to one side of the three-way tube 201a. When connecting the connecting tube 301c to one side of the three-way tube 201a, the push rod 302f will engage with the driving block 302c. The movement of the push block 302g will drive the movement of the push rod 302f. The movement of the push rod 302f drives the movement of the driving block 302c. By squeezing the driving block 302c, the driving rod 302b can be driven to move. When the driving rod 302b is squeezed, the driving strip 302a can be driven to move. At this time, the rotation of the driving strip 302a can drive the rotation of the rotating disk 202a. When the rotating disk 202a rotates, the rotating plate 202b can be driven to rotate. The rotation of the rotating plate 202b can apply a torsional force to the torsion spring 202c. The rotation of the rotating disk 202a drives the rotation of the rotary valve 201b to connect the catheter body 101 to the connection port on one side of the three-way tube 201a. When connecting the connecting tube 301c to one side of the three-way tube 201a, to prevent the connecting tube 301c from detaching from the three-way tube 201a, by rotating the connecting tube 301c, the rotation of the connecting tube 301c can drive the rotation of the second latch 301d, so that the second latch 301d contacts the first guiding strip 301b. At this time, the second guiding strip 301e will contact the first latch 301a. Through the guiding of the inclined guiding strip, the first latch 301a and the second latch 301d are more tightly engaged, preventing the connecting tube 301c from separating from the three-way tube 201a, so that injection into the patient's body can be carried out. When the injection is completed, reverse the connecting tube 301c to separate the connecting tube 301c from the three-way tube 201a, and then the force of the torsion spring 202c returning can drive the rotating disk 202a to return to its original position.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
