DETAILED DESCRIPTION

The following will be combined with the drawings in the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the utility model.

The present invention is described in detail below in conjunction with Figures 1 to 3 and specific embodiments:

As shown in Figures 1 to 3, the utility model provides a tube sealing device with its own tube sealing liquid, which includes a cavity 1, one end of the cavity 1 is formed with a cavity head 2, and the other end is formed with a liquid storage tank 5; a threaded cover 3, the threaded cover 3 is installed at the cavity head 2 of the cavity 1; a piston body 6, the piston body 6 is provided with a diaphragm 7 at one end close to the cavity head 2, and the piston body 6 is installed in the liquid storage tank 5 of the cavity 1; a push rod 11, the push rod 11 is provided with a piercing member 8 at one end close to the cavity head 2, one end of the push rod 11 extends into the piston body 6, is rotatably connected to the piston body 6, and a piston cavity 9 is formed between the push rod 11 and the diaphragm 7.

The cavity 1 and the cavity head 2 are an integrated structure, the liquid storage tank 5 is arranged inside the cavity 1, and the threaded cover 3 is installed at the cavity head 2. When the present sealing device is not in use, the threaded cover 3 and the cavity head 2 are in a sealed state. When the present capping device is in use, the threaded cover 3 is unscrewed to expose the cavity head 2 for use. The piston body 6 is provided with a diaphragm 7 at one end close to the cavity head 2, and the push rod 11 is provided with a piercing member 8 at one end close to the cavity head 2. One end of the push rod 11 extends into the piston body 6, so the piston body 6, the diaphragm 7 and one end of the push rod 11 form a piston cavity 9. Since the threaded cover 3 and the cavity head 2 are in a sealed state when the utility model is not in use, the liquid in the liquid storage tank in the cavity 1 will not flow out in the direction of the threaded sealing tube, and the piston cavity 9 formed by one end of the push rod 11 and the piston body 6 and the diaphragm 7 is equivalent to a second liquid storage tank, so the utility model can load two different solutions.

Furthermore, an external thread is formed at one end of the push rod 11 connected to the piston body 6, and correspondingly, an internal thread is formed in the piston body 6 to realize the rotational connection between the push rod 11 and the piston body 6. The piston body 6 is concave in design, and the push rod 11 is connected to the middle concave part, and one end of the push rod 11 extends into the interior of the piston body 6 and is tightly attached to the inner wall of the piston body 6, so that the piston cavity 9 becomes a sealed space. When the tube sealing device is used, a physiological saline solution with a single-portion ratio is pre-fabricated in the liquid storage tank 5, and a sodium heparin solution with a single-portion ratio is pre-fabricated in the piston cavity 9. The push rod 11 is rotatably connected to the piston body 6 by the thread, so that one end of the push rod 11 is pushed toward the cavity head, and the push rod 11 is pressed against the piston body 6. A puncture piece 8 is provided near one end of the cavity head 2. The puncture piece 8 is triangular in shape and has been strictly disinfected. When the puncture piece 8 contacts the diaphragm 7, the tip of the puncture piece 8 pierces the diaphragm 7, and the sodium heparin solution in the piston cavity 9 flows into the liquid storage tank 5, causing the sodium heparin solution to mix with the physiological saline in the liquid storage tank 5 to become a tube-sealing liquid. Since the push rod 11 is pushed to the bottom of the piston cavity 9 to form a closure, the tube-sealing liquid will not flow out from the direction of the push rod 11.

Furthermore, a push block 12 is formed at the other end of the push rod 11 , and the push block 12 is suitable for leveraging the shape of a human hand, so as to facilitate the rotation of the push rod 11 and the piston body 6 .

Furthermore, a finger gripping portion 10 is formed at one end of the cavity body 1 away from the cavity head 2. When the utility model needs to be gripped for operation, the finger gripping portion 10 is used to facilitate the doctor to grip the liquid sealing device.

Furthermore, in order to ensure that the solution in the liquid storage tank 5 does not flow out from the direction of the threaded cover 3 when the utility model is not in use, the cavity head 2 is connected to the threaded cover 3 at one end to form an external thread arranged in a circumferential direction, and the external thread is designed according to the pipe thread standard. Correspondingly, an internal thread arranged in a circumferential direction is formed in the threaded cover 3, and the internal thread is designed according to the pipe thread standard and is tightly engaged with the external thread to achieve sealing between the cavity head 2 and the threaded cover 3. After the physiological saline and the sodium heparin solution in the cavity 1 are mixed by the internal thread, the cavity head 2 and the threaded cover 3 are in a sealed state. The sealing device is shaken back and forth as a whole. When the physiological saline and the sodium heparin solution are evenly mixed, the outer wall surface of the threaded cover 3 is provided with an anti-slip strip 4 extending from the cavity head 2 to the direction of the push rod 11. The anti-slip strip 4 allows medical staff to unscrew the threaded cover 3 better due to the friction force. After unscrewing the threaded cover 3, the external thread of the cavity head 2 is connected with the internal thread of the infusion end of the butterfly needle of the infusion port, and the push rod 11 is used to push the piston body 6 toward the cavity head 2. The sealing liquid in the liquid storage tank 5 is slowly pushed out toward the cavity head due to the pressure to the infusion end of the butterfly needle of the infusion port, and the push rod 11 pushes the piston body 6 to the end of the cavity head 2 to complete the sealing operation.

The utility model is further described above with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the utility model. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the utility model.
