Description

Technical Field

[0001] The utility model relates to the technical field of sealing covers, in particular to a sealing cover for a dialysate barrel. Background Art

[0002] Dialysate refers to a liquid that exchanges solutes with blood through diffusion on both sides of the dialysis membrane during hemodialysis. Dialysate usually contains potassium ions, sodium ions, calcium ions, magnesium ions, chloride ions, bicarbonate, etc. Since the dialysate has a certain osmotic pressure, it can also be used for peritoneal dialysis, etc. At present, medical drug manufacturers usually put the dialysate into the dialysate barrel for hospital use.

[0003] At present, when using a dialysate barrel, it is first necessary to remove the plastic cover installed at the factory, and then insert the dialysate tube. In order to prevent dust, foreign matter, etc. from entering the dialysate barrel through the gap between the barrel mouth and the dialysate tube, it is generally necessary to install a seal at the barrel mouth.

[0004] The existing sealing parts are mainly rubber sleeves, which are sleeved on the outer surface of the dialysate tube and then inserted into the barrel mouth to achieve a sealing effect. However, in order to achieve a better sealing effect, the rubber sleeve, the dialysate tube and the barrel mouth are all interference fit, so greater resistance is generated during assembly, making assembly difficult. Therefore, a dialysate barrel sealing cover is proposed. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and provides a dialysate bucket sealing cover.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a dialysate barrel sealing cover, comprising a dialysate tube, the outer surface of the dialysate tube is sleeved with a cover, the inner top of the cover is fixedly connected with a circular shell, the inner bottom of the circular shell is fixedly connected with a bamboo tube, and the bamboo tube is sleeved on the outer surface of the dialysate tube; the top of the bamboo tube is fixedly connected with an annular seat, and the annular seat is sleeved on the outer surface of the dialysate tube, the inside of the annular seat is provided with an annular cavity, and an air pushing assembly is installed between the annular cavity and the annular seat; a plurality of elastic sealing membranes are fixedly installed on the inner surface of the annular seat, and a gas supply channel is installed between the plurality of elastic sealing membranes and the annular cavity.

[0007] Furthermore, the air thrust assembly includes an annular piston, and the annular piston is in sliding contact with the annular cavity. A threaded tube is fixedly connected to the top of the annular piston, and the threaded tube passes through the top of the annular cavity and extends to the top of the annular seat and is threadedly connected to the annular seat. When the movable piston moves downward, the gas inside the annular cavity will be pressed into the air supply channel. When the annular piston moves upward, the cavity at the bottom of the annular cavity will be increased.

[0008] Furthermore, a driving ring is fixedly connected to the top of the threaded tube, and an outer surface of the driving ring is provided with anti-skid patterns. The provision of the anti-skid patterns increases the friction of the outer surface of the driving ring to avoid slipping during use.

[0009] Furthermore, the air supply channel includes two main channels, and the two main channels are symmetrically opened on the inner wall of one side of the annular cavity. The two main channels are jointly provided with a plurality of annular grooves, and the annular grooves are opened on the inner wall of the annular seat. The setting of the main channels can transport the gas inside the annular cavity to the plurality of annular grooves.

[0010] Furthermore, the plurality of elastic sealing membranes are fixedly mounted at the notches of adjacent annular grooves, and after the annular grooves are filled with gas, the elastic sealing membranes expand.

[0011] Furthermore, a through hole penetrating to the inner bottom is provided at the bottom of the circular shell, and the through hole is connected to the bamboo tube. The provision of the through hole facilitates the dialysate tube to pass through the circular shell.

[0012] Furthermore, the inner surface of the cover is provided with an internal thread, which matches the external thread of the through hole of the dialysate barrel, so that the cover can be easily assembled on the outer surface of the dialysate barrel.

[0013] Beneficial effects of the utility model:

[0014] When the utility model is in use, the dialysate barrel sealing cover replaces the original rubber sleeve structure through the provided cover, bamboo tube, circular shell, air pushing assembly, annular cavity, annular seat, air supply channel and elastic sealing film, so as to seal the gap between the barrel mouth and the dialysate tube. Meanwhile, threaded assembly is adopted, which does not generate large resistance and reduces the difficulty of assembly. Meanwhile, when the dialysate in the dialysate barrel is almost used up and it is found that the insertion length of the dialysate tube is insufficient, it only needs to be pressed down to lower the bottom opening position of the dialysate tube, thereby improving the use effect.

[0022] like Figures 1 to 3 As shown, it relates to a dialysate barrel sealing cover, including a dialysate tube 1, the outer surface of the dialysate tube 1 is sleeved with a cover 4, the inner top of the cover 4 is fixedly connected with a circular shell 5, the inner bottom of the circular shell 5 is fixedly connected with a bamboo tube 6, and the bamboo tube 6 is sleeved on the outer surface of the dialysate tube 1, and the inner surface of the cover 4 is provided with an internal thread. The bamboo tube 6 not only has a certain support, but also has a certain contraction performance when pressed.

[0023] The top of the bamboo tube 6 is fixedly connected to an annular seat 3, and the annular seat 3 is sleeved on the outer surface of the dialysate tube 1. An annular cavity 10 is opened inside the annular seat 3, and an air pushing assembly is installed between the annular cavity 10 and the annular seat 3. The air pushing assembly includes an annular piston 9, and the annular piston 9 is slidingly abutted against the annular cavity 10. The top of the annular piston 9 is fixedly connected to a threaded tube 2, and the threaded tube 2 passes through the top of the annular cavity 10 and extends to the top of the annular seat 3 and is threadedly connected to the annular seat 3. The top of the threaded tube 2 is fixedly connected to a drive ring 8, and the outer surface of the drive ring 8 is provided with anti-slip grooves. By twisting the drive ring 8, the drive ring 8 can drive the threaded tube 2 to rotate, and the threaded tube 2 and the annular seat 3 can drive the annular piston 9 to move.

[0024] A plurality of elastic sealing membranes 13 are fixedly installed on the inner surface of the annular seat 3, and a gas supply channel is installed between the plurality of elastic sealing membranes 13 and the annular cavity 10.

The two main channels 11 are jointly opened with a plurality of annular grooves 12, and the annular grooves 12 are opened on the inner wall of the annular seat 3. The plurality of elastic sealing membranes 13 are fixedly installed at the notches of adjacent annular grooves 12. When the gas in the annular cavity 10 enters the main channel 11, it is distributed to each annular groove 12. The amount of gas in the annular groove 12 increases, causing the elastic sealing membrane 13 to expand, allowing it to fit tightly against the outer wall of the dialysate tube 1, thereby ensuring the sealing performance.

[0025] A through hole 7 penetrating to the inner bottom is provided at the bottom of the circular shell 5 , and the through hole 7 is connected to the bamboo tube 6 . The provision of the through hole 7 facilitates the dialysate tube 1 to pass through the circular shell 5 .
