Description

Technical Field

[0001] The invention relates to the technical field of peritoneal dialysis, in particular to a hose structure for peritoneal dialysis. Background Art

[0002] Peritoneal dialysis involves regularly and regularly infusing prepared dialysate into the patient's peritoneal cavity via a catheter. The difference in solute concentration gradient on both sides of the peritoneum is used to move solutes on the high-concentration side to the low-concentration side (diffusion), while water moves from the hypotonic side to the hypertonic side (osmosis). By continuously replacing the peritoneal dialysate, the body's metabolic products and toxic substances can be removed and water and electrolyte imbalances can be corrected.

[0003] During peritoneal dialysis, a dialysis hose is required for the transportation and discharge of liquids. The dialysis hose mainly consists of a puncture cannula and a blood circuit tube. When the puncture cannula is in use, one end of the cannula is inserted and retained in the patient's body, and the other end is connected to a connector and installed and connected to the blood circuit tube through a conical joint on the connector. When the conical joint on the connector is not installed and connected to the blood circuit tube, a protective cap is connected to the end of the conical joint by a threaded manner to seal the connector, and the end of the conical joint is abutted against the disinfectant absorbed by the inner side of the protective cover. During the sealing and disinfection process of this structure, firstly, the threaded connection method is difficult to maintain sufficient sealing protection for the conical joint. Secondly, after the protective cover is removed during use, the disinfectant on the inner side of the protective cover will have a long-term contact with the air, which reduces the disinfection effect and is not convenient for the continuous covering and disinfection of the protective cover, resulting in a certain waste of resources.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figure 1-Figure 12 , a hose structure for peritoneal dialysis shown in the figure includes a soft cannula 101 and a connector 102 fixed to one end of the soft cannula 101, and a conical connector 103 for auxiliary connection is fixed to one end of the connector 102;

[0035] It should be noted that the soft cannula 101, the connector 102 and the conical connector 103 are common components of the dialysis hose, and are considered as the prior art in this application, and will not be elaborated on in detail.

[0036] Also includes:

[0037] A blocking disk 2 is used to block the end of the conical joint 103. Both sides of the conical joint 103 are provided with connection components for connecting the blocking disk 2. The blocking disk 2 is provided with a sealing component for blocking and sealing the inner side of the conical joint 103 and a disinfection component for detoxifying the end of the conical joint 103;

[0038] The sealing assembly includes a sealing plug 702, the sealing plug 702 is connected and fixed to the sealing disk 2 via a connecting column 701, and the sealing disk 2, the connecting column 701 and the sealing plug 702 are concentrically arranged, an annular mounting groove 703 is provided on the outer side of the sealing plug 702, an annular airbag 704 is provided inside the annular mounting groove 703 for sealing against the inner side of the conical joint 103, and a plurality of inflatable components for inflating the inside of the annular airbag 704 are provided on the sealing plug 702;

[0039] It is worth noting here that: before the annular airbag 704 is inflated, the interior of the annular airbag 704 is filled with gas, so that it can expand more efficiently and sensitively during the subsequent inflation process;

[0040] The disinfection component includes a liquid storage cylinder 901 fixed on the blocking plate 2, the interior of the liquid storage cylinder 901 is filled with disinfectant iodine liquid, and one side of the blocking plate 2 is provided with multiple groups of liquid outlet holes 902 communicating with the interior of the liquid storage cylinder 901, and each group of liquid outlet holes 902 is respectively installed with a liquid storage sponge 903 and a one-way valve 904, the liquid storage sponge 903 is arranged close to the outside of the liquid outlet hole 902, and the conducting direction of the one-way valve 904 is from the inside of the liquid storage cylinder 901 to the outside of the liquid outlet hole 902;

[0041] It is worth noting that: when the liquid outlet 902 is not blocked, part of the liquid storage sponge 903 is located outside the liquid outlet 902, so as to facilitate contact with the end of the conical connector 103 during the subsequent disinfection process;

[0042] The inside of the liquid storage cylinder 901 is slidably connected with a piston plate 905 for liquid extrusion, and the liquid storage cylinder 901 is provided with a pushing component for pushing the piston plate 905. One side of the blocking disk 2 is provided with a blocking component for blocking each group of liquid outlet holes 902. Each group of blocking components is respectively arranged in one-to-one correspondence with each group of inflation components, and a transmission component for transmitting the inflation component is provided on the blocking component;

[0043] It should be noted here that after dialysis treatment by peritoneal dialysis using a dialysis hose, the conical joint 103 on the connector 102 is blocked by the blocking disk 2. During the blocking process, the inflation component and disinfection are used to ensure that the inner side of the conical joint 103 is fully blocked, while the end of the conical joint 103 is disinfected. After the blocking and disinfection, the blocking component is used to prevent the disinfectant iodine solution from being ineffective and evaporating due to long-term contact with the air, which is convenient for subsequent disinfection and use.

[0044] See also Figure 7 , Fig.11 and Fig.12 The blocking assembly includes a blocking plate 1101 that abuts against one side of the blocking disk 2 for blocking the liquid outlet 902. A telescopic assembly for assisting the telescopic connection of the blocking plate 1101 is provided on one side of the blocking disk 2. The blocking plate 1101 is provided with an inclined surface 1102 for abutting against the inner side of the conical joint 103 for transmission.

[0045] It should be noted here that: when the conical joint 103 needs to be connected and used again, the sealing disk 2 is pulled to separate it from the conical joint 103. During the separation process, the inclined surface 1102 on the sealing plate 1101 no longer abuts against the inner wall of the liquid outlet 902. At this time, the elastic force of the first spring 1204 on the telescopic assembly pushes the sealing plate 1101 to reset the sealing plate 1101 and seal the liquid outlet 902 again. Through the sealing effect, the disinfectant iodine liquid adsorbed on the liquid storage sponge 903 is in a sealed state, thereby preventing the disinfectant iodine liquid from failing and evaporating due to long-term contact with air.

[0046] See also Figure 5 , Figure 6 , Fig.11 and Fig.12The inflation component includes a piston tube 801 fixed on the sealing plug 702, one end of the piston tube 801 is connected to the inside of the annular airbag 704, and a piston rod 802 is slidably connected to the piston tube 801; the transmission component includes two groups of transmission plates 1301 fixed to one side of the blocking plate 1101, the piston rod 802 is located between the two groups of transmission plates 1301, the two groups of transmission plates 1301 are provided with inclined grooves 1302, and the two groups of inclined grooves 1302 are slidably connected with transmission pins 1303, and one end of the two groups of transmission pins 1303 is respectively fixed to the two sides of the piston rod 802;

[0047] It should be noted here that: during the contraction movement of the sealing plate 1101, the interaction between the inclined groove 1302 on the transmission plate 1301 and the transmission pin 1303 drives the piston rod 802 to move toward the interior of the piston tube 801. During the movement, part of the gas inside the piston tube 801 is pushed into the interior of the annular airbag 704 to inflate the interior of the annular airbag 704.

[0048] See also Fig.12 The telescopic assembly includes a strip seat 1201 fixed to one side of the blocking plate 1101, and a plurality of first sleeves 1202 are fixed to the strip seat 1201. The first sleeves 1202 are slidably connected with first slide bars 1203. One end of the first slide bar 1203 is fixed to the outer side of the connecting column 701, and the outer side of each group of first sleeves 1202 is sleeved with a first spring 1204;

[0049] It should be noted here that: through the interaction between each group of first sleeves 1202 and first slide rods 1203 between the strip seat 1201 and the connecting column 701, the extension and retraction guidance of the blocking plate 1101 after being stressed is facilitated, and through each group of first springs 1204, the blocking plate 1101 is easily reset after the contraction movement.

[0050] See also Fig. 9 The pushing assembly includes a threaded tube 1001 rotatably connected to the liquid storage cylinder 901, one end of the threaded tube 1001 is threadedly engaged with a threaded rod 1002, one end of the threaded rod 1002 is fixed to the piston plate 905, the other end of the threaded tube 1001 is located outside the liquid storage cylinder 901 and is fixed with a driving pin 1003, two groups of second sleeves 1004 are fixed inside the liquid storage cylinder 901, the two groups of second sleeves 1004 are symmetrically arranged on both sides of the threaded tube 1001, and the two groups of second sleeves 1004 are slidably connected to the second slide rod 1005, and one end of the second slide rod 1005 is fixed to the piston plate 905;

[0051] It should be noted here that: the threaded tube 1001 is driven to rotate by the driving pin 1003. During the rotation of the threaded tube 1001, the piston plate 905 is pushed to move through the mutual meshing transmission between the threaded tube 1001 and the threaded rod 1002 and the sliding guiding effect of the second sleeve 1004 and the second sliding rod 1005.

[0052] See also Figure 3 The connection assembly includes a mounting seat 301, a mounting assembly for assisting the detachable mounting of the mounting seat 301 is arranged on the outer side of the mounting seat 301 and the conical joint 103, a connecting plate 302 is arranged on the outer side of the blocking disk 2, an elastic assembly for assisting elastic connection is arranged between the mounting seat 301 and the connecting plate 302, and a rotating assembly for assisting the rotatable connection of the blocking disk 2 is arranged between the connecting plate 302 and the outer side of the blocking disk 2;

[0053] It should be noted here that: the connection between the sealing disk 2 and the conical joint 103 is maintained by the mounting seat 301 and the connecting plate 302, thereby avoiding the risk of the sealing disk 2 being lost.

[0054] See also Figure 3 The elastic component includes a plurality of groups of third sleeves 401 fixed on the mounting seat 301, a third slide bar 402 is slidably connected to the third sleeve 401, one end of the third slide bar 402 is fixed to the connecting plate 302, and a second spring 403 is sleeved on the outer side of each group of third sleeves 401, and the two ends of the second spring 403 are respectively connected to the mounting seat 301 and the connecting plate 302;

[0055] It should be noted here that: in the process of pulling the sealing disk 2, through the connection between the rotating assembly and the connecting plate 302, each group of third sliding rods 402 is driven to slide on each group of third sleeves 401 respectively, and the second spring 403 is deformed by force to generate elastic force. Through the elastic force of the second spring 403, it is convenient to pull the sealing disk 2 to maintain a state of resistance with the conical joint 103.

[0056] See also Figure 4 The rotating assembly includes an annular groove 601 formed on the outer side of the blocking disk 2, an annular plate 602 is rotatably connected to the annular groove 601, and the connecting plate 302 is fixed on the outer side of the annular plate 602;

[0057] It should be noted here that: through the rotation of the annular groove 601 and the annular plate 602, the sealing disk 2 can be rotated while maintaining the connection with the sealing disk 2.

[0058] See also Figure 2 and Figure 3The mounting assembly includes a sliding hole 501 formed on the mounting seat 301, a bolt 502 is slidably connected to the sliding hole 501, and a threaded hole 503 for threaded connection with the bolt 502 is formed on the outer side of the conical joint 103;

[0059] It should be noted here that the threaded connection between the bolt 502 and the threaded hole 503 facilitates the detachable installation between the mounting seat 301 and the conical joint 103, and further facilitates more flexible operation and use of the entire structure.

[0060] In this scheme: a hose structure for peritoneal dialysis includes the following steps:

[0061] During the peritoneal dialysis treatment of renal disease, one end of the soft cannula 101 is inserted into the abdomen of the patient, and the conical joint 103 on the connector 102 is installed and connected with the blood circuit tube to draw blood from the patient's body, purify it through the dialyzer, and then send the blood purified by the dialyzer back to the patient's body. After dialysis, the blood circuit tube is disassembled from the end of the conical joint 103. After the disassembly is completed, the conical joint 103 is sealed and disinfected by the disinfection component and the sealing component;

[0062] In the process of sealing and disinfecting the conical joint 103, the piston plate 905 is moved toward each group of liquid outlet holes 902 in the liquid storage cylinder 901 by pushing the assembly. During the movement, the disinfectant iodine liquid in the liquid storage cylinder 901 is squeezed. During the squeezing process, under the action of the internal pressure of the liquid storage cylinder 901, the disinfectant iodine liquid passes through the one-way valve 904 of the liquid outlet hole 902 and is adsorbed on the liquid storage sponge 903. Due to the blocking effect of the sealing plate 1101 on the liquid outlet hole 902 at this time, the disinfectant iodine liquid sucked on the liquid storage sponge 903 does not overflow. After the flushing of the disinfectant iodine liquid is completed, the sealing plate 2 is pulled away from the conical joint 103. The sealing plate 2 is moved by the elastic component, and during the pulling process, the second spring 403 on the elastic component is deformed by the force to generate elastic force. After the sealing plate 2 is pulled, the sealing plate 2 is moved so that it is directly in front of the conical joint 103. At this time, the elastic pulling effect of the elastic component on the sealing plate 2 causes the sealing plate 2 to move toward the front end of the conical joint 103 and finally causes one side of the sealing plate 2 to abut against the end of the conical joint 103. During the movement of the sealing plate 2, the connecting effect of the connecting column 701 causes the sealing plug 702 to be inserted into the inner side of the conical joint 103. During the movement of the sealing plate 2, the inclined surfaces 1102 on each group of sealing plates 1101 are aligned with the conical joint 103. The inner hole of the plugging plate 1101 is offset against each other, driving each group of the blocking plates 1101 to be forced to contract toward the connecting column 701. During the contraction of the blocking plates 1101, the interaction between the inclined groove 1302 on the transmission plate 1301 and the transmission pin 1303 drives the piston rod 802 to move toward the inside of the piston tube 801. During the movement, part of the gas inside the piston tube 801 is pushed into the inside of the annular airbag 704 to inflate the inside of the annular airbag 704. After the annular airbag 704 is inflated, it expands under the pressure inside the annular airbag 704 and tightly contacts the inner wall of the conical joint 103, thereby ensuring the covering and sealing effect of the conical joint 103. During the process of the group sealing plate 1101 being forced to contract against the connecting column 701, the sealing plate 1101 no longer blocks the liquid outlet 902, and as the sealing disk 2 moves closer, the liquid storage sponge 903 on the liquid outlet 902 abuts against the end of the conical joint 103. After the sealing disk 2 abuts against the end of the conical joint 103, the sealing disk 2 is rotated. During the rotation, the liquid storage sponge 903 abuts against the end of the conical joint 103, and the disinfectant iodine liquid adsorbed on the liquid storage sponge 903 is coated on the end of the conical joint 103 through the abutting and squeezing effect, so that the end of the conical joint 103 is disinfected, which is convenient for the subsequent connection and use of the hose structure;

[0063] When the conical joint 103 needs to be connected and used again, the sealing disk 2 is pulled to separate it from the conical joint 103. During the separation process, the inclined surface 1102 on the sealing plate 1101 no longer abuts against the inner wall of the liquid outlet 902. At this time, the elastic force of the first spring 1204 on the telescopic assembly pushes the sealing plate 1101 to reset the sealing plate 1101 and seal the liquid outlet 902 again. Through the sealing effect, the disinfectant iodine liquid adsorbed on the liquid storage sponge 903 is in a sealed state, avoiding the disinfectant iodine liquid from being in contact with the air for a long time and causing failure and evaporation, which is convenient for subsequent disinfection and use, reducing resource waste, and during the resetting process of the sealing plate 1101, the piston rod 802 is reset through transmission and the interior of the annular airbag 704 is no longer inflated, avoiding the annular airbag 704 being in a high-pressure expansion state for a long time, affecting the subsequent telescopic effect of the annular airbag 704.
