[0026] During the treatment, if the patient wants to go to the toilet or has other things to do, the thicker end is usually removed from the negative pressure generating device, and since the other end is still fixed to the body, the thicker end needs to be held by hand to do other things, which is not very convenient. Most importantly, interrupting the treatment in the middle may contaminate the drainage tube with the thicker end and the thinner end, and then the drainage tube needs to be replaced and the thinner end needs to be fixed again.
[0027] The utility model provides a seal assembly.
[0028] Please refer to Figure 1 In an embodiment of the utility model, the seal assembly 100 is used for sealing the end of the drainage tube, the drainage tube has a first end and a second end, the diameter of the first end is smaller than the diameter of the second end, characterized in that the seal assembly 100 comprises a first rubber plug 1 and a second rubber plug 2, the first rubber plug 1 has a first mounting cavity 11 with one end open, the first mounting cavity 11 is used for inserting the first end, the second rubber plug 2 has a second mounting cavity 21 with one end open, the second mounting cavity 21 is used for inserting one of the second end and the first rubber plug 1, and the first rubber plug 1 is at least partially inserted into the second mounting cavity 21 to accommodate the first rubber plug 1.
[0029] The utility model discloses a technical scheme through adopting setting two rubber plugs: first rubber plug 1 and second rubber plug 2, respectively to the first end part and the second end part are protected. First is the first end part, because the first end part is inserted in the course of treatment and directly contacted with the affected part, so no matter is to the inside, outside of the first end part all need to be protected, therefore, first rubber plug 1 has the first installation cavity 11 of one end opening setting, and the first installation cavity 11 is used for the first end part to insert to the first end part is covered, and the outside contact is blocked, and the risk of being contaminated is reduced. But because the first end part and the second end part are communicated, so bacteria, virus and contaminant also can go to the first end part position from the second end part, so need to block the second end part. Because the second end part is connected with negative pressure generating device, so the second end part keeps clean, and it is also necessary to protect the second end part (prevent suffering from damage, cause air leakage when connecting). Therefore, second rubber plug 2 has the second installation cavity 21 of one end opening setting, and the second installation cavity 21 is used for the second end part to insert to the second end part is covered, and the outside contact is blocked, and the risk of being contaminated is reduced. And the second end part is protected. In addition, the second installation cavity 21 can also be used for the first rubber plug 1 to insert, when the patient receives treatment, first rubber plug 1 and second rubber plug 2 need to be taken down, in order to facilitate storage, prevent rubber plug to lose and make first rubber plug 1 insert the second installation cavity 21, make first rubber plug 1 and second rubber plug 2 become one, facilitate storage, and after storage, the first installation cavity 11 and the second installation cavity 21 all do not communicate with the outside, keep clean, healthy, when using, it is taken and used immediately.
[0030] Because the first end part and the second end part need to be isolated from the outside, so the first end part and the first installation cavity 11, the second end part and the second installation cavity 21 are not gap fit and excess fit, but interference fit. Because it is interference fit, it is inconvenient for the first end part to insert the first installation cavity 11, the second end part to insert the second installation cavity 21, therefore, in an embodiment, the first installation cavity 11 includes the first main cavity 111 and the first guide cavity 112, and the first main cavity 111 and the first guide cavity 112 are sequentially arranged along the opening direction of the first rubber plug 1, and the first guide cavity 112 is expanded along the opening direction of the first rubber plug 1. And, the second installation cavity 21 includes the second main cavity 211 and the second guide cavity 212, and the second main cavity 211 and the second guide cavity 212 are sequentially arranged along the opening direction of the second rubber plug 2, and the second guide cavity 212 is expanded along the opening direction of the second rubber plug 2. Among them, the maximum opening of the first guide cavity 112 is greater than the outer diameter of the first end part, so as to facilitate the insertion of the first end part, and finally insert into the first main cavity 111 under the guidance of the first guide cavity 112, and the first end part is interference fit with the first main cavity 111. The second guide cavity 212 has the same effect as the first guide cavity 112, and is not described again.
[0031] In order to facilitate the insertion of the first plug 1 into the second installation cavity 21, the outer side wall of the first plug 1 is tapered at the end of the opening of the first installation cavity 11.
[0032] In order to prevent the first plug 1 from being separated from the second main cavity 211 and lost, the first plug 1 is in interference fit with the second main cavity 211. If the first plug 1 and the second plug 2 are plastic parts, it is difficult to separate after interference fit, and it is also difficult to fit the first plug 1 and the second plug 2. Therefore, at least one of the first plug 1 and the second plug 2 is elastically arranged and has a certain deformation and recovery ability, so as to facilitate the fitting or separation of the first plug 1 and the second plug 2.
[0033] Generally, the plug is made of harmless material to human body, which can be rubber, silica gel and other harmless materials with certain elasticity. Therefore, the first plug 1 can be a rubber first plug 1 or a silica gel first plug 1, and the second plug 2 can be a rubber second plug 2 or a silica gel second plug 2.
[0034] Since the first plug 1 is in interference fit with the second main cavity 211, some external force needs to be applied to pull out the first plug 1 from the second main cavity 211. Since the surface of the first plug 1 is relatively smooth, it is difficult to find a force point, so the outer side wall of the first plug 1 is protruding to form a protruding part 12. By applying external force to the protruding part 12, the first plug 1 can be taken out.
[0035] After the first plug 1 and the first end are installed, the second plug 2 is installed. When the second end is inserted into the second main cavity 211, the volume of the gas located in the first plug 1, the second plug 2 and the flow guide pipe is certain. If it is further inserted, the internal gas pressure becomes larger, which may cause the assembled first plug 1 and the first end to be separated under the action of gas pressure. Similarly, when the first plug 1 is inserted into the second plug 2 for storage, due to the internal gas pressure, the first plug 1 is difficult to insert into the second main cavity 211. Even if it is inserted, after the external force is removed, the first plug 1 exits the second main cavity 211 under the action of gas pressure. Therefore, in an embodiment, the second plug 2 is provided with a through hole 22 away from the opening position of the second installation cavity 21, and the through hole 22 communicates the second installation cavity 21 with the outside to balance the gas pressure and ensure successful assembly.
[0036] But due to the presence of the through hole 22, resulting in prevent pollution effect greatly discounted, further, in an embodiment, the sealing assembly 100 also includes check valve 3, the check valve 3 is arranged in the through hole 22.When the air pressure is larger check valve 3 opens, ensure that the assembly is successful, when the air pressure is smaller check valve 3 closes, isolated from the outside world, prevent the inside of the flow guide pipe from being polluted.Check valve 3 includes rubber check valve 3, rubber check valve 3 has a plurality of elastic diaphragm, a plurality of elastic diaphragm abut each other to block the through hole 22, when the air pressure is larger, a plurality of elastic diaphragm separate from each other, to balance the air pressure, when the air pressure is smaller, a plurality of elastic diaphragm restores under the action of elastic force, continue to block the through hole 22.
[0037] In the treatment process, the patient wants to go to the toilet or has other things to interrupt the treatment, generally is taken off from the negative pressure generating device second end part, since the first end part is still fixed on the body, so it is necessary to hand the second end part to do other things, it is not very convenient.So, in an embodiment, the sealing assembly 100 also includes first magic tape 4 and second magic tape 5, the first magic tape 4 and the second magic tape 5 are arranged in strip, one end of the first magic tape 4 and one end of the second magic tape are fixedly connected with the outer side wall of the second rubber plug 2.The first magic tape 4 and the second magic tape 5 are adhered to each other to fix the second rubber plug 2 on the thigh of the human body.Now the first end part and the second end part are fixed on the body, the patient's hand can be released, the patient's activity is convenient, and the transaction is handled.
[0038] In order to make the second rubber plug 2 extend synchronously with the leg, and fit on the leg, prevent the second rubber plug 2 and the drainage tube from interfering with the other leg when the second end part is connected.So in the direction towards the opening of the second rubber plug 2, the end of the first magic tape 4 for fixed connection with the second rubber plug 2 and the end of the second magic tape 5 for fixed connection with the second rubber plug 2 are equivalent in position, so that when the second rubber plug 2 is fixed on the leg, it extends in the up-down direction.
[0039] The above only for the exemplary embodiments of the present application, not therefore limit the patent range of the present application, all in the technical concept of the present application, use the present application specification and drawing contents made equivalent structure transformation, or direct / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
