[0036] The technical solutions in the embodiments of the present utility model are clearly and completely described below through specific specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific implementation manners. Without conflict, the following embodiments and the features in the embodiments can be combined with each other. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.
[0037] Figure 1 —4 shows the main technical content of this embodiment. This specific embodiment provides a protective cover for a urinary catheter 5, which includes:
[0038] The first covering part 1, the first covering part 1 includes a first covering layer 11 and a second covering layer 12. The first covering layer 11 and the second covering layer 12 have an open state and a closed state. Among them, in the closed state, a first chamber 121 is formed between the first covering layer 11 and the second covering layer 12;
[0039] The second covering part 2, which is connected to the first covering layer 11 / second covering layer 12. Among them, the second covering part 2 has a second chamber 22 and an opening 21 communicating with the second chamber 22, and the second chamber 22 communicates with the first chamber 121.
[0040] After indwelling the urinary catheter 5 for a pregnant woman, first insert the body part of the urinary catheter 5 into the second chamber 22 of the second covering part 2 through the opening 21, so that the second covering part 2 forms a covering on the body of the urinary catheter 5. Then, place the end of the urinary catheter 5 between the first covering layer 11 and the second covering layer 12 that are in an open state, and then convert the first covering layer 11 and the second covering layer 12 into a closed state. As a result, the first covering layer 11 and the second covering layer 12 form a wrapped state on the end of the urinary catheter 5, so that during the period when the pregnant woman lies in a lateral position in bed, the part of the urinary catheter 5 outside the human body will not cause hard compression on the local skin of the pregnant woman, thereby avoiding the occurrence of pressure sores.
[0041] Reference Figure 5—6, the first cladding layer 11 and the second cladding layer 12 are mirror - image settings with respect to each other. Specifically, the first cladding layer 11 has a first groove 1211, and the second cladding layer 12 has a second groove 1212. When the first cladding layer 11 and the second cladding layer 12 are in a closed state, the first groove 1211 corresponds to the second groove 1212, thereby forming a first chamber 121. Preferably, the first cladding layer 11 and the second cladding layer 12 have multiple model specifications. Among them, the first groove 1211 and the second groove 1212 are provided in multiple shapes according to different specifications of the first cladding layer 11 and the second cladding layer 12, so that when in use, the ends of catheters 5 of different models can be clad.
[0042] Reference Figure 6 —7, in this embodiment, a connecting part is provided to connect the first cladding part 1 and the second cladding part 2. The connecting part can be bent after being stressed, so that the second cladding layer 12 can move away from and close to the first cladding layer 11, and further enable the first cladding layer 11 and the second cladding layer 12 to be converted between an open state and a closed state. When in use, the first cladding layer 11 and the second cladding layer 12 are in an open state. Then, the end of the catheter 5 is placed between the first cladding layer 11 and the second cladding layer 12, and then the first cladding layer 11 and the second cladding layer 12 are converted to a closed state. Thus, the first cladding layer 11 and the second cladding layer 12 form a wrapped state around the end of the catheter 5, and further avoid the end of the catheter 5 from causing abrasions to the skin of the pregnant woman when the pregnant woman is in a side - lying position.
[0043] Reference Figure 7 , in this embodiment, the first cladding layer 11 has a first connecting member, and the second cladding layer 12 has a second connecting member. Among them, the first connecting member and the second connecting member are detachably connected to each other, so that the first cladding layer 11 and the second cladding layer 12 can be converted between an open state and a closed state. Specifically, the first cladding layer 11 has a first surface, and the second cladding layer 12 has a second surface. When in the closed state, the first surface and the second surface are in contact with each other. At this time, the first connecting member and the second connecting member form a connection relationship, and further enable the first cladding layer 11 and the second cladding layer 12 to always remain in a closed state, thereby avoiding the first cladding layer 11 and the second cladding layer 12 from unfolding during the use process.
[0044] Reference Figure 7, Specifically, the first connecting member is the hook-and-loop female patch 13, and the second connecting member is the hook-and-loop male patch 14. The hook-and-loop female patch 13 and the hook-and-loop male patch 14 are attached to each other. When in use, after placing the end of the urinary catheter 5 between the first covering layer 11 and the second covering layer 12, a connection relationship, i.e., a closed state, is formed through the mutual attachment between the hook-and-loop female patch 13 and the hook-and-loop male patch 14. Conversely, applying force to one of the first covering layer 11 and the second covering layer 12 causes the hook-and-loop female patch 13 and the hook-and-loop male patch 14 to separate from each other, and then the state between the first covering layer 11 and the second covering layer 12 is converted to an open state.
[0045] Reference Figure 1 and Figure 3 , In this embodiment, the second covering portion 2 further has a third connecting member and a fourth connecting member. The third connecting member is disposed on one side of the opening 21, and the fourth connecting member is disposed on the other side of the opening 21. The third connecting member and the fourth connecting member are detachably connected. When in use, first, the part of the tube body of the urinary catheter 5 outside the human body is inserted into the second chamber 22 of the second covering portion 2 through the opening 21, and then the third connecting member and the fourth connecting member are connected, so that the second covering portion 2 maintains a relatively tight covering force on the tube body of the urinary catheter 5, thereby preventing the urinary catheter 5 from slipping out of the second chamber 22.
[0046] Reference Figure 1 , Figure 3 and Figure 8 , Specifically, the third connecting member includes an extension section 23 disposed along one side of the opening 21. The inner side of the extension section 23 may also be provided with a hook-and-loop female patch. The fourth connecting member includes a hook-and-loop male patch disposed on the other side of the opening 21. After the hook-and-loop female patch and the hook-and-loop male patch are attached to each other, the extension section 23 can completely cover the opening 21, thereby forming a covering on the tube body of the urinary catheter 5. In this way, when the pregnant woman is in the lateral position, the pressure of the tube body of the urinary catheter 5 on the skin of the pregnant woman is reduced.
[0047] Alternatively (not shown), a first bonding layer is provided on the inner side of the extension section 23. The extension section 23 is bonded to the outer wall of the second covering portion 2 through the first bonding layer. More specifically, the first bonding layer is composed of one of a natural rubber-based adhesive and a synthetic polymer adhesive.
[0048] Reference Figure 3 —4, In this embodiment, the first covering layer 11, the second covering layer 12, and the second covering portion 2 are all made of the same material. The opening 21 of the second covering portion 2 can be enlarged when subjected to force. When in use, applying force to the opening 21 causes the width of the opening 21 to be expanded, and thus the tube body of the urinary catheter 5 is placed in the second chamber 22. Through this setting, the second covering portion 2 can more easily cover the urinary catheter 5.
[0049] Specifically, the first coating layer 11, the second coating layer 12, and the second coating portion 2 are all made of one of sponge, latex, and silica gel. Preferably, it is sponge. Specifically, the first coating layer 11, the second coating layer 12, and the second coating portion 2 all have a first flexible surface and a second flexible surface. The sponge is disposed between the first flexible surface and the second flexible surface. When in use, when a pregnant woman presses the catheter 5, the sponge deforms, that is, it is compressed, so as to play a role in slowing down the extrusion force, thereby avoiding the catheter 5 directly acting on the inner thigh of the pregnant woman, thus achieving the avoidance of the generation of pressure sores.
[0050] Alternatively (not shown), the first coating layer 11 and the second coating layer 12 both include: a first flexible outer layer, wherein a first interlayer is formed inside the first flexible outer layer. The second coating portion 2 includes a second flexible outer layer, wherein a second interlayer is formed inside the second flexible outer layer; wherein, a polymer gel is disposed in both the first interlayer and the second interlayer.
[0051] Reference Figure 2 、 Figure 5 and Figure 8 —9, in this embodiment, it further includes: a first connecting band 3 and a second connecting band 4. The second connecting band 4 can form a ring around the second coating portion 2. After the second connecting band 4 forms a ring, it can allow the second coating portion 2 to move relative to the second connecting band 4. More specifically, the length of the first connecting band 3 is greater than the length of the second connecting band 4. When in use, the first connecting band 3 is worn on the thigh of the pregnant woman, and the second connecting band 4 forms a closed ring around the second coating portion 2, so as to limit the position of the catheter 5 and avoid large-scale movement of the catheter 5. At the same time, the second connecting band 4 allows the pregnant woman to move greatly. At this time, the second coating portion 2 can move within the annular space formed by the second connecting band 4, avoiding pulling on the catheter 5 when the pregnant woman moves greatly, thus avoiding the problem of the catheter 5 slipping out of the human body.
[0052] More preferably, an attaching layer is provided on the surface of the first connecting band 3 facing away from the second connecting band 4. When in use, through the attaching layer, the first connecting band 3 is pasted on the body surface of the patient, thereby realizing the configuration of the first connecting band 3 on the body surface of the pregnant woman.
[0053] The usage method of the present utility model:
[0054] 1. After indwelling a catheter for a pregnant woman, first insert the body portion of the catheter into the second chamber of the second coating portion through the opening, and combine the third connecting member and the fourth connecting member, so that the second coating portion forms a coating on the body of the catheter;
[0055] 2. Then, place the end of the catheter between the first and second covering layers which are in an open state, and then convert the first and second covering layers into a closed state, so that the first and second covering layers form a wrapped state around the end of the catheter;
[0056] 3. Attach the first connecting band to the inner thigh of the pregnant woman, then place the second covering part on the unfolded second connecting band, and wind the second connecting band around the second covering part to form a closed loop, thereby limiting the position of the catheter.
[0057] The description of the above embodiments is only for understanding the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements can be made to the present invention, and these improvements will also fall within the protection scope of the claims of the present invention.
