Description

Technical Field

[0001] This utility model belongs to the technical field of ventilator accessories, and specifically relates to a valve sealing cap and a ventilator connector. Background Technology

[0002] A ventilator connector includes a catheter with an insertion port at its end. When suctioning is not required, the insertion port is sealed with a cap. When suctioning is required, medical staff need to open the cap first before inserting the suction catheter through the insertion port into the catheter for suctioning. However, in actual use, when medical staff open the cap, secretions inside the catheter often inevitably spray out from the insertion port, causing contamination to the surrounding area.

[0003] Therefore, existing technologies need to be improved and developed. Utility Model Content

[0004] The purpose of this invention is to provide a valve sealing cap and a ventilator connector, which solves the problem of secretion splashing when using existing ventilator connectors, and achieves the effect of avoiding contamination caused by secretion splashing.

[0005] In a first aspect, the present invention provides a valve sealing cap, comprising a housing, wherein the housing is provided with a channel extending in an axial direction, and a plurality of elastic valves are arranged on the inner side of the channel around the axis of the channel, wherein the first end of all the elastic valves is fixed on the channel as a fixed end and the second end is bent inward toward the same axis of the channel as a free end to cooperate in closing the channel.

[0006] The valve sealing cap provided by this utility model utilizes the valve structure to enable the channel to conduct in one direction, thereby preventing secretions from splashing outwards and without affecting the insertion of the suction catheter, thus effectively preventing secretions from contaminating the surrounding area during suctioning.

[0007] Furthermore, each of the elastic valves is provided with a corresponding elastic component between itself and the housing. The elastic component is fixed on the channel and keeps in contact with the elastic valve. The elastic component is used to provide restorative elasticity to the elastic valve.

[0008] By improving the elasticity of the valve through elastic components, the valve can be correctly reset after repeated deformation, thereby greatly extending the overall service life of the valve sealing cap and significantly reducing the risk of secretion leakage.

[0009] Furthermore, the elastic component is provided with an arc surface, which extends along the bending direction of the elastic valve and contacts the surface of the elastic valve.

[0010] This helps prevent unpredictable deformation caused by uneven local stress on the elastic valve, thus ensuring that secretions do not leak out.

[0011] Furthermore, the axial width of the elastic member gradually widens in the radially outward direction.

[0012] This helps ensure that the elastic component is correctly reset and avoids unpredictable deformation of the elastic component in certain areas.

[0013] Furthermore, the elastic valve is made of silicone or rubber material.

[0014] Furthermore, the elastic component is made of silicone or rubber material.

[0015] Secondly, this utility model provides a ventilator connector, including the valve sealing cap described above.

[0016] Furthermore, it also includes a catheter, the end of which is provided with an insertion port, through which the valve sealing cap is inserted and connected to the catheter.

[0017] Furthermore, a sealing cap is connected to the conduit, which can cover the insertion port to close it.

[0018] Furthermore, the catheter is connected to the sealing cap via a break portion, which can break off after the sealing cap is pulled out of the insertion port.

[0019] As can be seen from the above, the valve sealing cap of this utility model includes a curved elastic valve. When secretions are sprayed outwards, all the elastic valves cooperate to close the channel, thereby preventing secretions from splashing outwards. At the same time, when the user inserts the suction tube into the channel from the outside inwards, the pressure will force the elastic valves to deform, thereby causing all the elastic valves to unfold. Therefore, it will not hinder the insertion of the suction tube into the channel, thus achieving the effect of preventing secretions from accidentally splashing out without hindering suctioning, and preventing secretions from causing pollution to the surrounding area.

[0020] Other features and advantages of this invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing embodiments of the invention. The objects and other advantages of this invention can be realized and obtained by means of the structures particularly pointed out in the written description and the accompanying drawings.

[0035] Reference Appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 5 This utility model provides a valve sealing cap, including a housing 100. The housing 100 is provided with a channel 110 extending in the axial direction. Multiple elastic valves 200 are arranged on the inner side of the channel 110 around the axis of the channel 110. The first end of all elastic valves 200 is fixed on the channel 110 as a fixed end, and the second end is bent inward toward the same axis of the channel 110 as a free end to cooperate in sealing the channel 110.

[0036] In this embodiment, the second end of the elastic valve 200 first comes into contact with the secretions. Under the impact of the secretions, all the elastic valves 200 cooperate to further contract the second end, thereby sealing the channel 110 and preventing the secretions from splashing outward through the channel 110. At the same time, when the user inserts the suction tube into the channel 110 from the first end to the second end, the suction tube compresses the elastic valves 200, causing all the elastic valves 200 to deform and open the second end, allowing the suction tube to pass smoothly through the elastic valves 200. Meanwhile, the elastic force accumulated by the elastic valves 200 also acts on the suction tube, thereby providing a certain degree of fixation for the suction tube.

[0037] In some embodiments, reference is made to the appendix. Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 Each elastic valve 200 is provided with a corresponding elastic component 300 between itself and the housing 100. The elastic component 300 is fixed on the channel 110 and keeps in contact with the elastic valve 200. The elastic component 300 is used to provide restorative elasticity to the elastic valve 200.

[0038] In practical applications, whether secretions will spray outward through channel 110 depends entirely on the sealing degree of the elastic valve 200 to channel 110. In practical applications, the suction catheter may be repeatedly inserted and withdrawn, causing the elastic valve 200 to lose elasticity and fail to reset correctly, thereby reducing the sealing performance of the elastic valve 200 to channel 110 and leading to the problem of accidental leakage of secretions. To address this, this embodiment improves the elasticity of the elastic valve 200 through the elastic component 300, thereby ensuring that the elastic valve 200 can still reset correctly after multiple deformations, thus greatly improving the overall service life of the valve sealing cap and significantly reducing the risk of secretion leakage.

[0039] In some embodiments, reference is made to the appendix. Figure 1 and attached Figure 3 The elastic component 300 is provided with an arc surface 310, which extends along the bending direction of the elastic valve 200 and contacts the surface of the elastic valve 200. Surface contact is more conducive to the correct reset of the elastic valve 200 and avoids unpredictable deformation caused by uneven local stress on the elastic valve 200, thereby helping to ensure that secretions do not leak out.

[0040] In some embodiments, reference is made to the appendix. Figure 3 and attached Figure 4The axial width of the elastic component 300 gradually widens in the radial outward direction. When the elastic component 300 is stretched or contracted by the force of the elastic valve 200, this gradually changing width shape can better transmit the force evenly to both sides of the elastic component 300 in the width direction, thereby causing equal deformation on both sides of the elastic component 300 in the width direction. This helps to ensure that the elastic component 300 is correctly reset and avoids unpredictable deformation of the elastic component 300 in some areas.

[0041] In some embodiments, the elastic valve 200 is made of silicone or rubber material.

[0042] In some embodiments, the elastic member 300 is made of silicone or rubber material.

[0043] Reference Appendix Figure 6 and attached Figure 7 This utility model provides a ventilator connector, including the valve sealing cap in the above embodiment.

[0044] In some embodiments, reference is made to the appendix. Figure 7 The ventilator connector also includes a catheter 400, with a socket 410 at the end of the catheter 400. The valve sealing cap is connected to the catheter 400 through the socket 410. The valve sealing cap is installed on the catheter 400 in a detachable manner, which is beneficial for replacing the valve sealing cap when it is found to be damaged, without having to scrap the entire ventilator connector.

[0045] In some embodiments, reference is made to the appendix. Figure 6 and attached Figure 7 The catheter 400 is connected to a sealing cap 420, which can be closed on the inlet 410. When the ventilator connector is not unsealed, the sealing cap 420 can completely block the inlet 410, thereby preventing contamination caused by dust and other particles entering the catheter 400. (Compared to the valve sealing cap, since there are inevitably gaps between the multiple elastic valves 200, dust and other particles still have the risk of entering the catheter 400. Therefore, the valve sealing cap is only suitable for preventing the leakage of secretions and other mucus. In actual application, the catheter 400 must still be sealed with the sealing cap 420.)

[0046] In some embodiments, reference is made to the appendix. Figure 6 and attached Figure 7The catheter 400 is connected to the sealing cap 420 via a break portion 430. The break portion 430 can break after the sealing cap 420 is pulled out of the insertion port 410. The break portion 430 can be a thin wire made of elastic material. When the user pulls the sealing cap 420 out of the insertion port 410, the thin wire will break. Therefore, whether the ventilator connector has been used can be determined by whether the thin wire is broken, thereby ensuring the safe use of the ventilator connector. In addition, the break portion 430 can also be a disposable connector made of brittle material.

[0047] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0048] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
