Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to a detection device for cervical opening and its installation method. Background Art

[0002] At present, the cervical opening during pregnant women's delivery is checked by artificial fingers. Since the finger sizes of different doctors are different, the detected results are also different. At the same time, doctors often need to check frequently before childbirth, which will cause a very poor experience for pregnant women, and will also increase the pain and infection probability of pregnant women. Therefore, inventing an accurate prenatal detection instrument to replace manual finger examination has become the research direction in this field.

[0003] For example, the Chinese patent with the patent number CN202211239837.2 discloses a prenatal detection instrument and a detection system, which can be used to replace finger examination of the cervical opening and other situations. However, when fixing the detection instrument in the body, the existing patent adopts the method of cutting a disposable connecting tube. Specifically, the outer adsorption layer of the existing patent is connected with a connecting tube communicating with the contraction space. The connecting tube is the connecting end of the detection instrument. The negative pressure device is connected through the connecting tube, and the air in the contraction space is sucked out through the connecting tube and the negative pressure device, so that the detection instrument is fixed on the inner wall of the vagina through the adsorption holes. When this detection instrument needs to be removed, the connecting tube is cut, and the detection instrument naturally falls off. In the above solution, the connecting tube is a fragile hose with a short service life, there is a risk that the detection instrument cannot be fixed after being damaged, and the detection head cannot be quickly installed into the body. On the other hand, the connecting tube is a disposable component, resulting in a high cost.

[0004] Therefore, those skilled in the art are committed to developing a detection device for cervical opening and its installation method that can shorten the length of the connecting end and reduce the cost. Summary of the Invention

[0005] In view of the above-mentioned defects of the prior art, the present invention discloses a detection device for cervical opening and its installation method that can shorten the length of the connecting end and reduce the cost.

[0006] To achieve the above object, the present invention provides a detection device for cervical opening, including a housing, on which adsorption holes are provided. One end of the housing is connected with a transparent cover, and the other end of the housing is closely connected with a bottom shell. An integral connecting end is formed on the bottom shell. A one-way sealing structure is provided inside the connecting end, and a contact seal is provided outside the connecting end. The connecting end can be connected with a negative pressure aspirator through a rigid tube, and the detection device is adsorbed on the inner wall of the vagina by pumping negative pressure.

[0007] Preferably, the one-way sealing structure is in a normally closed state to ensure tightness; only when evacuating air from the inside of the housing through the connection end to create a negative pressure inside the detection device, the one-way sealing structure is in an open state. That is, only air can be evacuated from the detection device, and no air can be inflated into the detection device.

[0008] Preferably, the one-way sealing structure includes a sealing ball. On both sides of the sealing ball, there are respectively an annular seal and an elastic member. The annular seal is located on the side close to the housing. Both ends of the one-way sealing structure are restricted within the connection end, and the elastic member is compressed. The elastic force of the elastic member causes the sealing ball to contact the annular seal, forming a seal when the one-way sealing structure is in a normally closed state. When it is necessary to create a negative pressure inside the detection device, air is evacuated from the detection device, and the elastic member is further compressed by the sealing ball, thereby releasing the seal and completing the air evacuation.

[0009] Preferably, a through hole is provided on the inner side of the connection end. On the inner wall of the through hole, there are a first stepped hole and a second stepped hole. The diameter of the through hole is smaller than the diameter of the first stepped hole, and the diameter of the first stepped hole is smaller than the diameter of the second stepped hole; a cylindrical plug is connected inside the second stepped hole. A through hole runs through the middle of the cylindrical plug, and the one-way sealing structure is installed between the first stepped hole and the cylindrical plug.

[0010] Preferably, the annular seal is installed inside the cylindrical plug, and the outer diameter of the annular seal is larger than the diameter of the through hole in the middle of the cylindrical plug. One end of the elastic member abuts against the first stepped hole, and the other end of the elastic member abuts against the sealing ball. The elastic member can be a spring, and the outer diameter of the spring is larger than the diameter of the through hole. Of course, the first stepped hole and the second stepped hole can also be arranged in reverse, and at the same time, the cylindrical plug is installed at the end of the connection end away from the housing, the annular seal is installed in the through hole, and the spring abuts against the cylindrical plug.

[0011] Preferably, an annular groove is provided on the outer side of the connection end, and the contact seal is installed in the annular groove.

[0012] Preferably, the contact seal is an O-ring.

[0013] The present invention also provides an installation method for a detection device of a cervical opening. Install the detection device as described above, including the following steps:

[0014] 1) Provide an installation device for the detection device, including a handle for holding. One end of the handle is connected to a rigid outer tube for supporting the detection head. Inside the outer tube and the handle, there is a movable inner tube; the other end of the handle is connected to a control member for controlling the movement of the inner tube; one end of the inner tube is in contact sealing with the contact seal, and the other end of the inner tube is hermetically connected to a negative pressure aspirator.

[0015] 2) Use the negative pressure aspirator to extract the air inside the detection device, so that the detection device is adsorbed on the inner wall of the vagina;

[0016] 3) Move the inner tube to separate the inner tube from the detection device, and then pull out the installation device.

[0017] Specifically, the handle is for the operator to hold and to support the outer tube and the inner tube, facilitating the operator's use. The outer tube is used to support the detection device, and when the inner tube contacts the connector of the detection device, a sealing effect is achieved. After the inner tube is hermetically connected to the detection device, the inner tube inputs negative pressure into the detection device, fixing the detection device inside the birth canal. The connection between the inner tube and the detection device can be separated by moving the inner tube, and the movement of the inner tube is realized by rotating the control part, which can be achieved by using a threaded structure and will not be elaborated here. After separation, the negative pressure disappears, the detection device is separated from the inner tube, and then the installation device can be taken out.

[0018] In the above method embodiments, through the installation device, the handle is convenient for the operator to use and has reliable force application. The outer tube can stably support the detection head. Compared with directly taking it with an artificial finger, the risk of infection during operation is avoided. At the same time, the length of the outer tube can be designed in advance to ensure the accurate placement position.

[0019] The beneficial effects of the present invention are:

[0020] By integrally forming a connection end on the housing and arranging a one-way sealing structure inside the connection end, the connection end can be detachably connected to the tube of the installation device. That is, when negative pressure needs to be pumped, the connection end contacts and seals with the installation device. After the detection device is adsorbed on the inner wall of the vagina, the connection end is separated from the installation device. After separation, the negative pressure disappears, the detection head can be detached, and then the installation device can be taken out. Compared with the connecting tube of the existing patent, the length of the connection end is greatly shortened, and the installation device can be reused, reducing the one-time consumption of auxiliary materials and greatly reducing the cost.

[0028] The present invention will be further described below in conjunction with the drawings and embodiments. It should be noted that in the description of the present invention, the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific manner, and therefore should not be construed as a limitation to the present invention. The terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0029] As Figures 1 to 3 shown, the present invention provides a detection device 1 for the cervical opening, including a housing 11, an adsorption hole is provided on the housing 11, one end of the housing 11 is connected with a transparent cover 12, the other end of the housing 11 is closely connected with a bottom shell 13, and a connection end 14 is integrally formed on the bottom shell 13. At the same time, a one-way sealing structure 15 is provided inside the connection end 14, and a contact seal 16 is provided outside the connection end 14. Specifically, an annular groove 144 is provided outside the connection end 14, and the contact seal 16 is installed in the annular groove 144. In this embodiment, the contact seal 16 is an O-ring. The connection end 14 can be connected to a negative pressure aspirator through a rigid tube, and the detection device 1 is adsorbed on the inner wall of the vagina by pumping negative pressure. Specifically, the one-way sealing structure 15 is in a normally closed state to ensure airtightness; only when air is pumped out from the housing 11 through the connection end 14 to form a negative pressure inside the detection device 1, the one-way sealing structure 15 is in an open state. That is, air can only be pumped out from the detection device 1 and cannot be inflated into the detection device 1.

[0030] In the above embodiments, by integrally forming the connection end 14 on the housing 11 and providing a one-way sealing structure 15 inside the connection end 14, the connection end 14 can be detachably connected to the tube of the installation device 2. That is, when negative pressure needs to be pumped, the connection end 14 contacts and seals with the installation device 2. After the detection device 1 is adsorbed to the inner wall of the vagina, the connection end 14 is separated from the installation device 2. After separation, the negative pressure disappears, the detection head can be disengaged, and then the installation device 2 can be taken out. Compared with the connecting tube of the existing patent, the length of the connection end 14 is greatly shortened, and the installation device 2 can be reused, reducing the one-time consumption of auxiliary materials and greatly reducing the cost.

[0031] As Figure 3 shown, the one-way sealing structure 15 includes a sealing ball 151. On both sides of the sealing ball 151, there are respectively provided an annular seal 152 and an elastic member 153. The annular seal 152 is located on the side close to the housing 11. Both ends of the one-way sealing structure 15 are restricted within the connection end 14, and the elastic member 153 is compressed. The elastic force of the elastic member 153 causes the sealing ball 151 to contact the annular seal 152, forming a seal when the one-way sealing structure 15 is in a normally closed state. When it is necessary to form a negative pressure inside the detection device 1, air is pumped out from the detection device 1, and the elastic member 153 is further compressed by the sealing ball 151, thereby releasing the seal and completing the air pumping. To facilitate the installation of the one-way sealing structure 15, a through hole 143 is provided inside the connection end 14. The inner wall of the through hole 143 is provided with a first stepped hole 141 and a second stepped hole 142. The diameter of the through hole 143 is smaller than the diameter of the first stepped hole 141, and the diameter of the first stepped hole 141 is smaller than the diameter of the second stepped hole 142. A cylindrical plug 154 is connected inside the second stepped hole 142. A through hole is provided in the middle of the cylindrical plug 154. The one-way sealing structure 15 is installed in the space between the first stepped hole 141 and the cylindrical plug 154. In this embodiment, the annular seal 152 is installed inside the cylindrical plug 154, and the outer diameter of the annular seal 152 is larger than the diameter of the through hole in the middle of the cylindrical plug 154. One end of the elastic member 153 abuts against the first stepped hole 141, and the other end of the elastic member 153 abuts against the sealing ball 151. The elastic member 153 can be a spring, and the outer diameter of the spring is larger than the diameter of the through hole 143. Of course, the first stepped hole 141 and the second stepped hole 142 can also be arranged in reverse, and at the same time, the cylindrical plug 154 is installed at the end of the connection end 14 away from the housing 11, the annular seal 152 is installed in the through hole 143, and the spring abuts against the cylindrical plug 154.

[0032] The present invention also provides an installation method for a detection device of a cervical opening, for installing the detection device 1 as above, including the following steps:

[0033] 1) Provide a as Figure 4The installation device 2 of the detection device 1 shown includes a handle 23 for holding. One end of the handle 23 is connected to a rigid outer tube 21 for supporting the detection head. A movable inner tube 22 is provided inside the outer tube 21 and the handle 23. The other end of the handle 23 is connected to a control member 24 for controlling the movement of the inner tube 22. One end of the inner tube 22 is in contact sealing with the contact seal 16, and the other end of the inner tube 22 is sealingly connected to the negative pressure aspirator.

[0034] 2) Use a negative pressure aspirator to extract the air inside the detection device 1, so that the detection device 1 is adsorbed on the inner wall of the vagina;

[0035] 3) Move the inner tube 22 to disconnect the inner tube 22 from the detection device 1, and then pull out the installation device 2.

[0036] Specifically, the handle 23 is used for the operator to hold and for supporting the outer tube 21 and the inner tube 22, which is convenient for the operator to use. The outer tube 21 is used to support the detection device 1. When the inner tube 22 contacts the connection head of the detection device, a sealing effect is achieved. After the inner tube 22 is sealingly connected to the detection device, the inner tube 22 inputs negative pressure into the detection device, so that the detection device is fixed inside the birth canal. The connection between the inner tube 22 and the detection device can be separated by the movement of the inner tube 22. The movement of the inner tube 22 is realized by rotating the control member 24, and a threaded structure can be used, which will not be elaborated here. After separation, the negative pressure disappears, the detection device is separated from the inner tube 22, and then the installation device 2 can be taken out.

[0037] In the above method embodiments, through the installation device 2, the handle 23 is convenient for the operator to use and has reliable force application. The outer tube 21 can stably support the detection head. Compared with directly taking it with a human finger, it avoids the risk of infection during operation. At the same time, the length of the outer tube 21 can be designed in advance to ensure the accurate placement position.
