Description

Technical Field

[0001] The invention relates to the technical field of nasal breathing assistance, in particular to a nasal breathing assistance device after pituitary tumor surgery. Background Art

[0002] The treatment of pituitary tumors mainly includes surgery, drugs and radiotherapy. At present, the treatment of pituitary tumors is still mainly surgery, supplemented by drugs and radiotherapy. The current surgical method is through the transsphenoidal pituitary tumor resection, which is through the nasal cavity, cutting the nasal mucosa, reaching the sellar floor bone, and then removing part of the bone, and then cutting the dura mater on the surface of the tumor, and then removing the tumor. After the operation is completed, it is necessary to fill the residual tumor cavity with hemostatic material, and then reposition the cut nasal mucosa, and then add packing to fill the nasal cavity, and press the opened mucosa to stop bleeding. However, during the compression process, these packings will affect the patient's breathing, and then these breathing assistance devices are needed to ensure that the patient can breathe normally through the nasal cavity.

[0003] The existing authorization publication number is "CN215306362U", which is a nasal packing device for postoperative pituitary tumor surgery, including a packing and a delivery mechanism for delivering the packing, wherein the packing includes an oxygen tube and a compression structure arranged outside the oxygen tube; the compression structure is used to compress the inside of the nasal cavity to stop bleeding. The compression structure includes a plurality of small holes opened on the wall of the oxygen tube, an air bag arranged outside the small holes, and hemostatic cotton arranged at the end of the air bag away from the oxygen tube. The air bag of the packing can better fill the nostrils. The propulsion mechanism can continuously push the packing out of the filling chamber and then fill it into the nasal cavity, which can greatly reduce the workload of manual labor.

[0004] During the treatment process, the device needs to be placed in the patient's nasal cavity for a long time. During the process of hemostasis and treatment, the device directly blocks the inside of the patient's nasal cavity, causing the filled nasal cavity to be unable to breathe, which in turn affects the patient's comfort. At the same time, the inside of the nasal cavity may also secrete liquid, and some patients will have symptoms of rhinorrhoea. Then these exudates will leak along the device to the outside, causing the bed sheets and the patient's clothes to be contaminated. Summary of the invention

[0029] After the operation, first insert the plug 8 and the connecting tube 9 into the patient's nasal cavity. After the insertion, fix the device to the patient's nasal cavity with a bandage or medical tape to prevent it from falling. During the insertion process, the medical sponge 6 can press the position of the patient's wound after suture, thereby stopping the bleeding, and the liquid medicine inside the medical sponge 6 can also accelerate the patient's healing, and under the action of the airbag 7, the shape of the medical sponge 6 is effectively maintained, thereby improving the effect of the medical sponge 6 on compressing the wound. During the patient's breathing, air can pass through the middle position of the medical sponge 6, thereby preventing the patient's breathing from being affected.

[0030] After surgery, general devices will affect the patient's breathing, but this device can assist the patient's breathing during use, and will not affect the patient's breathing while treating the patient's surgical wound, thereby improving the patient's comfort during treatment. The medical sponge 6 can absorb the medicine so that the medicine can treat the patient's wound for a long time. At the same time, through the action of the airbag 7, the middle of the medical sponge 6 can be opened to facilitate air circulation, and the strength of the medical sponge 6 can be improved to prevent the deformation of the medical sponge 6 from affecting the compression of the wound.

[0031] Installation grooves are symmetrically provided on both sides of the plug 8, and the medical sponge 6 is located inside the installation groove, so that one side of the medical sponge 6 can extend to the outside of the device, so that the medical sponge 6 can press the wound position of the patient to stop bleeding, and the liquid medicine inside the medical sponge 6 can also accelerate the healing of the patient's wound. An installation cavity is provided inside the medical sponge 6, and the airbag 7 is located inside the installation cavity, so that the airbag 7 can be installed inside the medical sponge 6, thereby improving the strength of the medical sponge 6.

[0032] A plurality of mounting holes are provided at the mounting plate 1, which facilitate the insertion of wires into the interior. At the same time, the wires bind the device to the patient's head, which facilitates the fixation of the device. A mounting sleeve is provided at the bottom of the mounting plate 1, and the air inlet pipe 2 and the connecting ring 3 are both located inside the mounting sleeve, which facilitates the installation of the air inlet pipe 2.

[0033] The top of the plug 8 is made of soft rubber material, and the top of the plug 8 is tapered, so that the device can be easily inserted into the patient's nasal cavity, and during the insertion process, the soft material can avoid causing damage to the patient's nasal cavity.

[0034] Embodiment 2

[0035] See also Figure 2 and Figure 4 , further changes were made on the basis of Example 1:

[0036] The guide assembly 4 includes a connecting pipe 41, a support rod 42, an annular guide ramp 43, a guide baffle 44 and a hose 45. The annular guide ramp 43 is located at the bottom of the inner side of the connecting pipe 9. The connecting pipes 41 are symmetrically arranged on both sides of the bottom of the annular guide ramp 43 to facilitate the circulation of the seepage. A hose 45 is arranged at the bottom of the connecting pipe 41 so that the seepage can flow to the outside through the hose 45, which is convenient for collecting the seepage. Support rods 42 are symmetrically arranged on both sides of the top of the annular guide ramp 43. A guide baffle 44 is arranged between the tops of the two groups of support rods 42 to block the top of the annular guide ramp 43 to prevent the seepage from flowing to the outside, so that the seepage can be centrally treated.

[0037] During the use of the device, the medical sponge 6 cannot completely absorb the secretions inside the nasal cavity or the cerebrospinal fluid produced due to rhinorrhoea symptoms, and the guide baffle 44 can block these liquids during the outflow process, and then these liquids flow to the annular guide ramp 43. After entering the annular guide ramp 43, under the guidance of the guide ramp 43, these exudates pass through the connecting tube 41 and the hose 45, and then flow to the outside of the device for collection, and then medical personnel can distinguish the composition of the exudate through detection.

[0038] After surgery, patients may experience nasal leakage, which will lead to exudation. At the same time, secretions from the nasal cavity will also leak out. General devices cannot effectively block these liquids, but this device can effectively block these leaked liquids and guide them to facilitate centralized treatment of these exudates. It can also facilitate the collection of these exudates to detect whether the patient has rhinorrhoea.

[0039] The top of the guide baffle 44 is made of a conical structure, and the outer side of the annular guide ramp 43 is made of a slope structure, which can be used for guidance. After the seepage falls, the seepage can be concentrated to facilitate the subsequent seepage to remain outside. Mounting holes are symmetrically provided on both sides of the top of the connecting ring 3, and the hose 45 is located inside the mounting hole. A connecting groove is provided at the bottom of the connecting pipe 41, and the top of the hose 45 is connected to the connecting pipe 41 through the connecting groove. The position of the hose 45 is limited to a certain extent to prevent the hose 45 from moving at will and affecting the normal use of the device.

[0040] Embodiment 3

[0041] See also Figure 1 , Figure 5 and Figure 6 , which is different from the second embodiment in that:

[0042] The connecting assembly 5 includes a slide bar 51, a top annular plate 52, a bottom annular plate 53, a spring 54, an insert block 55, an annular bin 56, a slot 57, an annular groove 58 and a through groove 59. A top annular plate 52 is provided at the bottom of the plug 8, a slide bar 51 is provided on one side of the bottom of the top annular plate 52, a spring 54 is provided on the outside of the slide bar 51, an insert block 55 is provided at the bottom of the slide bar 51, the bottom annular plate 53 is located on the inner side of the connecting tube 9, an annular bin 56 is provided inside the bottom annular plate 53, a slot 57 is provided on one side of the bottom of the annular bin 56, and the insert block 55 is fixed to a certain extent after being inserted into the slot 57 to improve the connection effect, a through groove 59 is provided at one end of the top of the bottom annular plate 53, so that the insert block 55 can be inserted into the inside of the annular bin 56 through the through groove 59, and after rotating to a certain position, the insert block 55 is prevented from being pulled out, an annular groove 58 is provided at a non-center position of the top of the bottom annular plate 53, and the annular groove 58 and the through groove 59 are connected.

[0043] When the medical sponge 6 needs to be replaced, first remove the device from the patient's nasal cavity and rotate the plug 8. During the rotation, the plug 8 drives the slide bar 51 and the plug block 55 to move, so that the plug block 55 is subjected to pressure. Then, under the action of the pressure, the plug block 55 gradually detaches from the inside of the slot 57, and at the same time drives the spring 54 to be compressed. Then, the plug 8 continues to be rotated, and a certain upward pulling force is applied to the plug 8. When the plug 8 is rotated to the specified position, the position of the slot 57 and the slide bar 51 coincides with the position of the through slot 59. Then, under the action of the upward force, the slot 57 is pulled to the outside, and the plug 8 and the connecting tube 9 are separated. At this time, the medical sponge 6 and the plug 8 are replaced.

[0044] Generally, a nasal breathing assist device after pituitary tumor surgery needs to be replaced after being used for a period of time, and the replacement method is to replace the entire device. The positions that normally need to be replaced are the positions where the medicine is stored. Replacing the entire device will increase the cost of treatment. However, after the device has been used for a period of time, the plug 8 can be disassembled separately, and then when replacing it, only part of the device needs to be replaced, thereby effectively reducing the loss of medical devices, thereby reducing the cost of treatment, and the replacement is convenient and simple, which effectively reduces the difficulty of operation.

[0045] The slot 57 and the plug block 55 are both made of a conical structure. The plug block 55 and the slot 57 are adapted to each other. After the plug block 55 is subjected to pressure, the plug block 55 can be pulled out from the inside of the slot 57 under the guidance of the inclined surface, so as to facilitate the release of the fixation of the plug 8. The spring 54 is respectively connected to the slide rod 51 and the plug block 55 to ensure that the plug block 55 can be connected to the top annular plate 52. At the same time, the spring 54 can apply a certain thrust to the plug block 55.

[0046] A slide groove is provided at the bottom of the top annular plate 52, and the slide rod 51 is located inside the slide groove, so that the slide rod 51 can move up and down along the slide groove, which is convenient for subsequently driving the plug block 55 out of the slot 57. The width of the through groove 59 is greater than the diameter of the plug block 55. The through groove 59 and the annular groove 58 are connected to the annular warehouse 56. After the plug block 55 moves to a position overlapping with the through groove 59, the plug block 55 and the position of the through groove 59 can be pulled out to the outside, thereby releasing the connection between the plug 8 and the connecting pipe 9.

[0047] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
