Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a nasal cavity support device and a nasal cavity support apparatus. Background Art

[0002] Nasal cavity diseases (such as nasal septum deviation, nasal polyps, sinusitis, nasal cavity stenosis, nasal cavity atresia, etc.) are relatively common in clinical practice, and surgical treatment is one of the important means. However, problems such as nasal mucosa edema, secretion accumulation, possible mucosal adhesion and restenosis in the nasal cavity after surgery can affect the recovery of nasal ventilation function and even lead to poor surgical results. Currently, the nasal cavity support tubes used clinically cannot effectively fit the anatomical structure of the nasal cavity, are prone to displacement, and affect the support effect. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides a nasal cavity support device and a nasal cavity support apparatus, which can effectively fit the nasal cavity, are not easily displaced, and have a good support effect.

[0004] In order to solve the above problems, the present invention is implemented by adopting the following technical solutions:

[0005] A nasal cavity support device of the present invention includes a support tube, an elastic contact sleeve is sleeved outside the support tube, a plurality of support blocks are arranged on the outer wall of the support tube at equal intervals in the circumferential direction, the support blocks are located between the support tube and the elastic contact sleeve, a guide block is arranged inside the support block, a guide hole is arranged on the support tube corresponding to the guide block, the guide block extends into the corresponding guide hole and can move inwards / outwards along the corresponding guide hole, a driving mechanism is arranged at the rear end of the support tube, and the driving mechanism is used to drive all the guide blocks to move inwards / outwards synchronously along the radial direction of the support tube in the corresponding guide holes.

[0006] In this solution, the support tube is used for ventilation, which is convenient for the patient to breathe when wearing the nasal cavity support device. The front end of the support tube is pushed into the nasal cavity, so that the support tube drives the elastic contact sleeve to extend into the nasal cavity together. When the support tube and the elastic contact sleeve move to a preset position, the driving mechanism drives all the guide blocks to move outwards synchronously along the radial direction of the support tube in the corresponding guide holes, so that the guide blocks drive the support blocks to support the elastic contact sleeve in all directions. After being supported, the elastic contact sleeve abuts against the patient's nasal cavity, fixes itself and the support tube, and avoids the problem of nasal cavity blockage caused by mucosal adhesion in the nasal cavity. When it is necessary to extract the secretions in the patient's nasal cavity, the suction tube on the negative pressure suction device is extended into the support tube, and the secretions are sucked through the suction tube to prevent the accumulation of secretions and maintain the ventilation function of the nasal cavity.

[0007] Preferably, a nostril baffle is sleeved on the outer edge of the bottom of the support tube.

[0008] Preferably, a medical adhesive strip is arranged on the front end face of the nostril baffle.

[0009] In order to ensure that the nasal supporter can be firmly fixed to the nasal cavity, a medical adhesive strip is provided on the front end surface of the nostril shield. Before supporting the patient's nasal cavity, the release paper on the medical adhesive strip is torn off, and then the front end of the nasal supporter is inserted into the nasal cavity. When the nostril shield is against the nostril, the medical adhesive strip can firmly stick the two together.

[0010] Preferably, the elastic contact sleeve is cylindrical and is coaxially arranged with the support tube, and the front and rear ends of the elastic contact sleeve are respectively connected to the front and rear ends of the support tube through arc transition surfaces.

[0011] The arc transition surfaces at the front and rear ends of the elastic contact sleeve can reduce the stimulation and damage to the nasal cavity when inserting / pulling out of the patient's nasal cavity.

[0012] Preferably, a supporting arc surface is provided on the outer side of the supporting block, and the arc center of the supporting arc surface is located on the axis of the supporting tube.

[0013] The supporting arc surface on the outer side of the supporting block can better fit the inner wall of the nasal cavity and provide more uniform supporting force for the elastic contact sleeve.

[0014] Preferably, the driving mechanism includes a first tube body and a second tube body, the first tube body is arranged at the front end of the second tube body, the first tube body and the second tube body are coaxially arranged, the first tube body is in the shape of a hollow truncated cone, the outer diameter of the first tube body gradually increases from front to back, a transmission bevel is provided on the inner side of the guide block, the transmission bevel is inclined outward from front to back, the outer wall of the first tube body is in contact with the transmission bevel, the rear end of the inner wall of the support tube is provided with an internal thread, and the second tube body is provided with a first external thread matching the internal thread.

[0015] The second tube body is rotated to drive the first tube body to move forward. During the forward movement of the first tube body, since the outer wall of the first tube body abuts against the transmission inclined surface on the inner side of the guide block, as the first tube body moves forward, the four guide blocks will move outward synchronously along the corresponding guide holes, gradually propping up the elastic contact sleeve outward, causing the elastic contact sleeve to gradually abut against the patient's nasal cavity, propping up the nasal cavity to prevent blockage, and also fixing the nasal supporter in the nasal cavity.

[0016] Preferably, the second inclined surface is symmetrically provided with a yielding surface on both sides.

[0017] The yield surface can reduce the space of the guide block in the support tube. When all the guide blocks move synchronously inward along the corresponding guide holes to the limit position, all the guide blocks do not contact each other, and the space between the guide blocks is used for ventilation.

[0018] Preferably, a ring-shaped lower limit block is coaxially arranged at the bottom of the second tube body.

[0019] The lower limit block can limit the downward movement of the second tube body, preventing the second tube body from being overly screwed into the support tube, and facilitating the user to rotate the second tube body by holding the lower limit block.

[0020] Preferably, the outer side of the lower limit block is provided with a second external thread.

[0021] The second external thread on the outer side of the lower limit block can engage with the thread at the front end opening of the suction tube on the negative pressure suction device, enabling the suction of secretions without the need to insert the front end of the suction tube into the support tube, which is convenient for operation.

[0022] Preferably, there are four support blocks. When all the guide blocks synchronously move inward to the limit position along the corresponding guide holes, the four support blocks are connected end to end in sequence to form a tubular shape.

[0023] A nasal cavity support device of the present invention includes a first connecting strip, a second connecting strip, an elastic connecting rope, and two of the above-mentioned nasal cavity supports. The two ends of the elastic connecting rope are respectively fixedly connected to the outer sides of the rear end faces of the two nostril flaps. One end of the first connecting strip is fixedly connected to the inner side of the rear end face of one nostril flap, and the other end of the first connecting strip is provided with a connecting hole. One end of the second connecting strip is fixedly connected to the inner side of the rear end face of the other nostril flap, and the other end of the second connecting strip can extend into / extend out of the connecting hole.

[0024] The two nasal cavity supports are respectively connected by the first connecting strip and the second connecting strip. By pulling one of the nasal cavity supports according to the distance between the two nostrils of the patient to make it closer to / farther from the other nasal cavity support, during the movement of this nasal cavity support, the second connecting strip is driven to slide in the connecting hole. When the distance between the two nasal cavity supports is adjusted to an appropriate position, the nasal cavity support is pushed into the patient's nostril. The elastic connecting rope can be put on the patient's head to prevent the nasal cavity support from falling out of the nasal cavity.

[0025] The beneficial effects of the present invention are as follows: The driving mechanism can drive all the guide blocks to synchronously move outward along the radial direction of the support tube in the corresponding guide holes, so that the elastic contact sleeve is propped up, and the propped-up elastic contact sleeve abuts against the nasal cavity to fix the nasal cavity support; the user can connect the suction tube on the negative pressure suction device to the lower limit block, thereby extracting the secretions in the nasal cavity through the first tube body, the second tube body, and the front end of the support tube, preventing nasal cavity blockage.

[0033] Next, through embodiments and in combination with the drawings, the technical solutions of the present invention will be further specifically described.

[0034] Embodiment: A nasal cavity supporter in this embodiment, as Figures 1 to 5 shown, includes a support tube 1. An elastic contact sleeve 2 is sleeved outside the support tube 1. Four support blocks 3 are equidistantly arranged along the circumferential direction on the outer wall of the support tube 1. The support blocks 3 are located between the support tube 1 and the elastic contact sleeve 2. A guide block 4 is arranged inside the support block 3. The support tube 1 is provided with a guide hole 11 corresponding to the position of the guide block 4. The guide block 4 extends into the corresponding guide hole 11 and can move inward / outward along the corresponding guide hole 11. A driving mechanism is arranged at the rear end of the support tube 1.

[0035] A nostril baffle 5 is sleeved on the outer edge of the bottom of the support tube 1. A medical adhesive strip is arranged on the front end face of the nostril baffle 5.

[0036] The elastic contact sleeve 2 is in a cylindrical shape and is coaxially arranged with the support tube 1. The front and rear ends of the elastic contact sleeve 2 are respectively connected to the front and rear ends of the support tube 1 through arc transition surfaces 21.

[0037] The outer side of the support block 3 is provided with a support arc surface 31. The center of the arc of the support arc surface 31 is located on the axis of the support tube 1.

[0038] The driving mechanism includes a first tube body 6 and a second tube body 61. The first tube body 6 is arranged at the front end of the second tube body 61. The first tube body 6 and the second tube body 61 are coaxially arranged. The first tube body 6 is in a hollow frustum shape, and the outer diameter of the first tube body 6 gradually increases from front to back. There is a transmission inclined surface 41 inside the guiding block 4, and the transmission inclined surface 41 inclines outward from front to back. The outer wall of the first tube body 6 fits with the transmission inclined surface 41. There is an internal thread at the rear end of the inner wall of the support tube 1, and the second tube body 61 is provided with a first external thread that mates with the internal thread.

[0039] Letting surfaces 42 are symmetrically arranged on both the left and right sides of the transmission inclined surface 41.

[0040] An annular lower limit block 62 is coaxially arranged at the bottom of the second tube body 61. A second external thread is provided on the outer side of the lower limit block 62.

[0041] The surface of the elastic contact sleeve 2 is coated with an antibacterial coating, and the elastic contact sleeve 2 is made of medical silicone or polyurethane.

[0042] The antibacterial coating on the surface of the elastic contact sleeve can effectively inhibit the attachment and reproduction of bacteria on the surface of the elastic contact sleeve, reducing the risk of postoperative infection. The elastic contact sleeve is made of medical silicone or polyurethane, has good biocompatibility, softness and elasticity, can reduce the irritation to the nasal mucosa, and at the same time ensure the support strength and durability.

[0043] When it is necessary to support the patient's nasal cavity, the front end of the nasal cavity support device is pushed into the nasal cavity so that the nostril flap abuts against the nostril. Then the user rotates the lower limit block at the rear end of the second tube body, and drives the second tube body and the first tube body to move forward by rotation. During the forward movement of the first tube body, since the outer wall of the first tube body abuts against the transmission inclined surface inside the guiding block, as the first tube body moves forward, the four guiding blocks will move outward synchronously along the corresponding guiding holes, gradually pushing up the elastic contact sleeve, making the elastic contact sleeve gradually abut against the patient's nasal cavity, propping up the nasal cavity to prevent blockage, and at the same time fixing the nasal cavity support device in the nasal cavity. The support tube is used for ventilation, facilitating the patient to breathe when wearing the nasal cavity support device. During the forward movement of the second tube body, the lower limit block can limit the second tube body downward to prevent the second tube body from being screwed into the support tube excessively.

[0044] In order to ensure that the nasal cavity support device can be firmly fixed to the nasal cavity, a medical adhesive strip is provided on the front end face of the nostril flap. Before supporting the patient's nasal cavity, the release paper on the medical adhesive strip is torn off, and then the front end of the nasal cavity support device is inserted into the nasal cavity. When the nostril flap abuts against the nostril, the medical adhesive strip can firmly paste the two together.

[0045] After the nasal cavity support device is fixed to the nasal cavity, the suction tube on the negative pressure suction device is threadedly connected to the lower limit block, so as to suck and extract the secretions in the nasal cavity through the first tube body, the second tube body and the front end of the support tube, prevent nasal cavity blockage and secretion accumulation, maintain the ventilation function of the nasal cavity, and also facilitate operation.

[0046] The void can reduce the space of the guide block in the support tube. When all the guide blocks move synchronously inward along the corresponding guide holes to the limit position, all the guide blocks do not contact each other, and the space between the guide blocks is used for ventilation.

[0047] When the nasal cavity support device needs to be pulled out, rotate the lower limit block in the reverse direction to drive the second tube body and the first tube body to rotate synchronously. At this time, the second tube body drives the first tube body to move backward through the external thread. When the second tube body moves backward to the limit position, all the guide blocks lose the support of the first tube body, and all the support blocks enclose a tube shape, which is convenient for the nasal cavity support device to be pulled out of the nasal cavity.

[0048] The arc transition surfaces at the front and rear ends of the elastic contact sleeve can reduce the irritation and damage to the nasal cavity when inserting / removing the nasal cavity support device from the patient's nasal cavity.

[0049] The support arc surface on the outside of the support block can better fit the inner wall of the nasal cavity and provide a more uniform supporting force for the elastic contact sleeve.

[0050] A nasal cavity support device of this embodiment, as Figure 6 shown, includes a first connecting strip 7, a second connecting strip 71, an elastic connecting rope 72 and two of the above-mentioned nasal cavity support devices. The two ends of the elastic connecting rope 72 are respectively fixedly connected to the outer sides of the rear end faces of the two nostril flaps 5. One end of the first connecting strip 7 is fixedly connected to the inner side of the rear end face of one of the nostril flaps 5. A connecting hole is provided at the other end of the first connecting strip 7. One end of the second connecting strip 71 is fixedly connected to the inner side of the rear end face of the other nostril flap 5, and the other end of the second connecting strip 72 can extend into / extend out of the connecting hole.

[0051] In this solution, the two nasal cavity support devices are respectively connected by the first connecting strip and the second connecting strip. According to the distance between the two nostrils of the patient, pull one of the nasal cavity support devices to make it closer to / farther from the other nasal cavity support device. During the movement of this nasal cavity support device, drive the second connecting strip to slide in the connecting hole. When the distance between the two nasal cavity support devices is adjusted to a suitable position, push the nasal cavity support device into the patient's nostril, and the elastic connecting rope can be sleeved on the patient's head to prevent the nasal cavity support device from falling out of the nasal cavity.
