Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field, concretely is a kind of nasal plug fixing device for oxygen inhalation in cardiovascular internal medicine. BACKGROUND

[0002] Cardiology, i.e. cardiovascular internal medicine, is a clinical department set in internal medicine of hospitals at all levels for diagnosis and treatment of cardiovascular diseases. Patients in cardiovascular internal medicine often need oxygen inhalation to correct hypoxia, and need to use nasal plugs and nasal catheters during oxygen inhalation.

[0003] The existing nasal catheter is usually directly connected to the outside of the oxygen inhalation tube, and is sleeved on the head by a head ring, and then the nasal plug and the nasal catheter are inserted into the nostril for oxygen inhalation. Because the shape of the two nasal catheters is fixed, it is bent and folded in the middle under the bending action of the oxygen tube. When the head is moved, it will touch the head ring, and under the pulling of the head ring, the nasal catheter is easily detached from the inside of the nostril. The stability of the nasal catheter during fixation is poor, and it is easy to tilt and fall off. When the patient cannot insert the nasal catheter into the nostril again, it is easy to cause the patient to be hypoxic, and there is a certain safety hazard. SUMMARY

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] Please refer to Figures 1-5 In the embodiments of the utility model, a nasal plug fixing device for oxygen inhalation in a cardiovascular medicine department comprises a connecting assembly 1, the connecting assembly 1 comprises a mounting plate 101, the mounting plate 101 is symmetrically provided with a connecting plate 104 movably on the upper surface, a fixed assembly 2 is installed on the upper surfaces of the two connecting plates 104, the fixed assembly 2 comprises a plurality of support rods 201 symmetrically arranged on the upper surfaces of the two connecting plates 104, the plurality of support rods 201 are provided with two mounting rings 202, a plurality of arc-shaped sheets 203 are fixedly installed at equal angles on the upper surfaces of the mounting rings 202, and a plurality of conical sheets 205 are arranged at equal angles outside the arc-shaped sheets 203.

[0027] Specifically, the connecting assembly 1 is used for connecting the oxygen tube 3 and the nasal catheter 301 and limiting the positions of the two, and the fixed assembly 2 is supported inside the nostril to fix the nasal catheter 301.

[0028] Embodiment one

[0029] For example Figure 1 Figure 2 and Figure 5As shown, in this embodiment, the oxygen tube 3 is disposed between two symmetrical support rods 201, and the two nasal cannulas 301 on the outside of the oxygen tube 3 are movably inserted into the two fixed components 2; a plurality of spherical locking blocks 105 are symmetrically fixedly installed on the upper surface of the mounting plate 101, and a plurality of slots 106 are equidistantly opened on one side surface of the connecting plate 104, and the spherical locking blocks 105 are movably engaged with the slots 106 at the corresponding positions.

[0030] In this embodiment, the spherical locking block 105 and the locking slot 106 can be engaged to allow for quick disassembly and assembly of the connecting plate 104 and the mounting plate 101, facilitating the disassembly of the oxygen tube 3 and the nasal cannula 301, and enabling the device to be reused after disinfection.

[0031] like Figures 2-4 As shown, in this embodiment, a threaded sleeve 206 is movably sleeved on the outer side of the arc-shaped piece 203, and threads are opened on the outer surface of multiple arc-shaped pieces 203. The threaded sleeve 206 is screwed into the threads, and a tapered guide surface 207 is provided on the outer surface of the threaded sleeve 206. Fixing rods 204 are fixedly installed on the upper surface of multiple arc-shaped pieces 203, and connecting ropes 208 are fixedly connected to the upper end of multiple fixing rods 204. Connecting holes 209 are opened at the upper end of both sides of the tapered piece 205, and the connecting ropes 208 pass through the connecting holes 209 and are fixedly connected to the connecting holes 209.

[0032] In practice, the threaded sleeve 206 is rotated, and through its engagement with the thread, the threaded sleeve 206 rotates upward. The conical guide surface 207 on its outer side opens the conical plate 205 from the lower inner side, causing multiple conical plates 205 to unfold outward. The unfolding angle of the conical plate 205 is adjusted according to the size of the nostril, and it and the nasal cannula 301 are inserted into the nostril. At this time, the outer edge of the unfolded part of the conical plate 205 supports the nostril, fixing the nasal cannula 301. Thus, the unfolding angle is adjusted according to the size of the patient's nostril, so that multiple conical plates 205 support the inner wall of the nostril, fixing the nasal cannula 301 and improving its firmness.

[0033] like Figure 1 As shown, in this embodiment, two first tether ropes 102 of different lengths are provided at one end of both sides of the mounting plate 101, and two second tether ropes 103 of different lengths are provided at the other end of both sides of the mounting plate 101.

[0034] In practice, the longer first tether 102 is wrapped around the lower part of the patient's head and tied together with the shorter first tether 102 at the side of the face. The longer second tether 103 is wrapped around the upper part of the patient's head and tied together with the shorter second tether 103 at the side of the face. In this way, the mounting plate 101 is double-fixed by the two tethers above and below the patient's head to prevent the nasal cannula 301 from falling out of the nostril when the head is moved, thereby reducing the safety hazards caused by the patient's hypoxia.

[0035] It will be obvious to a person skilled in the art that the application is not limited to the details of the above-described exemplary embodiments, but that the application can be implemented in other concrete forms without departing from the spirit or essential characteristics of the application. The embodiments should, therefore, be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the above description, and all changes which come within the meaning and range of equivalents of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the scope of the claims concerned.

[0036] Furthermore, it should be understood that although the present specification describes exemplary embodiments, the application is not limited to only one independent technical solution in each embodiment, and the specification is described in this way only for the sake of clarity. A person skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that a person skilled in the art can understand.
