Description

Technical Field

[0001] The utility model relates to the field of children's medical devices, in particular to a fixing device for nasal negative pressure replacement therapy. Background Art

[0002] Nasal negative pressure replacement therapy refers to a method of using a suction device to create negative pressure in the sinuses, suck out sinus secretions and allow medicinal liquid to enter the sinuses to achieve the treatment purpose. It is commonly used in the treatment of sinusitis, especially in the treatment of chronic sinusitis in children. During nasal negative pressure replacement therapy, the patient needs to maintain a supine head-down position, that is, pad the shoulders and extend the neck so that the line connecting the chin and the external auditory meatus is perpendicular to the ground.

[0003] There are certain difficulties in the clinical operation of nasal negative pressure replacement therapy. The main reason is that usually patients, especially child patients, are very resistant to such a position. One is because of fear, and the other is because lying in bed with the head supine will feel uncomfortable. The child's neck is in a suspended state and the head is difficult to fix, resulting in the problem that it is easy to damage the nasal mucosa of the child during operation and cause additional harm. To improve this situation, fixing devices for nasal negative pressure replacement therapy have emerged on the market. For example, the patent with the application number 202020683255.3 discloses a fixing device for nasal negative pressure replacement therapy, including a base, a first fixing band and a second fixing band. The middle part of the first fixing band straddles the base and is above the position matching the child's head, and the second fixing band is installed on both sides of the base. The middle part of the first fixing band straddles the base and is above the position matching the child's upper body to solve the problem of inconvenient fixation of child patients in nasal negative pressure replacement therapy. However, when the device is used, it is necessary to tightly fix the child, which will lead to greater resistance and psychological pressure of the child and cause doctor-patient contradictions. Content of the Utility Model

[0004] The utility model aims to provide a fixing device for nasal negative pressure replacement therapy, to provide a comfortable auxiliary environment for the patient to maintain the correct posture during treatment and reduce the treatment pressure of the patient.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A fixing device for nasal negative pressure replacement therapy, including a shoulder pad and a cloth cover. The cloth cover is detachably sleeved on the shoulder pad; the bottom surface of the shoulder pad is a plane, and the top surface of the shoulder pad is integrally an arc surface, and the top surface includes a first arc section, a horizontal section and a second arc section connected in sequence. A limiting groove is obliquely arranged in the first arc section. The limiting groove is an arc groove, and blocking parts are arranged on both sides of the limiting groove.

[0006] The beneficial effects of this solution are as follows: 1. By setting a limit groove on the shoulder pad to limit the neck of the patient, the limit groove is an arc groove. When assisting the child to maintain a standard supine head-down position, the neck of the child is fully supported in an arc wrapping manner, improving comfort while ensuring the support strength and limit effect, and achieving the purpose of reducing the treatment pressure of the patient.

[0007] 2. The cloth cover can be detachably sleeved on the shoulder pad. By disassembling and replacing the cloth cover for cleaning and disinfection, the device can be recycled, reducing the use cost; moreover, if the cloth cover is set in different colors and patterns for different child patients, it helps to distract the child's attention and achieve the purpose of relieving the child's emotions.

[0008] 3. The blocking parts on both sides of the limit groove increase the structural strength of the limit at both ends of the neck, thereby further strengthening the limiting effect.

[0009] 4. By setting the top surface to include a first arc segment, a horizontal segment, and a second arc segment connected in sequence, the foreign body sensation of using the shoulder pad can be reduced, and the comfort of using this device can be further improved.

[0010] Preferably, the length of the first arc segment in the horizontal direction is less than the length of the second arc segment in the horizontal direction.

[0018] The following is a further detailed description through specific embodiments:

[0019] The reference numerals in the accompanying drawings of the description include: shoulder pad 1, limiting groove 11, blocking portion 12, first arc segment 13, horizontal segment 14, second arc segment 15, and dust-proof pad 2.

[0020] Embodiment

[0021] The embodiment is basically as shown in the attached Figures 1-3 shown. As Figure 1 shown, a fixing device for nasal negative pressure replacement therapy includes a shoulder pad 1 and a cloth cover (both the cloth cover and the figure are not shown). The cloth cover is detachably sleeved on the shoulder pad 1. By disassembling and replacing the cloth cover for cleaning and disinfection, the recycling use of this device can be realized, and the use cost can be reduced. The cloth cover is set in different colors and different patterns for use by different child patients, which helps to transfer the attention of the children and achieve the purpose of relieving the emotions of the children.

[0022] The shoulder pad 1 is placed under the child to assist in maintaining the supine head-down position. Combining Figure 1 and Figure 2 shown, the shoulder pad 1 is generally square as a whole. The bottom surface of the shoulder pad 1 is a plane to improve the stability of the shoulder pad 1 after being placed; the top surface of the shoulder pad 1 is generally an arc surface. The top surface includes a first arc segment 13, a horizontal segment 14, and a second arc segment 15 connected in sequence from left to right. A limiting groove 11 is opened in the middle of the first arc segment 13. The limiting groove 11 is used to support and limit the neck of the child. The limiting groove 11 is obliquely opened downward from the top surface of the first arc segment 13. After being opened, the limiting groove 11 is an arc groove, the width of the middle part thereof is the largest, and both ends are arc-shaped and smoothly closed, and a blocking portion 12 is formed at both ends of the first arc segment 13. The arc-shaped limiting groove 11 conforms to ergonomics more, and provides all-round support for the neck of the child in an arc wrapping manner, improving comfort while ensuring the support strength and limiting effect; the blocking portions 12 on both sides of the limiting groove 11 increase the structural strength of the limiting structure at both ends of the neck, so as to further strengthen the limiting effect.

[0023] The material of the shoulder pad 1 is sponge with a certain hardness. In this embodiment, it is polyurethane sponge, so that the shoulder pad 1 can provide sufficient support strength and has the characteristic of good softness. As Figure 2As shown in the figure, the length of the first arc segment 13 in the horizontal direction is less than that of the second arc segment 15 in the horizontal direction, that is, the overall slope of the second arc segment 15 is smoother. When in use, the shoulders of the child patient are located on the horizontal segment 14, the neck of the child is embedded in the first arc segment 13, and the back of the child is located on the second arc segment 15. In the supine state, the second arc segment 15 with a smoother slope not only reduces the foreign body sensation of using the shoulder pad 1, but also can concentrate the extrusion force exerted by the child on the shoulder pad 1 towards the horizontal segment 14 while reducing the back support force, thereby enhancing the stability of the horizontal segment 14 after placement through the gravity of the patient itself and improving the fixation effect on the neck. The length of the horizontal segment 14 can further provide a bearing area for the weight of the child acting on the shoulder pad 1.

[0024] For the usage requirements of child patients, the length of the shoulder pad 1 is set to be 40 - 60 cm, the width is 30 - 50 cm, the height of the parallel segment is 5 - 15 cm, the arc length of the inner wall of the limiting groove 11 is 15 - 25 cm, and the width of the limiting groove 11 is 5 - 10 cm. While achieving the overall support for the child, the volume of the device is controlled, enabling the device to be applied to different treatment conditions. In this embodiment, the length of the shoulder pad 1 is set to 50 cm, the width is 40 cm, the height of the parallel segment is 10 cm, the arc length of the inner wall of the limiting groove 11 is 20 cm, and the width of the limiting groove 11 is 5 cm.

[0025] As Figure 2 shown, it further includes a dust-proof pad 2. One end of the dust-proof pad 2 is fixed to the bottom of the shoulder pad 1, and combined Figure 1 shown, the width of the dust-proof pad 2 is greater than the width of the shoulder pad 1, that is, the dust-proof pad 2 can cover the shoulder pad 1 to ensure the dust-proof effect, thereby achieving the shielding and dust-proofing of the device during storage and facilitating its use at any time next time. In this embodiment, the dust-proof pad 2 is sewn and fixed on the cloth cover for easy disassembly and cleaning. When in use, pulling out the dust-proof pad 2 and padding it under the head of the child can also prevent the situation of polluting the hospital bed or operating table due to improper operation; the dust-proof shielding surface of the dust-proof pad 2 is not the same surface as the surface that will contact the head of the child, that is, during storage, even if the dust-proof shielding surface of the dust-proof pad 2 is polluted, it does not affect normal use. And, the connection part of the dust-proof pad 2 is located on the side of the first arc segment 13 away from the horizontal segment 14. As Figure 3 shown, during treatment, by stacking the dust-proof pad 2, the height of the first arc segment 13 can be raised, thereby adapting to the use of patients with different neck lengths, adjusting according to individual differences, and enabling the child to maintain a more comfortable and standard supine head-down position for treatment.

[0026] This device is mainly aimed at the nasal negative pressure replacement treatment for child patients. The solution is different from the existing devices that need to tie up the patients during the treatment. By opening an inclined downward limiting groove 11 on the shoulder pad 1 to limit the neck of the supine child, it helps to keep the standard posture during the treatment, which is conducive to reducing the psychological pressure of the child during the treatment and alleviating their resistance. During the treatment, the cooperation of the first arc segment 13, the parallel segment and the second arc segment 15 can improve the comfort of the child, thus further improving the compliance of the child. Using sponge makes the device softer and more comfortable, and it is also easier for parents to accept. Moreover, when this device is placed under the shoulders of a lying patient, it ensures that the patient can maintain the best supine head-down position for nasal negative pressure replacement operation, which is beneficial to the treatment operation of medical staff and also alleviates the treatment pressure of medical staff.
