Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a pediatric sputum suction device with an anti-bite function. Background Art

[0002] Suctioning refers to sucking out secretions from the respiratory tract through the oral cavity, nasal cavity, and artificial airway (tracheotomy) to keep the respiratory tract open. In the diagnosis and treatment of respiratory diseases in pediatric internal medicine, it is often necessary to use a suction device to suction the sputum of the child.

[0003] A Chinese patent discloses a sputum collection device for pediatric internal medicine (authorization announcement number CN212326452U). The collection tube of the device is provided with an oral support ring, which can be placed in the mouth of the child to prevent the child from biting or licking the collection tube. A connector is provided between the collection tube and the input head to avoid contamination of the sputum sample.

[0004] According to the above comparative cases, the above device uses an oral support ring to prevent the child from biting or licking the collection tube. Since the oral support ring is directly placed in the child's mouth and is sleeved on the surface of the collection tube, when the child is unwilling to open his mouth after suctioning, the oral support ring is blocked by the child's mouth, which will undoubtedly increase the difficulty of removing the oral support ring. In addition, placing the oral support ring completely inside the mouth also increases the probability of the child swallowing it accidentally, posing a safety hazard.

[0005] Therefore, a pediatric sputum suction device with an anti-bite function is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a pediatric sputum suction device with an anti-bite function in order to solve the above-mentioned problem, thereby improving the problem of low safety factor in the use of the existing pediatric sputum suction device with an anti-bite function.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme, which is a pediatric sputum suction device with an anti-bite function, comprising: an electric sputum suction device, the end of which is plugged into and connected to a collection tube; and an anti-bite mechanism, which is sleeved on the surface of the collection tube.

[0008] Preferably, the anti-bite mechanism includes a ring cylinder sleeved on the surface of the collection tube. The surface of the ring cylinder is fixedly connected with a first positioning ring and a second positioning ring. The first positioning ring and the second positioning ring are respectively arranged on both sides of the center point of the ring cylinder. When the child bites the ring cylinder, the ring cylinder can prevent the upper and lower rows of the child's teeth from closing, avoiding the child from biting the collection tube, so as to ensure that the electric suction apparatus can normally perform the suction operation through the collection tube. At the same time, when the child spits out the ring cylinder, the first positioning ring can resist the inner side of the child's teeth, making it impossible for the child to normally spit out the ring cylinder. When the child swallows the ring cylinder, the second positioning ring can resist the outer side of the child, making it impossible for the child to normally swallow the ring cylinder. This can not only improve the overall stability of the anti-bite mechanism in use, but also improve the safety factor of the anti-bite mechanism in use.

[0009] Preferably, the edges and corners of the first positioning ring and the second positioning ring are all rounded, which can reduce the probability of the child's oral cavity or mouth skin being scratched, and further improve the safety factor of the anti-bite mechanism in use.

[0010] Preferably, the cross-sectional height ratio of the first positioning ring to the second positioning ring is 1:2, and the first positioning ring is arranged on the side of the second positioning ring facing away from the electric suction apparatus, which can reduce the difficulty for medical staff to place the anti-bite mechanism.

[0011] Preferably, the ring cylinder, the first positioning ring and the second positioning ring are all integrally formed, and the ring cylinder, the first positioning ring and the second positioning ring are all made of medical PVC materials, which can improve the overall strength of the anti-bite mechanism, avoid the probability of the child biting and breaking the anti-bite mechanism, and further improve the safety factor of the anti-bite mechanism in use.

[0012] Preferably, the vertical cross-sectional shapes of the ring cylinder, the first positioning ring and the second positioning ring are all elliptical rings, which can reduce the probability of the ring cylinder twisting in the child's oral cavity, and further improve the stability of the anti-bite mechanism in use.

[0013] Preferably, a guide tube is fixedly connected to the inner side of the ring cylinder, the collection tube is inserted into the inner side of the guide tube, and one end of the collection tube penetrates to the outside of the guide tube, which can more stably guide the collection tube in and out of the child's respiratory tract to improve the stability of the collection tube in use.

[0014] Preferably, medical silicone sleeves are arranged on the surfaces of the ring cylinder, the first positioning ring and the second positioning ring, and the three medical silicone sleeves are integrally formed, which can reduce the hardness feeling of the child's bite on the surface of the ring cylinder to reduce the discomfort during the child's biting process.

[0015] Preferably, the surface of the middle medical silicone sleeve is provided with uniformly distributed resistance-increasing strips. The resistance-increasing strips are components made of medical silicone materials and are parallel to the axis line of the annular cylinder. This can increase the friction force between the medical silicone sleeve and the child's teeth, and further improve the stability of the anti-bite mechanism during use.

[0016] The beneficial effects of the present utility model are as follows:

[0017] When the child bites the annular cylinder, the annular cylinder can prevent the upper and lower rows of the child's teeth from closing, avoiding the child from biting the collection tube, so as to ensure that the electric suction apparatus can normally perform the suction operation through the collection tube. At the same time, when the child spits out the annular cylinder, the first positioning ring can resist the inner side of the child's teeth, making it impossible for the child to normally spit out the annular cylinder. When the child swallows the annular cylinder, the second positioning ring can resist the outer side of the child, making it impossible for the child to normally swallow the annular cylinder. This can not only improve the overall stability of the anti-bite mechanism during use, but also improve the safety factor of the anti-bite mechanism during use. Description of the Drawings
