Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a splash prevention device for tracheotomy patients. Background Art

[0002] Tracheotomy is a surgical procedure that cuts open the anterior wall of the trachea in the neck, allowing breathing to proceed through the newly created channel connected to the outside world. It is mainly used to rescue patients with laryngeal obstruction. When a patient has difficulty breathing due to a tumor or foreign body blocking the pharynx or larynx, or respiratory dysfunction causing secretions to block the lower respiratory tract, the patient suffers from hypoxia and a large amount of carbon dioxide in the blood, leading to the risk of suffocation and death. At this time, simply giving the patient oxygen cannot relieve the patient's hypoxia state, but instead further suppresses breathing. Therefore, a tracheotomy is necessary to relieve the patient's airway obstruction and alleviate breathing difficulties, thereby achieving the purpose of auxiliary treatment.

[0003] However, during the incision process, exposure to aerosols and secretions from patients with respiratory diseases is a high-risk factor for infection for medical staff. Studies have shown that procedures such as endotracheal intubation, suctioning, and nebulizer treatment generate large amounts of aerosols and droplets. Compared with non-exposed personnel, medical staff exposed to these high-risk procedures have a 2.86-fold increased infection rate. During the care of tracheotomy patients, it is necessary to control the splashing of patients' aerosols or secretions to avoid cross infection. Summary of the Invention

[0033] The puncture needle 6 is arranged on the upper part of the bottom plate sealing layer 17, and the bottom plate sealing layer 17 is made of silicone material.

[0034] The extended sliding member 3 includes a wrapping inner ring 10, a connecting outer ring 11, a sliding ring 12 and a snap fit 13. The wrapping inner ring 10 is wrapped around the outside of the negative pressure capsule cavity 4, the connecting outer ring 11 is arranged on the upper part of the wrapping inner ring 10, the sliding ring 12 and the outer circular ring 23 are arranged concentrically, the snap fit 13 is inserted into the upper part of the sliding ring 12, and the outer wall of the connecting outer ring 11 is fixedly connected to the inner wall of the sliding ring 12.

[0035] A spiral protrusion 26 is provided on the inner wall of the wrapped inner ring 10, and a hand-held fixing ring 27 is fixedly provided on the bottom of the wrapped inner ring 10. An outer ring hole 28 is provided on the upper part connected to the outer ring 11, and the clamping part 13 is inserted into the outer ring hole 28. A clamping bottom ring 29 is fixed on the top of the sliding ring 12, and the clamping bottom ring 29 is provided with a bottom ring hole 31.

The clamping part 13 includes a sliding block 32 and a support spring 33. The sliding block 32 is connected to the support spring 33, and the sliding block 32 is arranged in the bottom ring hole 31.

[0036] The sidewalls of the convex bottom plate 16 are inclined, and the side surfaces of the sliding block 32 are inclined, and the side surfaces of the sliding block 32 are in contact with the sidewalls of the convex bottom plate 16 .

[0037] When in use, the connecting short tube 8 in the device of the present invention is connected to the three-way tube connected to the endotracheal tube. When the endotracheal tube needs to be replaced or removed, the residual secretions of the patient are sucked out to prevent the secretions from splashing due to external stimulation when the endotracheal tube is removed. The medical staff pinches the outer wall of the hand-gripping fixed ring 27 wrapped around the inner ring 10 with one hand, and twists the rotating ring 21 with the other hand, and drives the negative pressure ring cavity 14 to generate negative pressure through the fixed ring 20 fixed to the rotating ring 21. As the spiral groove 18 on the outer wall of the negative pressure ring cavity 14 engages with the spiral protrusion 26 on the inner wall of the wrapped inner ring 10, the negative pressure ring cavity 14 moves inward in the wrapped inner ring 10 while the negative pressure ring cavity 14 rotates. The convex bottom plate 16 at the upper end of the negative pressure ring cavity 14 moves synchronously with the negative pressure ring cavity 14. The convex bottom plate 16 moves to the sliding block 32 of the engaging member 13. The convex bottom plate 16 pushes the sliding block 32 in the upward process. The sliding block 32 moves sideways. During the process, the support spring 33 at the rear is squeezed, and the negative pressure ring cavity 14 continues to move upward until the annular groove 15 reaches the sliding block 32. Under the reset action of the support spring 33, the sliding block 32 is reset to the sliding groove of the sliding block 32, fixing the negative pressure capsule cavity 4 and connecting the outer ring 11, and the bottom plate sealing layer 17 at the bottom plate hole 19 of the convex bottom plate 16 is penetrated by the puncture needle 6. The puncture needle 6 connects the negative pressure ring cavity 14 and the connecting short tube 8. As the negative pressure in the connecting short tube 8 increases, the negative pressure in the connecting short tube 8 increases. The annular cavity 14 forms a negative pressure state to suck secretions, and the secretions enter the negative pressure annular cavity 14 through the one-way valve plate 9 in the connecting short tube 8. When a large amount of secretions flows in instantly and fills the negative pressure annular cavity 14, the sliding ring 12 slides downward, squeezing the compression spring 30, and the distance between the sliding ring 12 and the outer ring 23 is increased to receive the secretions. When the suction is stopped, if the analysis shows that there are still secretions, a new device is replaced until the secretions are no longer sucked out.

[0038] The above is the overall workflow of the present invention. Just repeat this step next time you use it.

[0039] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
