[0002] At present, in the diagnosis of patients with respiratory infectious diseases, it is often necessary to collect sputum samples from the patients. However, in the process of collecting sputum samples, the patients directly cough up sputum, and the patients' airway droplets, aerosols, etc. will splash and float in the air, leading to the transmission of the virus. Summary of the invention

[0003] The purpose of the present invention is to provide a splash-proof sputum collection device to solve the problem of virus infection when collecting sputum from patients with respiratory infectious diseases.

[0004] The technical solution of the present invention to solve the above technical problems is as follows:

[0006] When collecting sputum of a patient, the present invention covers the face of the patient with a mask to prevent airway droplets, aerosols and the like from splashing when the patient coughs up sputum, thereby preventing virus transmission. The sputum enters the sputum collecting cup from the diversion tube to complete the sputum collection. After the sputum collection is completed, the first sleeve is folded upward to cover the mask and is sealed with a drawstring. The second sleeve covers the bottom end opening of the diversion tube and is sealed with a drawstring to prevent airway droplets, aerosols and the like in the mask and the diversion tube from floating in the air, thereby preventing virus transmission.

[0007] Furthermore, the top ends of the first sleeve and the second sleeve are respectively sealed and connected to the outer side wall of the flow guide pipe, and the second sleeve is located inside the first sleeve.

[0008] When the first sleeve and the second sleeve of the present invention are sealed with the flow guide tube, airway droplets and aerosols can be prevented from seeping out.

[0009] Furthermore, the above-mentioned first sleeve is in the shape of a truncated cone, and the top opening size of the first sleeve is smaller than the bottom opening size of the first sleeve, the bottom opening size of the first sleeve is larger than the cross-sectional size of the mask, and the length of the first sleeve is larger than the distance between the top of the mask and the top of the first sleeve.

[0010] The first sleeve of the present invention, which is in the shape of a truncated cone (i.e., a skirt), is easy to fold upward and easily cover the mask, so that after sputum collection is completed, the mask can be quickly and effectively covered, shortening the contact time between the inside of the mask and the outside world and reducing the risk of viral infection.

[0011] Furthermore, the second sleeve is also in a truncated cone shape, and the top opening size of the second sleeve is smaller than the bottom opening size of the second sleeve, and the bottom end of the guide tube is located in the second sleeve.

[0012] The second sleeve of the present invention is in the shape of a truncated cone (i.e., a skirt), which can facilitate the connection and disconnection between the sputum collecting cup and the drainage tube, and can also quickly cover the bottom end of the drainage tube, shortening the time that the bottom end opening of the drainage tube is in contact with the outside world, thereby reducing the risk of viral infection.

[0013] Furthermore, the first sleeve and the second sleeve are transparent plastic films.

[0014] The first sleeve and the second sleeve of the present invention adopt transparent plastic film, which is convenient for observing the sputum collection situation when collecting sputum, and the plastic film has low cost, which can reduce the cost of the sputum collection device when it is used once.

[0015] Furthermore, the above-mentioned sputum collecting cup includes a cup body and a cup cover; the top inner wall of the cup body is connected to the bottom outer wall of the guide tube; the inner wall of the cup cover is connected to the bottom outer wall of the cup body.

[0016] The present invention connects the cup cover of the sputum collecting cup to the bottom of the cup body, the cup cover is easy to store, and the sealing of the cup body is convenient, thus shortening the contact time between the inside of the sputum collecting cup and the outside world and reducing the risk of virus infection.

[0017] Furthermore, the cup body is connected to the guide tube via threads, the cup cover is also connected to the cup body via threads, and the top outer wall of the cup body is provided with threads matching the inner wall of the cup cover.

[0018] Furthermore, the above-mentioned sputum collecting cup also includes a third sleeve; the third sleeve is in the shape of a truncated cone, and the top opening size of the third sleeve is smaller than the bottom opening size of the third sleeve, the top end of the third sleeve is sleeved on the outside of the cup body and sealed with the outer wall of the cup body, and the bottom end of the third sleeve is provided with a drawstring.

[0019] The third sleeve of the present invention is in the shape of a truncated cone (i.e., a skirt type), which can cover the cup cover connected to the cup mouth of the cup body after sputum collection is completed, thereby reducing the risk of virus spreading outward from the cup mouth of the cup body, thereby reducing the risk of viral infection.

[0020] Furthermore, the mask is provided with a plurality of ventilation holes, and a waterproof and breathable membrane is provided in the ventilation holes; fixing ropes are connected to both sides of the mask.

[0021] The invention is provided with a ventilating hole of the waterproof breathable membrane, which is convenient for ventilating the patient and preventing the patient from hypoxia. The fixing rope is convenient for fixing the mask to the patient's head, meeting the demand of collecting sputum specimens for a long time.

[0022] Furthermore, the mask is made of transparent plastic.

[0023] The mask of the present invention adopts transparent plastic, which is convenient for observing the sputum collection situation when collecting sputum, and the plastic film has low cost, which can reduce the cost of the sputum collection device when it is used once.

[0024] The present invention has the following beneficial effects:

[0025] (1) When collecting sputum specimens, the present invention covers the patient's face with a mask. After the collection is completed, the first sleeve is folded upward to cover the mask and is sealed with a drawstring. The second sleeve covers the bottom opening of the guide tube and is sealed with a drawstring, thereby preventing the patient's airway droplets, aerosols, etc. from floating in the air during and after the collection process, thereby preventing the virus from being transmitted.

[0026] (2) After sputum collection is completed, the anti-splash sputum collection device of the present invention can quickly cover the openings of the mask and the drainage tube, and can quickly double-seal the sputum collection cup (the cup cover and the third sleeve respectively seal the cup body), thereby shortening the contact time between the mask, the drainage tube and the sputum collection cup and the outside world, and reducing the risk of virus transmission to humans.

[0027] (3) The present invention can observe the process of sputum collection and reduce the cost of one-time use. BRIEF DESCRIPTION OF THE DRAWINGS
