Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a sputum collecting device for a medical tracheotomy cannula. Background Art

[0002] Tracheotomy is to cut the cervical trachea and insert an outer cannula and an inner cannula, which is a common operation to relieve laryngeal dyspnea, respiratory dysfunction or dyspnea caused by retention of lower respiratory tract secretions. During the insertion and treatment of the tracheotomy tube, the patient often coughs violently, causing sputum to splash out. Therefore, it is necessary to suction the sputum from the patient in time, and the existing sputum collecting device needs to insert a suction tube to remove the sputum.

[0003] The existing sputum collecting device first collects the sputum and then discharges it. However, when too much sputum accumulates, the airflow from the patient's cough will blow up the sputum collected at the bottom, causing the sputum to be exposed to the air through the ventilation port. And if the patient discharges sputum during the operation, when the patient suddenly coughs during the sputum discharge process, the sputum will also be directly sprayed into the air from the discharge port, polluting the surgical environment. Content of the Utility Model

[0004] The utility model aims at the above problems in the prior art and provides a sputum collecting device for a medical tracheotomy cannula, which is realized through the following technical solutions:

[0005] A sputum collecting device for a medical tracheotomy cannula includes an outer cannula and an inner cannula. The inner cannula is slidably inserted into the outer cannula. An inner support plate is fixedly sleeved on the outer side of one end of the inner cannula that is not inserted into the outer cannula. An outer support plate is fixedly sleeved on the outer side of one end of the outer cannula where the inner cannula is inserted. A collecting tube is connected to the end of the inner cannula away from the outer cannula. A connector is installed on the outer sides of the collecting tube and the inner cannula. A sputum collecting chamber is connected to the side of the collecting tube away from the inner cannula. A sputum discharging tube is communicated with the bottom of the sputum collecting chamber. A sputum storage chamber is communicated with the bottom of the sputum discharging tube. An excrement discharging tube is communicated with the bottom of the sputum storage chamber. A first valve is installed on the sputum discharging tube, and a second valve is installed on the excrement discharging tube.

[0006] The utility model is further arranged as follows: a baffle in the shape of a letter L rotated 90° clockwise is connected to the top of the collecting tube. The baffle is located in the sputum collecting chamber, and the long side of the baffle is fixedly connected to the collecting tube.

[0007] The utility model is further arranged as follows: a diversion plate is fixedly connected to the bottom of the short side of the baffle, and one end of the diversion plate away from the baffle is inclined towards the side of the collecting tube.

[0008] The utility model is further arranged as follows: the sputum collecting chamber is a hollow shell. An opening is formed at the top of the side wall of the sputum collecting chamber connected to the collecting tube, and a chamber cover is hinged at the opening.

[0009] In summary, the beneficial technical effects of the present utility model are as follows:

[0010] After the sputum is collected into the sputum collection bin, the first valve is opened under the condition that the second valve is closed, so that the sputum first enters the sputum storage bin. In this way, when expectorating, even if the patient suddenly coughs, the sputum will not be sprayed out from the sputum discharge port. Moreover, after the sputum enters the sputum storage bin and the first valve is closed, when the patient coughs again, the accumulated sputum will not leak out from the air vent, ensuring the surgical environment; after the sputum coughed up by the patient enters the sputum collection bin through the collection tube, it is first blocked by the baffle to prevent the sputum from splashing all over the sputum collection bin and leaking into the air from the opening when the patient breathes; the sputum collection bin outlet is blocked by the bin cover, but the bin cover can move back and forth when the patient breathes, without hindering the patient's breathing.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0014] Embodiment

[0015] As Figure 1 shown, a sputum collection device for a medical tracheotomy cannula disclosed by the present utility model includes an outer sleeve tube 1 and an inner sleeve tube 2. The inner sleeve tube 2 is slidably inserted into the outer sleeve tube 1. An inner support plate 3 is fixedly sleeved on the outer side of one end of the inner sleeve tube 2 that is not inserted into the outer sleeve tube 1. An outer support plate 4 is fixedly sleeved on the outer side of one end of the outer sleeve tube 1 that inserts the inner sleeve tube 2. A collection tube 5 is connected to the end of the inner sleeve tube 2 away from the outer sleeve tube 1. A connector 6 is installed on the outer sides of the collection tube 5 and the inner sleeve tube 2. The side of the collection tube 5 away from the inner sleeve tube 2 is connected to a sputum collection bin 7. The bottom of the sputum collection bin 7 communicates with a sputum discharge tube 8. The bottom of the sputum discharge tube 8 communicates with a sputum storage bin 9. The bottom of the sputum storage bin 9 communicates with a sputum outlet tube 10. A first valve 11 is installed on the sputum discharge tube 8. A second valve 12 is installed on the sputum outlet tube 10.

[0016] The top of the collection tube 5 is connected to a baffle 13 in the shape of a letter L rotated 90° clockwise. The baffle 13 is located in the sputum collection bin 7, and the long side of the baffle 13 is fixedly connected to the collection tube 5.

[0017] A flow guide plate 14 is fixedly connected to the bottom of the short side of the baffle plate 13, and one end of the flow guide plate 14 away from the baffle plate 13 is inclined towards the side of the collection pipe 5.

[0018] The sputum receiving bin 7 is a hollow shell, and an opening is provided at the top of the side wall of the sputum receiving bin 7 connected to the collection pipe 5, and a bin cover 15 is hinged at the opening.

[0019] Specific implementation mode of this example: Insert the outer sleeve 1 into the opening at the patient's neck, insert the inner sleeve 2 into the outer sleeve 1. When the patient coughs, sputum enters the sputum receiving bin 7 through the inner sleeve 2 and the collection pipe 5. Under the action of the baffle plate 13, the sputum flows to the bottom of the sputum receiving bin 7. Open the first valve 11 under the condition of closing the second valve 12 to let the sputum flow into the sputum storage bin 9, and then close the first valve 11. When there is too much sputum in the sputum storage bin 9, open the second valve 12 to discharge the sputum under the condition of closing the first valve 11.
