Description

suction device

technical field

The invention relates to a clinical medical device, in particular to a sputum suction device which integrates sputum suction and oxygen injection and has high safety.

Background technique

Clinically, many patients cannot cough up sputum on their own, and need manual assisted sputum suction to keep the airway unobstructed and facilitate lung ventilation. Therefore sucking sputum with a sputum suction device is a kind of medical device commonly used in clinical medicine.

In the prior art, the sputum suction and oxygen inhalation catheters are single-lumen. When the patient needs sputum suction and oxygen inhalation, two catheters are inserted. Repeated insertion of the catheter will directly cause damage to the tracheal mucosa, including congestion and edema, epithelial exfoliation, cilia Loss and granuloma formation, and increase the chance of bleeding and infection in patients, and often cause hypoxemia in patients due to irritating cough or insufficient oxygen supply. And when in use, the medical staff judges where to insert according to experience, and the safety is low.

However, in the prior art, if the suction tube is inserted too shallowly, the sputum in the upper part of the airway can only be sucked out completely, and all the sputum cannot be completely sucked out. The sputum in the deep part of the trachea is likely to form a sputum scab to block the airway or cause complications of pulmonary infection. . Sputum suction can also be performed under the guidance of laryngoscope or bronchofiberscope, but the former can only observe part of the airway, which is not helpful for deep suction, while the latter needs to be performed on the basis of local anesthesia, which is cumbersome to operate. The required cost is expensive, and the technical level of medical personnel is required to be high.

To sum up, the sputum suction device in the prior art has a single function, which increases the pain and cost of the patient during use, requires relatively high operational skills for the operator, and has low safety.

Contents of the invention

The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art, and provide a sputum suction device that integrates sputum suction and oxygen injection, reduces pain of patients, and is convenient to use and improves safety.

The present invention is achieved through the following technical solutions. A sputum suction device includes a tube body and a sputum suction channel arranged on the tube body, wherein: the tube body is provided with an observation cavity and an oxygen injection channel; the observation cavity The port at the sputum suction end of the tube body is transparently closed, and a miniature camera or optical fiber is arranged in the observation cavity, and the other end of the miniature camera or optical fiber is connected with the signal output end of the visual device.

The advantages of the present invention due to the adoption of the above-mentioned structure are: due to the visibility, the blindness in the sputum suction operation process is greatly reduced, the location of the sputum can be quickly and accurately found, and the sputum can be removed in time, which greatly improves the The pain of the patient is reduced, the operation of oxygen supply can be performed while sucking sputum, and the operation is simple and does not increase other operation requirements on the basis of the existing sputum suction technology.

Description of drawings

The invention can be further illustrated by the non-limiting examples given in the accompanying drawings.

Fig. 1 is a structural schematic diagram of the present invention.

Fig. 2 is a schematic structural diagram of another embodiment of the present invention.

In the figure: 1. tube body; 2. observation cavity; 3. sputum suction channel; 4. oxygen injection channel; 5. miniature camera or optical fiber; 6. hole; 7. visual device; 8. tapered section.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

Referring to Figure 1 or 2, the sputum suction device in the figure includes a tube body 1 and a sputum suction channel 3 provided on the tube body 1, wherein: the tube body 1 is provided with an observation chamber 2 and an oxygen injection channel 4; The port of the observation cavity 2 at the sputum suction end of the tube body 1 is transparently closed, and the observation cavity 2 is provided with a miniature camera or an optical fiber 5 , and the other end of the miniature camera or the optical fiber 5 is connected to the signal output end of the visual device 7 . Through the visual device 7, it can be seen that the sputum suction end of the tube body 1 is inserted into the sputum accumulation position, which greatly reduces the blindness in the sputum suction operation process, and removes it in time, which greatly reduces the pain of the patient and can re-suction Oxygen operation is performed while sputum is being collected, which simplifies the operation process and further reduces the suffering of patients.

The suction end of the tube body 1 in the above structure has a tapered section 8 . Mechanical damage to the location of sputum accumulation is avoided.

The tube body 1 of this embodiment is a transparent tube body made of medical polymer materials. It is convenient for one-time use and achieves the purpose of sanitation.

The pipe wall of the tube body 1 at the suction end of the suction channel 3 of this structure is provided with a hole 6 communicating with the suction channel 3 . Facilitates quick suction.

The inner wall of the sputum suction channel 3 of this structure is coated with hydrophobic substances and antibacterial drugs. Facilitates smooth suctioning.

The tube wall of the tube body 1 at the suction end of the oxygen injection channel 4 in this embodiment is provided with a hole 6 communicating with the oxygen injection channel 4 . Facilitates rapid oxygen injection.

The micro-camera preferably has an outer diameter of 1.2mm. Ultra-miniature button camera from Wuhan Zhuoyue Electronics Co., Ltd.; FVY-680/780/980 milk duct endoscope from Beijing Bright Photoelectric Technology Development Co., Ltd.

The preferred outer diameter of the optical fiber is 0.5-1.0mm.

With the above structure, an oxygen injection machine can also be connected to the tail end of the oxygen injection channel 7 to ensure smooth breathing of the patient.

When this structure is manufactured, it is not limited to setting three cavities on a transparent tube made of medical polymer material, but can directly heat-bond three transparent tubes made of medical polymer material, one of which is a blind end , it is convenient to install a miniature camera or optical fiber inside.

To sum up, the present invention not only alleviates the patient's pain, reduces the patient's medical expenses and improves the work efficiency of the nursing staff, because the micro camera or the optical fiber is in the observation cavity, there is no pollution during use, and can be used many times use, saving costs.
