Sputum aspirator
Technical field
This utility model relates to a kind of clinical treatment equipment, and especially a kind of collection is inhaled expectorant and annotated oxygen, safe sputum aspirator.
Background technology
Many clinically patients expectoration voluntarily needs the artificial auxiliary expectorant of inhaling, and to keep the unobstructed of respiratory tract, is convenient to pulmonary ventilation.Therefore inhaling expectorant with sputum aspirator is a kind of medical apparatus commonly used in the clinical treatment.
Inhale expectorant in the prior art, Oxygen uptaking catheter is single chamber, when needs of patients is inhaled expectorant, oxygen uptake, adopt and insert two conduits, the patient is inserted the damage that conduit can directly cause tunica mucosa tracheae repeatedly, comprise that congestion and edema, epithelium strip off, cilium is lost and granuloma forms, and increase the chance of patient's bleeding and infection, also often cause patient's hypoxemia because of irritable cough or oxygen supply deficiency.And in use, judge where be inserted into, safety is low according to experience by the medical worker.
And in the prior art suction catheter inserted shallow, then can only be with air flue top sputum exhaustion, thorough whole sputums of sucking-off, the sputum in its trachea deep easily forms expectorant crust obstruction air flue or causes the intrapulmonary infection complication.Can inhale expectorant by photopic vision under laryngoscope or fibre bronchus mirror's guiding, but the former can only observe the part air flue, expectorant is inhaled in the deep does not have help yet, and the latter needs to carry out on the local anaesthesia basis, complex operation, the two required expense costliness of while, and require high to medical worker's technical merit.
In sum, the sputum aspirator function singleness of prior art has increased patient's misery and expense in the use, and operator's operant skill is required than higher, and safety is low.
Summary of the invention
The purpose of this utility model is in order to overcome the prior art above shortcomings, a kind of collection suction expectorant to be provided and to annotate oxygen, minimizing patient suffering, and sputum aspirator easy to use and the raising safety.
This utility model is achieved through the following technical solutions, and a kind of sputum aspirator comprises body and is arranged on suction expectorant passage on the body, and wherein: described body is provided with observation chamber and annotates the oxygen passage; Described observation chamber is transparent sealing at the port of the suction expectorant end of body, is provided with minisize pick-up head or optical fiber in the observation chamber, and an other end of minisize pick-up head or optical fiber is connected with the signal output part of visual device.
This utility model is owing to the advantage that has adopted said structure to have is: owing to have visuality, reduced blindness in inhaling the expectorant operating process greatly, can find long-pending expectorant position rapidly accurately, and get rid of timely, reduced patient's misery greatly, carry out oxygen supply operation when can inhale expectorant again, and simple to operate and do not increase other operation requirement on existing basis of inhaling the expectorant technology.
Description of drawings
This utility model can further specify by the indefiniteness embodiment that accompanying drawing provides.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an another example structure sketch map of the present utility model.
Among the figure: 1, body; 2, observation chamber; 3, inhale the expectorant passage; 4, annotate the oxygen passage; 5, minisize pick-up head or optical fiber; 6, hole; 7, visual device; 8, conical section.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Referring to accompanying drawing 1 or 2, the sputum aspirator among the figure comprises body 1 and is arranged on suction expectorant passage 3 on the body 1, and wherein: described body 1 is provided with observation chamber 2 and annotates oxygen passage 4; Described observation chamber 2 is transparent sealing at the port of the suction expectorant end of body 1, is provided with minisize pick-up head or optical fiber 5 in the observation chamber 2, and an other end of minisize pick-up head or optical fiber 5 is connected with the signal output part of visual device 7.Can see that by visual device 7 the suction expectorant end of body 1 inserts long-pending expectorant position, reduced the blindness in inhaling the expectorant operating process greatly, and get rid of timely, reduced patient's misery greatly, carry out the oxygen supply operation when can inhale expectorant again, simplify the operation course, further reduce the patient suffering.
The suction expectorant end of the body 1 in the said structure has conical section 8.Avoided mechanical wounding to long-pending expectorant position.
The transparent tube body of body 1 for adopting medical macromolecular materials to make of present embodiment.Be convenient to disposable use, reach the purpose of health.
The tube wall of the suction expectorant end body 1 of the suction expectorant passage 3 of this structure is provided with and inhales the hole 6 that expectorant passage 3 communicates.Be convenient to inhale fast expectorant.
The inwall of the suction expectorant passage 3 of this structure scribbles hydrophobic substance and antibacterials.It is smooth and easy to be convenient to inhale expectorant.
The tube wall of the suction expectorant end body 1 of the notes oxygen passage 4 of present embodiment is provided with and annotates the hole 6 that oxygen passage 4 communicates.Be convenient to annotate fast oxygen.
Described body 1 is three integral body that the single-pass deferent is combined into.
The inwall of described suction expectorant passage 3 has hydrophobic coating or/and the antibacterials coating.
Described minisize pick-up head, preferred external diameter is 1.2mm.Adopt the remarkable Electronics Co., Ltd. in Wuhan, superminiature button photographic head; BeiJing BoLaiDe opto-electrical Technology Development Co., Ltd FVY-680/780/980 milk duct endoscope.
The preferred external diameter 0.5-1.0mm of described optical fiber.
Said structure can also connect Oxygen injecting machine at the tail end of annotating oxygen passage 7, guarantees that patient respiration is smooth and easy.
This structure during fabrication, be not limited on the transparent tube that medical macromolecular materials are made, be provided with three chambeies, the transparent tube heat seal that can directly three medical macromolecular materials be made is an one, and wherein one is cecum, dress minisize pick-up head or optical fiber in being convenient to.
In sum, this utility model not only alleviated patient misery, reduced patient medical expense and improved nursing staff's work efficiency because minisize pick-up head or optical fiber in observation chamber, in use do not pollute, can repeatedly use, save cost.
