Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a sputum precision measuring device. Background Art

[0002] Patients with lung infections such as bleeding, long-term mechanical ventilation, tracheotomy, severe pneumonia, bronchiectasis, etc. have a large amount of sputum and frequent sputum suction operations. The amount of sputum becomes the second largest loss in their 24-hour output after urine, so patients need to be suctioned in a timely manner.

[0003] Sputum suction is the most basic and routine nursing intervention measure in patient airway management. The frequency of airway suction is determined by the viscosity, volume, and expectoration ability of the patient's sputum. In the treatment and nursing process of the disease, observing the amount, color, odor, properties, and abnormal substances of sputum has important clinical significance. There is no simple sputum measuring device for observing the amount of sputum in clinical practice. It is expected that there will be more accurate and easy-to-use measuring tools that can accurately measure the amount of sputum aspirated in a single time, so as to facilitate real-time recording and dynamic observation of sputum conditions, and ensure accurate real-time recording of the patient's 24-hour output. Therefore, a sputum precision measuring device is designed to solve the above problems. Utility Model Content

[0024] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0025] See also Figure 1-3 : A sputum precision measuring device, comprising a negative pressure tube 1, a sputum collecting bag 2, a connecting tube 1 3, a needle 4, a sputum measuring device, a connecting tube 2 7, a three-way tube 8, a sputum suction tube 9, a flushing tube 10 and an injection bottle 11, the right end of the negative pressure tube 1 is penetrated by a sputum collecting bag 2, the top of the sputum collecting bag 2 is penetrated by a connecting tube 1 3, the right end of the connecting tube 1 3 is connected to the sputum measuring device through the needle 4, the upper right of the sputum measuring device is connected to a connecting tube 2 7, the end of the connecting tube 2 7 is connected to a three-way tube 8, a channel of the three-way tube 8 is connected to a sputum suction tube 9, a channel of the three-way tube 8 is sleeved with a flushing tube 10, and an injection bottle 11 is sleeved above the flushing tube 10;

[0026] The sputum measuring device includes a measuring tube 5, a milliliter scale 501, a piston 6 and a through tube 601. The outer surface of the measuring tube 5 is engraved with a milliliter scale 501, the piston 6 is embedded above the measuring tube 5, a through tube 601 is penetrated on the right side of the upper surface of the piston 6, the needle 4 is inserted into the piston 6, and the connecting tube 7 is sleeved on the through tube 601.

[0027] During the sputum suction process, the sputum suction tube 9 is connected to the vocal syllable of a non-artificial airway patient or an artificial airway patient, and the sputum suction device connected to the negative pressure tube 1 is turned on. The sputum suction device generates negative pressure in the negative pressure tube 1, and the sputum of the patient is adsorbed into the measuring tube 5 for collection through the sputum suction tube 9, and the amount of sputum in the measuring tube 5 is observed through the milliliter scale 501 on the measuring tube 5. After the sputum suction is completed, the needle 4 is inserted into the inner bottom of the measuring tube 5. Under the action of the negative pressure of the negative pressure tube 1, the sputum in the measuring tube 5 enters the sputum collection bag 2 for collection, ensuring that there is no sputum in the measuring tube 5, so that the sputum suction amount can be determined by observing the measuring tube 5 when the sputum is adsorbed next time.

[0028] When it is necessary to flush the residual secretions in the suction tube 9, close the hose water stop clamp on the connecting tube 2 7, open the hose water stop clamp on the flushing tube 10, and facilitate the sterile injection water in the injection bottle 11 to enter the suction tube 9, thereby achieving the effect of cleaning the suction tube 9.

[0029] In this embodiment, the negative pressure tube 1 is connected to the suction end of the sputum suction device to facilitate the generation of negative pressure and sputum suction.

[0030] In this embodiment, the sputum collection bag 2 is made of hard plastic material to prevent the sputum collection bag 2 from shrinking due to negative pressure, and to ensure that the negative pressure tube 1 generates negative pressure through the sputum collection bag 2.

[0031] In this embodiment, hose water stop clamps are provided on connecting tube 2 7 and flushing tube 10 to facilitate closing of connecting tube 2 7 or flushing tube 10. When the hose water stop clamp on flushing tube 10 is closed, negative pressure tube 1, connecting tube 1 3, connecting tube 2 7 and sputum suction tube 9 form a negative pressure channel to facilitate sputum suction by sputum suction tube 9. Closing the hose water stop clamp on connecting tube 2 7 and opening the hose water stop clamp on flushing tube 10 facilitates the sterilized injection water in injection bottle 11 to enter into sputum suction tube 9, thereby achieving the effect of cleaning sputum suction tube 9.

[0032] In this embodiment, the length of the needle 4 is not less than the height of the measuring tube 5, so that the needle 4 can be inserted into the inner bottom of the measuring tube 5 to absorb the sputum at the inner bottom of the measuring tube 5.

[0033] In this embodiment, the measuring tube 5 is made of transparent plastic material, which is convenient for observing the amount of sputum in the measuring tube 5 .

[0034] In this embodiment, the injection bottle 11 contains sterile injection water.

[0035] The utility model makes full use of existing clinical materials, has low cost and is easy to operate. A sputum collection bag 2, a connecting tube 1 3, a needle 4, a sputum measuring device, a connecting tube 2 7, a three-way pipe 8 and a sputum suction tube 9 are connected to achieve the effect of continuous subglottic sputum suction for ordinary sputum suction patients, artificial airway sputum suction patients and closed sputum suction patients.

[0036] The device has a closed automatic flushing function, which can flush out the secretion liquid remaining in the suction tube 9 without disconnecting the connection, and the whole set of the device has good airtightness, which can effectively prevent the medical staff's hands from direct contact with secretions such as sputum, reduce the risk of occupational exposure, and is more conducive to preventing the occurrence of ventilator-associated pneumonia.

[0037] The amount of sputum in the sputum measuring device can be accurately determined and the amount of sputum suctioned within a specified time period can be observed, providing accurate reference data for doctors to judge the patient's condition and decide on treatment plans.
