Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, in particular to a sputum sampler used in a laboratory. Background Art

[0002] Sputum is the secretion of alveoli, bronchi and trachea. Sputum examination is of certain value in the diagnosis, efficacy observation and prognosis of respiratory diseases such as tuberculosis, lung fluke, lung tumors, bronchial asthma, chronic bronchitis, bronchiectasis and other diseases. At present, for those who have difficulty in coughing up sputum, medical staff often use negative pressure sputum samplers to suck out the viscous sputum from the throat of the subject. However, since the throat of the subject is difficult to observe, the medical staff only put the end of the sampler on the throat of the subject and start sucking sputum. At this time, the end of the sampler is in a blind field state. The medical staff can only judge whether it is placed in the correct position by whether the sampler can effectively suck sputum. The uncertainty is large, which affects the medical staff's rapid sputum sampling. Summary of the invention

[0003] Based on this, it is necessary to provide a sputum sampler for laboratory use to address the problem that the existing negative pressure sputum sampler used in the laboratory is difficult to accurately sample sputum, which affects the medical staff's rapid sputum sampling.

[0004] A sputum sampler for laboratory use, comprising a first elastic airbag and a sputum suction tube, one end of the first elastic airbag is fixedly connected and communicated with an air inlet check valve and an air outlet check valve, a visual field auxiliary device is sleeved on the surface of the sputum suction tube, characterized in that the sputum suction tube is plugged and communicated with one end of the air inlet check valve; Furthermore, the field of vision assist device includes a transparent flexible protective cover, an electronic laryngoscope and a reinforcing mechanism, the transparent flexible protective cover is sleeved on the surface of the suction tube, the electronic laryngoscope is inserted into the inner side of the transparent flexible protective cover, one end of the electronic laryngoscope passes through the outside of the transparent flexible protective cover, the reinforcing mechanism is fixedly connected and communicated with the surface of the transparent flexible protective cover, and one end of the reinforcing mechanism is fixedly connected and communicated with the air outlet one-way valve.

[0005] In one of the embodiments, the visual field assist device can integrate a common electronic laryngoscope with a suction tube, so that medical staff can accurately insert the suction tube into the sputum, thereby improving the efficiency of sputum sampling, and adopting a reinforcing mechanism used in conjunction with the sputum sampler, the medical staff can adjust the air pressure to tightly lock the transparent flexible protective cover and the electronic laryngoscope on the surface of the suction tube and the inside of the transparent flexible protective cover, respectively, which can make the electronic laryngoscope operate more stably, and adopt a negative pressure adsorption locking method, which will not squeeze the suction tube and the electronic laryngoscope, so as to ensure the normal operation of the suction tube and the electronic laryngoscope, and adopt a gas collection design, which can collect the extracted gas together, when the medical staff collects the test person who may have an infectious disease, this can concentrate the sputum and gas extracted from the patient's body in the sputum sampler, so as to facilitate centralized destruction after the test, thereby improving the safety factor of the sputum sampler.

[0006] Furthermore, a first air guide channel is provided inside the transparent flexible protective cover, and second air guide channels that are evenly distributed and connected to the first air guide channels are provided inside the transparent flexible protective cover. An adsorption hole connected to the adjacent second air guide channel is provided on the inner wall of the transparent flexible protective cover. The reinforcing mechanism includes a connecting tube, a piston cylinder piston plate and an adjusting rod. The connecting tube is fixedly connected to the surface of the transparent flexible protective cover, one end of the connecting tube is connected to the first air guide channel, the piston cylinder is plugged in and connected to the other end of the connecting tube, the piston plate is slidably connected to the inside of the piston cylinder, the adjusting rod is fixedly connected to one end of the piston plate, and one end of the adjusting rod passes through the outside of the piston cylinder.

[0007] In one of the embodiments, a negative pressure adsorption locking method is adopted, which will not squeeze the suction tube and the electronic laryngoscope, so as to ensure the normal operation of the suction tube and the electronic laryngoscope.

[0008] Furthermore, the reinforcement mechanism also includes a connecting tube, a push plate, a second elastic airbag and an air duct, the connecting tube is fixedly connected to one end of the piston cylinder, the adjusting rod is arranged on the inner side of the connecting tube, the push plate is fixedly connected to one end of the adjusting rod, the second elastic airbag is sleeved on the surface of the adjusting rod, the two ends of the second elastic airbag are respectively fixedly connected to the piston cylinder and the push plate, the second elastic airbag is in a stretched state at this time, the air duct is fixedly connected and connected to one end of the second elastic airbag, one end of the air duct passes through the piston cylinder and is plugged and connected to the air outlet one-way valve.

[0009] In one of the embodiments, a reinforcing mechanism is used in conjunction with a sputum sampler, and medical staff can adjust the air pressure to tightly lock the transparent flexible protective cover and the electronic laryngoscope on the surface of the suction tube and the inside of the transparent flexible protective cover, respectively. This can make the electronic laryngoscope operate more stably, and there is no need to design a separate driving source, thereby reducing the use cost of the sputum sampler.

[0010] Furthermore, the field of vision assisting device also includes evenly distributed rubber rings, which are not only fixedly connected to the surface of the transparent flexible protective cover, but are also sleeved on the surface of the suction tube, and the inner surface of the rubber ring is sleeved with a negative pressure cavity connected to the adjacent second air guide channel.

[0011] In one of the embodiments, this can make the connection between the transparent flexible protective sleeve and the suction tube more stable.

[0012] Furthermore, the adsorption holes are grouped into eight, each group of the adsorption holes is connected to the same second air guide channel, and the eight adjacent adsorption holes are distributed in a ring shape on the inner wall of the transparent flexible protective cover around the axis of the transparent flexible protective cover.

[0013] In one of the embodiments, this can improve the locking effect of the transparent flexible protective cover on the electronic laryngoscope through the adsorption hole, further ensuring the stable operation of the electronic laryngoscope.

[0014] Furthermore, the maximum movable distance of the piston plate in the piston cylinder is greater than the length of the connecting tube, and the length of the adjusting rod is greater than the maximum movable distance of the piston plate in the piston cylinder.

[0015] In one embodiment, this can ensure that after the piston plate is pushed into place, the second elastic airbag can still expand outward through the gap between the connecting tube and the push plate, ensuring that the gas can normally enter the second elastic airbag.

[0016] Furthermore, the ratio of the distance between the connecting tube and the push plate to the thickness of the second elastic airbag is five to one, and the corners of the connecting tube facing away from the piston cylinder are rounded.

[0017] In one embodiment, this further ensures that the gas can normally enter the second elastic airbag.

[0018] Furthermore, the diameter of the push plate is the same as the inner diameter of the connecting tube, and the corners of the push plate are rounded.

[0019] In one of the embodiments, this can ensure that the second elastic airbag cannot expand to the outside of the connecting tube when the push plate has not moved out of the connecting tube, thereby ensuring the locking effect of the electronic laryngoscope and the suction tube.

[0020] Furthermore, the blocking direction of the air inlet one-way valve is the same as the direction from the first elastic airbag to the sputum suction tube, and the blocking direction of the air outlet one-way valve is the same as the direction from the air outlet one-way valve to the first elastic airbag.

[0021] In one embodiment, this can ensure that the gas inside the first elastic airbag can only be squeezed out through the air outlet one-way valve, and the external gas can only be sucked into the first elastic airbag through the air inlet one-way valve.

[0022] Furthermore, one end of the air inlet one-way valve, the air outlet one-way valve, and the piston cylinder are all fixedly connected and connected with a pagoda female plug, one end of the suction tube, the other end of the connecting tube, and one end of the air guide tube are all fixedly connected and connected with a pagoda male plug, and the pagoda male plug is plugged into the inner side of the adjacent pagoda female plug.

[0023] In one of the embodiments, this enables the air inlet one-way valve and the suction tube, the air outlet one-way valve and the air guide tube, and the piston cylinder and the connecting tube to be disassembled and assembled according to needs, so as to facilitate subsequent precise maintenance or replacement by medical staff.

[0024] The above-mentioned sputum sampler used in the laboratory department, the field of view auxiliary device can provide medical staff with a real-time image of the end of the suction tube, so that the medical staff can accurately insert the suction tube into the sputum, thereby improving the sampling efficiency of the sputum. At the same time, the field of view auxiliary device is used in conjunction with the first elastic airbag, which can eliminate the structure of the field of view auxiliary device being driven separately, and can also make the operation of the electronic laryngoscope more stable, so that it can perform shooting operations more stably. In this process, a reinforcing mechanism is used to collect the extracted gas together. When medical staff collect the test subject who may have an infectious disease, this can concentrate the sputum and gas extracted from the patient's body in the sputum sampler for centralized destruction after the test, thereby improving the safety factor of the use of the sputum sampler. In addition, the above-mentioned negative pressure adsorption locking method will not squeeze the suction tube and the electronic laryngoscope, so that the suction tube and the electronic laryngoscope can remain in their original state, thereby achieving the purpose of ensuring the normal operation of the suction tube and the electronic laryngoscope.

[0033] Combine the following Figure 1 - Figure 8 The present invention is a sputum sampler for laboratory use.

[0034] In one embodiment, a sputum sampler for a laboratory comprises: a first elastic airbag 100, one end of which is fixedly connected to and communicated with an air inlet check valve 200 and an air outlet check valve 300, one end of which is plugged into and communicated with a sputum suction tube 400, and a visual field auxiliary device 500 is sleeved on the surface of the sputum suction tube 400; the visual field auxiliary device 500 comprises a transparent flexible protective cover 510, which is sleeved on the surface of the sputum suction tube 400, an electronic laryngoscope 520 is inserted into the inner side of the transparent flexible protective cover 510, and one end of the electronic laryngoscope 520 penetrates into the transparent flexible protective cover 510. 10, the surface of the transparent flexible protective cover 510 is fixedly connected and communicated with a reinforcing mechanism 530, and one end of the reinforcing mechanism 530 is fixedly connected and communicated with the air outlet one-way valve 300; the blocking direction of the air inlet one-way valve 200 is the same as the direction from the first elastic airbag 100 to the suction tube 400, and the blocking direction of the air outlet one-way valve 300 is the same as the direction from the air outlet one-way valve 300 to the first elastic airbag 100, which can ensure that the gas inside the first elastic airbag 100 can only be squeezed out through the air outlet one-way valve 300, and at the same time, the external gas can only be sucked into the first elastic airbag 100 through the air inlet one-way valve 200.

[0035] When the medical staff performs the sputum suction operation at a position convenient for observation, the medical staff only needs to connect the pagoda male plug 700 on the sputum suction tube 400 with the pagoda female plug 600 on the air inlet one-way valve 200, and then the sputum suction tube 400 can be placed in the sputum suction position, and then the medical staff presses the first elastic airbag 100, at which time the gas inside the first elastic airbag 100 is discharged to the outside through the air outlet one-way valve 300, and then the medical staff releases the first elastic airbag 100, at which time negative pressure is generated inside the first elastic airbag 100, and the first elastic airbag 100 extracts the air inside the sputum suction tube 400 through the air inlet one-way valve 200, and negative pressure is simultaneously generated inside the sputum suction tube 400, and the end of the sputum suction tube 400 draws sputum into it, and at this time the medical staff completes the sputum suction sampling of the person being tested, and then the sample can be sent for inspection normally; The visual field auxiliary device 500 can integrate the common electronic laryngoscope 520 with the suction tube 400, so that the medical staff can accurately insert the suction tube 400 into the sputum, thereby improving the sampling efficiency of the sputum, and adopting the reinforcing mechanism 530 used in conjunction with the sputum sampler, the medical staff can adjust the air pressure to lock the transparent flexible protective cover 510 and the electronic laryngoscope 520 tightly on the surface of the suction tube 400 and the inner side of the transparent flexible protective cover 510, respectively, which can make the electronic laryngoscope 520 operate more stably, and adopt the negative pressure adsorption locking method, which will not squeeze the suction tube 400 and the electronic laryngoscope 520, so as to ensure the normal operation of the suction tube 400 and the electronic laryngoscope 520, and adopt the gas collection design, which can collect the extracted gas together, when the medical staff collects the examinee who may suffer from an infectious disease, this can concentrate the sputum and gas extracted from the patient's body in the sputum sampler, so as to facilitate centralized destruction after the test, thereby improving the safety factor of the use of the sputum sampler.

[0036] like Figure 2 , Figure 3 , Figure 4 Figure 7 and Figure 8 As shown, the air inlet check valve 200, the air outlet check valve 300, and one end of the piston cylinder 532 are all fixedly connected and connected with a pagoda female plug 600, and one end of the suction tube 400, the other end of the connecting tube 531, and one end of the air guide tube 538 are all fixedly connected and connected with a pagoda male plug 700. The pagoda male plug 700 is plugged into the inner side of the adjacent pagoda female plug 600, which enables the air inlet check valve 200 and the suction tube 400, the air outlet check valve 300 and the air guide tube 538, and the piston cylinder 532 and the connecting tube 531 to be disassembled and assembled as needed, so as to facilitate subsequent precise maintenance or replacement by medical staff.

[0037] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, a first air guide channel 511 is provided inside the transparent flexible protective cover 510, second air guide channels 512 are evenly distributed and connected to the first air guide channels 511 are provided inside the transparent flexible protective cover 510, adsorption holes 513 connected to adjacent second air guide channels 512 are provided on the inner wall of the transparent flexible protective cover 510, and the reinforcing mechanism 530 includes a connecting tube 531, a piston cylinder 532, a piston plate 533 and an adjusting rod 534, the connecting tube 531 is fixedly connected to the surface of the transparent flexible protective cover 510, one end of the connecting tube 531 is connected to the first air guide channel 511, the piston cylinder 532 is plugged in and connected to the other end of the connecting tube 531, the piston plate 533 is slidably connected to the inside of the piston cylinder 532, the adjusting rod 534 is fixedly connected to one end of the piston plate 533, and one end of the adjusting rod 534 passes through the outside of the piston cylinder 532.

[0038] like Figure 4 , Figure 7 and Figure 8 As shown, the reinforcing mechanism 530 also includes a connecting tube 535, a push plate 536, a second elastic airbag 537 and an air guide tube 538. The connecting tube 535 is fixedly connected to one end of the piston cylinder 532. The adjusting rod 534 is arranged on the inner side of the connecting tube 535. The push plate 536 is fixedly connected to one end of the adjusting rod 534. The second elastic airbag 537 is sleeved on the surface of the adjusting rod 534. The two ends of the second elastic airbag 537 are fixedly connected to the piston cylinder 532 and the push plate 536 respectively. The bag 537 is in a stretched state at this time, and the air guide tube 538 is fixedly connected and connected to one end of the second elastic air bag 537. One end of the air guide tube 538 passes through the piston cylinder 532 and is plugged and connected to the air outlet one-way valve 300; the visual field auxiliary device 500 also includes evenly distributed rubber rings 540, which are not only fixedly connected to the surface of the transparent flexible protective cover 510, but also sleeved on the surface of the suction tube 400; the maximum movable distance of the piston plate 533 in the piston cylinder 532 is greater than the length of the connecting tube 535, and the length of the adjusting rod 534 is greater than the maximum movable distance of the piston plate 533 in the piston cylinder 532, which can ensure that after the piston plate 533 is pushed into place, the second elastic air bag 537 can still expand outward through the gap between the connecting tube 535 and the push plate 536, ensuring that the gas can enter the second elastic air bag 537 normally; the value of the distance between the connecting tube 535 and the push plate 536 and the thickness of the second elastic air bag 537 The ratio is five to one, and the corners of the connecting tube 535 facing away from the piston cylinder 532 are rounded, which further ensures that the gas can normally enter the second elastic airbag 537; the diameter of the push plate 536 is the same as the inner diameter of the connecting tube 535, and the corners of the push plate 536 are rounded, which can ensure that when the push plate 536 has not moved out of the connecting tube 535, the second elastic airbag 537 cannot expand to the outside of the connecting tube 535, thereby ensuring the locking effect of the electronic laryngoscope 520 and the suction tube 400.

[0039] like Figure 4 , Figure 5 and Figure 6 As shown, the inner surface of the rubber ring 540 is provided with a negative pressure cavity 541 connected to the adjacent second air guide channel 512, which can make the connection between the transparent flexible protective cover 510 and the suction tube 400 more stable; the adsorption holes 513 are grouped into eight, and each group of adsorption holes 513 is connected to the same second air guide channel 512, and the adjacent eight adsorption holes 513 are distributed in a ring shape on the inner wall of the transparent flexible protective cover 510 around the axis of the transparent flexible protective cover 510, which can improve the locking effect of the transparent flexible protective cover 510 on the electronic laryngoscope 520 through the adsorption holes 513, and further ensure the stable operation of the electronic laryngoscope 520.

[0040] Working principle: When the medical staff needs to go deep into the body of the examinee to perform suction operation, the medical staff first puts the rubber ring 540 on the surface of the suction tube 400, and then inserts the electronic laryngoscope 520 into the transparent flexible protective cover 510 until the electronic laryngoscope 520 is plugged into place, and then the medical staff plugs the pagoda male plug 700 on the suction tube 400 with the pagoda female plug 600 on the air inlet check valve 200, and then plugs the pagoda female plug 600 on the piston cylinder 532 with the pagoda male plug 700 on the connecting tube 531, and then plugs the pagoda male plug 700 on the air guide tube 538 with the pagoda female plug 600 on the air outlet check valve 300. At this time The medical staff then presses the first elastic airbag 100 back and forth, and the first elastic airbag 100 squeezes the gas inside it into the second elastic airbag 537 through the gas outlet one-way valve 300 and the air guide tube 538, and the second elastic airbag 537 expands accordingly, and the second elastic airbag 537 squeezes the push plate 536 outward, and the push plate 536 drives the adjustment rod 534 to move outward, and the adjustment rod 534 drives the piston plate 533 to move outward. At this time, negative pressure is generated inside the piston cylinder 532, and the piston cylinder 532 simultaneously extracts the gas inside the first air guide channel 511, the second air guide channel 512, the adsorption hole 513 and the negative pressure chamber 541 through the connecting tube 531. At this time, the adsorption hole 513 and the negative pressure chamber 541 simultaneously generate negative pressure. The suction hole 513 firmly absorbs the electronic laryngoscope 520 into the transparent flexible protective cover 510, and the negative pressure chamber 541 firmly locks the transparent flexible protective cover 510 onto the surface of the suction tube 400. This not only prevents the electronic laryngoscope 520 from sliding inside the transparent flexible protective cover 510 to ensure that the electronic laryngoscope 520 runs more stably, but also prevents the transparent flexible protective cover 510 from sliding on the surface of the suction tube 400, further improving the stability of the operation of the electronic laryngoscope 520. Then the medical staff can insert the suction tube 400, together with the transparent flexible protective cover 510 and the electronic laryngoscope 520, into the body of the examinee. The electronic laryngoscope 520 can be used to observe in real time whether the suction tube 400 is in contact with sputum. When the suction tube 400 enters the sputum, the medical staff presses the first elastic airbag 100. At this time, the gas inside the first elastic airbag 100 is discharged to the outside through the air outlet one-way valve 300. Then the medical staff releases the first elastic airbag 100. At this time, negative pressure is generated inside the first elastic airbag 100. The first elastic airbag 100 draws the air inside the suction tube 400 through the air inlet one-way valve 200. Negative pressure is simultaneously generated inside the suction tube 400. The end of the suction tube 400 draws sputum into it. At this time, the medical staff completes the suction sampling of the person being tested, and then the person can be sent for inspection normally.

[0041] It should be noted that the electronic laryngoscope 520, pagoda female plug 600 and pagoda male plug 700 in the above description are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs. At the same time, the electronic laryngoscope 520 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0042] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
