Description

Technical Field

[0001] The invention relates to the technical field of sputum suction, and more specifically to a sputum suction catheter for thoracic surgery nursing. Background Art

[0002] In the clinical treatment of thoracic surgery, the airway suction technology is not only to ensure the patient's airway is unobstructed and to absorb the sputum secreted in the airway. In most cases, especially for patients with a history of respiratory diseases, the biggest purpose of suctioning their sputum is actually to obtain sputum specimens, because the secreted sputum is very important for lung infectious diseases, especially for routine treatment. In order to provide an important basis for the selection of antibiotics and ensure that the infection can be controlled, it is very important to absorb qualified sputum specimens.

[0003] In the clinical nursing process, whether it is manual suction or suction through negative pressure adsorption equipment, a suction catheter is needed. The suction catheters on the market are usually made of polymer materials. After being connected to the suction source through a joint, suction can be performed. The whole is made of sterile materials and is a disposable adsorption tool.

[0004] However, this type of suction catheter cannot output the adsorbed sputum as a sputum specimen. This is because during the process of collecting sputum specimens, there are many microorganisms in the oral cavity, and the sputum may be contaminated by the microorganisms in the oral cavity. Therefore, the standard operation should be to gargle with light salt water before adsorption. This causes the adsorbed sputum to contain oral microbial saliva, gargle liquid, and even impurities such as gastric contents and blood. It is impossible to effectively collect qualified sputum specimens, and manual separation is required in the actual operation process to collect qualified sputum specimens.

[0005] Therefore, it is necessary to provide a sputum suction catheter for thoracic surgery nursing. Summary of the invention

[0006] Aiming at the problem that conventional sputum suction catheters in the prior art cannot effectively separate and collect qualified sputum specimens, the present invention aims to provide a sputum suction catheter for thoracic surgery nursing.

[0007] To solve the above problems, the present invention adopts the following technical solutions.

[0012] Optionally, a first convex spacer and a third convex spacer are respectively fixedly installed at the two ends of the outer circular surface of the arc clamping plate; a second convex spacer is fixedly installed at the middle of the outer circular surface of the arc clamping plate; and the arc clamping plate is slidably clamped in the inner guide rail groove through the convex spacers on three sides to fit tightly with the outer circular surface of the arc sleeve frame; and each convex spacer is provided with positioning circular openings on both sides for engaging with the reset spring buckle.

[0013] Optionally, threaded sleeves are fixedly installed on the surfaces of the first convex spacer, the third convex spacer and the second convex spacer; wherein the bottom inner sides of the threaded sleeves on the first convex spacer and the third convex spacer are respectively provided with leakage mesh sleeves; and the bottom inner sides of the threaded sleeves on the second convex spacer are in a through-opening state.

[0014] Optionally, outwardly extending handles are fixedly connected at both sides of the middle of the outer surface of the arc clamping plate, the opening size of the threaded sleeve is the same as the opening size of the reserved through hole, both sides of the sputum sorting bin are visible transparent structures, the outer side of the suction insertion tube interface is assembled with a corresponding suction tube, and the outer insertion end of the suction tube is provided with a soft rubber sleeve.

[0015] Optionally, the sputum collection mechanism includes a medical collection bottle, a threaded sleeve is fixedly installed on the outer surface of the medical collection bottle; and the medical collection bottle is rotatably installed on the threaded sleeves on the outside of the first convex spacer, the second convex spacer, and the third convex spacer through the threaded sleeve; each medical collection bottle is a transparent structure; and an adsorption catheter is inserted and installed on the other end face away from the threaded sleeve.

[0016] Optionally, a sealing mechanism is installed on the outer side of the medical collecting bottle near a position where a threaded sleeve is provided, and the sealing mechanism includes a square cavity grid, and U-shaped guide grooves are fixedly connected to the two sides of the square cavity grid that fits one end of the medical collecting bottle; and the U-shaped guide grooves penetrate into the interior of the medical collecting bottle; and are completely fitted with the inner wall of the medical collecting bottle.

[0017] Optionally, a T-shaped pull-out rod is sealed and inserted into the outer end surface of the square cavity grid, and a sealing partition is fixedly installed at the bottom of the T-shaped pull-out rod. The size of the sealing partition is the same as the inner cavity of the square cavity grid; and the same as the cross-sectional opening size of the medical collection bottle.

[0018] Optionally, lifting spacers are fixedly installed at the four side corners of one end surface where the medical collecting bottle and the adsorption catheter are connected; and the insertion end of each adsorption catheter is equipped with a corresponding one-way valve head.

[0019] Optionally, a fan scraper is movably installed at the internal axis position of the sputum sorting bin; and the three blades of the fan scraper are in close contact with the inner wall of the sputum sorting bin, and a support frame is movably installed on the outer surface of the sputum sorting bin; and a magnetic coating is attached to the bottom of the support frame.

[0020] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects:

[0021] In the above scheme, the sputum adsorbed by the suction tube can be reprocessed through the temporary storage and sorting function of the sputum sorting bin. It is only necessary to switch the sputum collection mechanisms with different interfaces to the reserved openings on the outer side of the sputum sorting bin through the switching mechanism, and then the sputum collection mechanisms at different end points can be aligned as needed to adsorb sputum in different states, and the impurity liquid in the oral or nasal cavity can be sorted and collected, effectively solving the problem that the conventional suction catheter in the prior art cannot effectively separate and collect qualified sputum specimens.

[0022] During the suction process, the external adsorption catheter and the corresponding adsorption source can make the corresponding medical collection bottle and the sputum sorting chamber have an inward adsorption force at the same time, which not only eliminates the need to repeatedly replace the collection end, thereby increasing the efficiency of daily suction care work in thoracic surgery, but also can utilize its adsorption force to drive the fan scraper in the sputum sorting chamber to rotate. On the one hand, it can scrape out the residual sputum on the inner wall of the sputum sorting chamber, and on the other hand, utilize its rotation effect and its fan blades to better guide the sputum out from the reserved opening.

[0023] Through the rotatable and detachable sputum collection mechanism configured on the switching mechanism, during the actual collection process, it can be directly rotated and disassembled for use as a single collection end. For example, the blood impurities in the adsorbed sputum can be stored separately to facilitate the subsequent provision of better test samples for lung infection detection. On the other hand, especially for the sputum sample collection end, during the visual adsorption operation, the qualified sputum can be directly switched to the collection end for collection, and its corresponding medical collection bottle can also be directly used as a sputum sample collection bottle, providing an important basis for the subsequent selection of antibiotics.

[0024] Through the sealing mechanism configured on the outer surface of the medical collection bottle, when the collection bottle collects qualified sputum, the sealing partition can be directly closed inward through the T-shaped pull rod to seal the outer port of the medical collection bottle to ensure that the collected qualified sputum samples are not contaminated, effectively prevent external bacteria from entering, and cause inaccurate test results to occur, thereby further improving the controllability and practicality of the sputum collection end in adsorbing sputum.

[0046] like Figures 1 to 7 As shown, an embodiment of the present invention provides a sputum suction catheter for thoracic surgery nursing, including a sputum sorting chamber 1, which is a table tennis racket-shaped cavity structure as a whole; and a sputum suction insertion tube interface 2 for connecting the catheter is fixedly installed at the position of the racket, and a side sliding positioning mechanism 4 and a switching mechanism 5 for the sliding sleeve on the side sliding positioning mechanism 4 are installed on the outer edge surface of the sputum sorting chamber 1.

[0047] Among them, the side-sliding positioning mechanism 4 includes an arc sleeve frame 41, which is a C-shaped arc structure as a whole, and one side of its C-shaped opening is opposite to the suction insertion tube interface 2; and a reserved opening 43 that passes through the sputum sorting chamber 1 is provided on the side of the surface of the arc sleeve frame 41 that is away from the suction insertion tube interface 2.

[0048] The switching mechanism 5 includes an arc clamping plate 51 slidably installed in a groove in the arc sleeve frame 41, and a plurality of sputum collecting mechanisms 6 corresponding to the reserved openings 43 are sequentially arranged on the outer surface of the arc clamping plate 51; the sliding arc clamping plate 51 is aligned with the sputum collecting mechanisms 6 at different end points as needed to absorb sputum in different states.

[0049] In order to solve the problem that conventional suction catheters in the prior art cannot effectively separate and collect qualified sputum specimens, the above-mentioned technical scheme is adopted to solve the problem. The above-mentioned technical scheme mainly includes a sputum sorting chamber 1, a side sliding positioning mechanism 4, a switching mechanism 5 and a sputum collecting mechanism 6, wherein the sputum sorting chamber 1 is used as a temporary storage component. After the sputum is adsorbed, the state of the internal sputum can be directly observed by relying on the visible structure on both sides of the sputum sorting chamber 1. In the early stage of adsorption, especially for patients with lung infectious diseases, it is necessary to collect qualified sputum samples at the same time as each sputum suction. In order to ensure that the collected sputum samples are qualified, the patient's oral cavity needs to be kept relatively clean, and if necessary, it is necessary to use light salt water to rinse the mouth before suctioning. This results in that in the early stage of adsorption, most of the adsorbed substances are impurity liquids secreted in the oral cavity or nasal cavity, and the impurity liquids cannot reflect the patient's lung infection. In this case, the sputum collecting mechanisms 6 at the two side positions can be switched through the switching mechanism 5 for collection to separate the impurity liquid. Because it has a filtering end, even if qualified thick sputum appears, it can be separated in the sputum sorting bin 1. When milky white or yellow sputum appears, the sputum collecting mechanism 6 at the middle position can be switched through the switching mechanism 5 for collection again. Because the sputum collecting mechanism 6 at the middle end is in a through-port state, the thick sputum can be adsorbed at one time. In special circumstances, such as when impurities similar to gastric contents, blood, etc. are adsorbed, the sputum collecting mechanism 6 at the other side end position can be switched through the switching mechanism 5 for collection again, so as to directly collect the characteristic sputum for subsequent detection. While the sputum suction is working, two groups of sputum samples to be detected can be synchronously collected to solve the problem that the conventional sputum suction catheter in the prior art cannot effectively separate and collect qualified sputum specimens.

[0050] like Figures 1 to 5 As shown, inner guide rail slots 42 are fixedly installed on both inner side surfaces of the arc sleeve 41, a sealing pad 57 is fixedly installed on one side surface of the arc clamping plate 51 that is attached to the slot of the arc sleeve 41, the length of the arc clamping plate 51 is one third of the length of the arc sleeve 41, and a reset spring buckle 44 is fixedly installed at a position exactly in the middle of both sides of the reserved through opening 43 on the inner guide rail slot 42.

[0051] Among them, the inner guide rail groove 42 is a circular guide rail groove surrounded by elastic sealing material, and its elastic sealing material includes but is not limited to fluororubber sealing rings, silicone rubber sealing rings and other sealing elastic materials. On the one hand, it is used to ensure that the inner side has a certain extrusion pressure, and on the other hand, it ensures the sealing of the sliding end.

[0052] like Figures 2 to 4As shown, the first convex spacer 52 and the third convex spacer 54 are fixedly installed at the two ends of the outer circular surface of the arc clamping plate 51; the second convex spacer 53 is fixedly installed at the middle of the outer circular surface of the arc clamping plate 51; and the arc clamping plate 51 is slidably clamped in the inner guide rail groove 42 through the convex spacers on three sides to fit tightly with the outer circular surface of the arc sleeve 41; and each convex spacer is provided with a positioning circular opening 55 on both sides for engaging with the reset spring buckle 44.

[0053] The first convex spacer 52, the third convex spacer 54 and the second convex spacer 53 have the same structure, except that the filter accessories arranged on the inner side of each convex spacer are different. The first convex spacer 52 and the third convex spacer 54 arranged on both sides can be configured with filter ends with a diameter that can allow normal secretions to pass through, and can filter out thick sputum, because thick sputum is often in block form.

[0054] like Figures 2 to 4 As shown, threaded sleeves 56 are fixedly installed on the surfaces of the first convex spacer 52, the third convex spacer 54 and the second convex spacer 53; wherein the inner bottoms of the threaded sleeves 56 on the first convex spacer 52 and the third convex spacer 54 are respectively provided with leakage net sleeves; and the inner bottoms of the threaded sleeves 56 on the second convex spacer 53 are in a through-opening state.

[0055] like Figures 1 to 4 As shown, the outer surface of the arc clamping plate 51 is fixedly connected with an outwardly extending handle bar 58 at both sides in the middle, the opening size of the threaded sleeve 56 is the same as the opening size of the reserved through hole 43, and the two sides of the sputum sorting bin 1 are both visible transparent structures. The outer side of the suction insertion tube interface 2 is assembled with a corresponding suction cannula 3, and the outer insertion end of the suction cannula 3 is provided with a soft rubber sleeve.

[0056] Among them, the size of the suction tube 3 can be determined according to the patient's oral or nasal cavity. An integrated suction tube consisting of a pipeline made of polymer material, a suction control device and a connector can be selected to ensure the overall sterility performance. It is a disposable accessory.

[0057] like Figures 1 to 4 As shown, the sputum collection mechanism 6 includes a medical collection bottle 61, and a threaded sleeve 62 is fixedly installed on the outer surface of the medical collection bottle 61; and the medical collection bottle 61 is rotatably installed on the threaded sleeve 56 on the outer sides of the first convex spacer 52, the second convex spacer 53, and the third convex spacer 54 through the threaded sleeve 62; each medical collection bottle 61 is a transparent structure; and the other end surface away from the threaded sleeve 62 is inserted and installed with an adsorption catheter 9.

[0058] Among them, the material of the adsorption catheter 9 is the same as that of the suction cannula 3 to ensure the overall sterility, and the soft rubber cover configured at one end of the suction cannula 3 inserted into the patient can be a latex gel cover to reduce the possibility of the insertion end damaging the patient's respiratory tract. The configured adsorption catheter 9 is externally connected to a medical adsorption source to accurately control its adsorption strength and time.

[0059] In order to solve the problem that conventional suction catheters in the prior art cannot effectively separate and collect qualified sputum specimens, the specific steps are as follows: first, a suction tube 3 with a suitable shape is made according to the thickness of the patient's oral cavity, and is assembled to one end of the suction insertion tube interface 2 for subsequent use, and then the adsorption catheter 9 is connected to the corresponding adsorption source, the suction tube 3 is inserted into the patient's oral cavity according to standard operations, and the adsorption source is turned on to perform the adsorption operation.

[0060] In the initial stage of adsorption: Since there are certain secretions in the patient's mouth, such as saliva, light salt water for gargling, and saliva, and this type of liquid only needs to be adsorbed out of the patient's airway, it cannot be used as a basis for later detection, and it will also interfere with the collection of normal sputum. Therefore, at this stage, the visual characteristics of the sputum sorting bin 1 can be used. When such liquid is adsorbed inside it, the arc card plate 51 is driven to slide along the inner guide groove 42 of the arc sleeve frame 41 by holding the extended hand-held rod 58, and the medical collection bottle 61 located on both sides of the outer surface of the arc card plate 51 is aligned with the reserved opening 43 of the sputum sorting bin 1. At this time, the first convex The spacer 52 or the third convex spacer 54 uses the filtering end at the bottom of its threaded sleeve 56 to align with the reserved opening 43, and is inserted into the positioning circular opening 55 of the second convex spacer 53 under the resetting and fixing action of the inner guide groove 42 and the resetting spring buckles 44 on both sides of the reserved opening 43 to position and fix it. At this time, the adsorption catheter 9 on the outside of the second convex spacer 53 is integrally connected with the sputum sorting bin 1 and the sputum suction cannula 3. Therefore, the oral secretion liquid adsorbed at this stage is collected in the medical collection bottle 61 at the side end of the arc card plate 51. Even if thick sputum appears, it can be blocked inside the sputum sorting bin 1 under the separation action of the filtering end.

[0061] In the late stage of adsorption: During this period, since the impurity liquid in the oral cavity has been adsorbed and transferred through the leakage hole at the filter end, what is adsorbed at this time is the sputum in the deep airway, and this type of sputum is generally thicker, usually milky white or yellow, and belongs to the sputum of qualified sputum specimens. Therefore, at this time, it is necessary to hold the extended hand-held rod 58 again to drive the arc clamping plate 51 to slide along the inner guide groove 42 of the arc sleeve frame 41, and align the second convex spacer 53 at the middle position of the outer surface of the arc clamping plate 51 with the reserved through hole 43. At this time, the medical collection bottle 61 with a through hole is aligned with the reserved through hole 43. At this time, adsorption is performed through the adsorption catheter 9, and the sputum inside the sputum sorting chamber 1 can be adsorbed, completing the sputum suction work while also completing the collection of qualified sputum specimens.

[0062] After collecting sputum in different states, the sputum can be transferred to the corresponding testing department for testing by unscrewing the medical collection bottle 61 outside the threaded sleeve 56, and the used accessories can be thrown into the corresponding trash can through standard operations.

[0063] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, a sealing mechanism 64 is installed on the outer side of the medical collecting bottle 61 near the position where the threaded sleeve 62 is provided. The sealing mechanism 64 includes a square cavity grid 641. The square cavity grid 641 is fixedly connected with U-shaped guide grooves 642 at both sides of the end of the medical collecting bottle 61; and the U-shaped guide grooves 642 penetrate into the interior of the medical collecting bottle 61; and are completely fitted with the inner wall of the medical collecting bottle 61.

[0064] like Figure 6 and Figure 7 As shown, a T-shaped pull-out rod 643 is sealed and inserted on the outer end surface of the square cavity grid 641, and a sealing partition 644 is fixedly installed on the bottom of the T-shaped pull-out rod 643. The size of the sealing partition 644 is the same as the inner cavity of the square cavity grid 641; and the same as the cross-sectional opening size of the medical collection bottle 61.

[0065] like Figures 3 to 7 As shown, lifting spacers 63 are fixedly installed at the four side corners of one end surface where the medical collection bottle 61 is connected to the adsorption catheter 9; and the insertion end of each adsorption catheter 9 is equipped with a corresponding one-way valve head.

[0066] Among them, the function of the configured one-way valve head is that during the adsorption process through the adsorption catheter 9, it can allow the gas to pass freely while blocking the passage of sputum. Because a catheter connector is configured at the bottom, the configured lifting spacer 63 is used to raise the height of the bottom of the medical collection bottle 61 so that the bottom can be placed stably when it is used as a storage bottle later.

[0067] like Figure 4 and Figure 5 As shown, a fan scraper 7 is movably installed at the internal axial position of the sputum sorting bin 1; and the three blades of the fan scraper 7 are all in contact with the inner wall of the sputum sorting bin 1, and a support frame 8 is movably installed on the outer surface of the sputum sorting bin 1; and a magnetic coating is attached to the bottom of the support frame 8.

[0068] During the standardized sputum specimen collection process, the collection end needs to avoid external interference, that is, to prevent external bacteria from interfering with the accuracy of the sputum specimen. Therefore, it is necessary to further optimize the sealing mechanism 64 before disassembly. Specifically, before disassembly, the sealing partition 644 stored in the square cavity grid 641 can be squeezed downward by holding the T-shaped pull rod 643, so that the sealing partition 644 extends along the inner wall of the U-shaped guide groove 642 to the front side of the medical collection bottle 61, and the sealing partition 644 is used to seal the front entrance of the medical collection bottle 61. At this time, the threaded sleeve 62 configured by the medical collection bottle 61 is turned down from the threaded sleeve 56 to ensure its relative sealing, so as to ensure the stability of the internal sputum specimen.

[0069] And during each adsorption process of the adsorption catheter 9, the adsorption force generated inside the sputum sorting chamber 1 can drive the fan scraper 7 inside the sputum sorting chamber 1 to rotate, and the scraper with the fit can further facilitate the sputum discharge.

[0070] The method of use provided by the present invention is as follows:

[0071] When the present invention is used, firstly, a suction cannula 3 of a corresponding size is selected according to the coarseness of the patient's oral cavity, and assembled on the suction insertion tube interface 2. Then, a corresponding adsorption catheter 9 is connected to the outside of each medical collection bottle 61, and the adsorption source is turned on. The suction cannula 3 is inserted into the patient's oral cavity for adsorption according to the specification. During the adsorption process, the sputum adsorbed inside the sputum sorting bin 1 is observed to select different sputum collection mechanisms 6 for collection. The switching mechanism 5 is slid on the outside of the side-sliding positioning mechanism 4 to switch and align the medical collection bottles 61 at different positions. The separated medical collection bottles 61 are used for classification and collection, and the interfering liquid can be discharged first and then the qualified sputum can be collected, so as to solve the problem that the conventional suction catheter in the prior art cannot effectively separate and collect qualified sputum specimens.

[0072] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0073] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
