Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of tumor nursing and relates to a nasopharyngeal washing nursing device for an oncology department. Background Art
[0002] In clinical nursing of the oncology department, nasopharyngeal irrigation is a common and important nursing operation, especially for cancer patients who receive nasopharyngeal radiotherapy, or have complications such as nasopharyngeal infection and increased secretions. Regular nasopharyngeal irrigation can effectively clear the secretions, necrotic tissue and pathogenic bacteria in the nasal cavity and nasopharynx, reduce mucosal edema, relieve nasal congestion, runny nose and other uncomfortable symptoms, prevent the infection from worsening, and promote patient recovery.
[0003] However, most of the existing nasopharyngeal irrigation care devices on the market have relatively simple functions. In terms of irrigation mode, the traditional manual pressing design is usually adopted. This operation mode has mechanical characteristics limitations such as large pressure fluctuations and unstable single liquid output. It is difficult to flexibly switch between pulse irrigation and continuous irrigation mode according to the patient's actual condition and tolerance. For example: For patients with sensitive nasal cavity or fragile mucosa, pulse irrigation can avoid continuous high-pressure stimulation; and for cases of severe blockage, continuous irrigation mode can improve cleaning efficiency. The traditional manual pressing operation not only increases the intensity of care, but also makes it difficult to achieve precise regulation of irrigation pressure. Summary of the Invention

[0031] 4. The nasopharyngeal irrigation nursing device for oncology disclosed in the present invention has a first fixing seat, a pin and a first spring on the top wall of the mounting frame, and a positioning groove for cooperating with the pin is opened on the outer wall of the bottom end of the turntable. After the nasal cavity on one side is cleaned, the turntable is rotated to adjust the position of the fixed tube until the pin is stuck in the corresponding positioning groove, so that the turntable can be accurately positioned, which can ensure that the position of the nozzle is accurate when flushing the other nasal cavity, thereby improving the accuracy and stability of flushing and ensuring the consistency of the flushing effect.
[0032] 5. The oncology nasopharyngeal irrigation care device disclosed in the present invention can realize intermittent irrigation mode by cooperating with the piston tube through the driving mechanism and the piston tube, and can also be switched to continuous irrigation mode, in which the cleaning liquid is intermittently pushed into the nasal cavity by the reciprocating pushing component, and can be driven by the transmission component to rotate the first piston rod to continuously squeeze out the cleaning liquid to meet different irrigation needs.

[0046] The following describes the embodiments of the present invention by means of specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and the following embodiments and features in the embodiments can be combined with each other without conflict.
[0047] like Figures 1-10The nasopharyngeal irrigation nursing device for oncology shown includes a mounting frame 1, a piston tube 5, a driving mechanism and a cleaning mechanism. The driving mechanism switches the intermittent or continuous irrigation mode, and the cleaning mechanism automatically cleans the nozzle during the irrigation interval.
[0048] The mounting frame 1 serves as the supporting structure for the entire device. A turntable 2 is mounted on its top, rotatably mounted via bearings. A first connecting pipe 3 is fixedly mounted on top of the turntable 2, and a water collection hopper 4 for collecting wastewater is mounted on top of the first connecting pipe 3. A sewage tank 11 is inserted into the mounting frame 1. A drain pipe 12 is mounted on the bottom of the turntable 2, rotatably mounted via bearings, and connected to the sewage tank 11. Wastewater generated during patient flushing is collected by the water collection hopper 4 and then discharged into the sewage tank 11 through the first connecting pipe 3 and drain pipe 12.
[0049] The piston tube 5 is fixed to the top of the turntable 2 by two second fixing seats 17. One end of the piston tube 5 is threadedly connected to the first piston rod 18, and the other end is slidably connected to the second piston rod 19. The middle section of the piston tube 5 is connected to the fixed tube 7, and the top of the fixed tube 7 extends into the water collecting bucket 4. A hose 8 is slidably arranged in the fixed tube 7, and a nozzle 9 is connected to the top of the hose 8. The cleaning liquid is sprayed into the patient's nasal cavity through the nozzle 9 for flushing. When the hose 8 is located in the fixed tube 7, the fixed tube 7 can be used to support the nozzle 9 so that no bending displacement occurs. The nozzle 9 and the hose 8 are connected in a detachable manner, and nozzles of different sizes can be replaced. A clean water box 6 connected to the piston tube 5 is also provided on the top of the turntable 2 for storing cleaning liquid. A heating wire is also provided in the clean water box 6 to heat the cleaning liquid inside so that the temperature is moderate.
[0050] A drive mechanism is mounted on the turntable 2, driving the cleaning fluid within the piston tube 5. The drive mechanism comprises a reciprocating push assembly and a transmission assembly. The drive mechanism includes a transmission rod 25, which rotates within two second fixed seats 17 via bearings. A motor 26 is bolted to the top of the turntable 2, with the output end of the motor 26 welded to the transmission rod 25.
[0051] The reciprocating push assembly includes a first retaining ring 21 welded to one end of the piston tube 5. A second retaining ring 22 is sleeved on the outer wall of the second piston rod 19, which cooperates with the first retaining ring 21. A third fixing seat 23 is rotatably mounted between the second retaining ring 22 and the outer wall of the first piston rod 18 via a bearing. A first gear ring 24 is also sleeved on the outer wall of the second retaining ring 22 and the first piston rod 18. A gear 32 is rotatably mounted on one side of the third fixing seat 23 via a bearing, meshing with the first gear ring 24. The first gear ring 24, located on the second retaining ring 22, is welded to the second retaining ring 22. The gear 32, located below the second retaining ring 22, is slidably mounted on the transmission rod 25 via a first slide groove and a slider, and is in transmission connection with the transmission rod 25. The outer wall of the second piston rod 19 is sleeved with a second spring 20, which is located within the piston tube 5. In addition, a first sliding ring 28 is provided on the outer wall of the transmission rod 25, and a rotating ring 29 is provided on the outer wall of the first sliding ring 28 through a bearing. An insertion rod 31 is inserted into one side of the rotating ring 29, and the insertion rod 31 is welded to one end of the first retaining ring 21. A first guide rod 30 is welded to one side of the piston tube 5, and the rotating ring 29 is slidably sleeved on the first guide rod 30.
[0052] The transmission assembly includes a plurality of second guide rods 44 welded to one side of the gear 32 below the first piston rod 18. A fourth retaining ring 35 is slidingly sleeved on the outer wall of the plurality of second guide rods 44. A second sliding ring 33 is welded to the outer wall of the transmission rod 25, and a third retaining ring 34 is welded to one side of the second sliding ring 33 for use with the fourth retaining ring 35. A sliding rod 27 is slidingly mounted within the transmission rod 25. A stud 36 is rotatably mounted at one end of the sliding rod 27 via a bearing. The stud 36 is threadedly connected to one end of the transmission rod 25. Two sets of rectangular holes 37 are formed in the outer wall of the transmission rod 25. Sliding blocks 38 are slidingly mounted within the rectangular holes 37. The first sliding ring 28 and the fourth retaining ring 35 are welded to the two sets of sliding blocks 38, respectively.
[0053] By starting the motor 26, the motor 26 drives the transmission rod 25 to rotate. The rotation of the transmission rod 25 drives the first sliding ring 28 to rotate, which in turn drives the gear 32 on the left to rotate. The gear 32 drives the second retaining ring 22 to rotate through the first gear ring 24. During the rotation process, the second retaining ring 22 moves outward due to the action of the first retaining ring 21, driving the second piston rod 19 to move outward. When the teeth of the second retaining ring 22 correspond to the tooth grooves of the first retaining ring 21, the second piston rod 19 resets and moves under the action of the second spring 20, and at the same time drives the teeth on the second retaining ring 22 to engage with the tooth grooves on the first retaining ring 21, realizing the reciprocating movement of the second piston rod 19. When the second piston rod 19 moves inward, it squeezes out the cleaning liquid in the piston tube 5; when it moves outward, it draws the cleaning liquid in the clean water box 6 into the piston tube 5, realizing intermittent flushing. When continuous flushing is required, the stud 36 is rotated, and the stud 36 drives the sliding rod 27 to move outward. The sliding rod 27 drives the fourth snap ring 35 and the first sliding ring 28 to move to the right through the two sets of sliding blocks 38, so that the insertion rod 31 is disengaged from the rotating ring 29, and the fourth snap ring 35 is engaged with the third snap ring 34. At this time, the motor 26 is started to drive the transmission rod 25 to rotate, and the gear 32 on the right side is driven to rotate through the engaged third snap ring 34 and fourth snap ring 35. The gear 32 drives the first piston rod 18 to rotate. The first piston rod 18 uses the outer external thread and the inner thread of the piston rod 5 to move in the piston tube 5, continuously pressurizing the liquid in the piston tube 5, realizing continuous extrusion of the liquid, so that continuous and intermittent adjustment can be conveniently performed.
[0054] Among them, the shape of the nozzle 9 can adopt the following forms according to clinical needs: 1. Conical tapered nozzle: the front end is designed with a cone angle of 15°~30°, which is suitable for deep nasopharyngeal irrigation and can directionally guide the irrigation liquid flow to penetrate the secretion blockage area; 2. Spherical porous nozzle: 8-12 radial micropores with an aperture of 0.5-1mm are distributed on the surface to form an atomized irrigation mode, reducing the impact pressure of the mucosa, which is especially suitable for sensitive patients after surgery; 3. Ellipsoid lateral nozzle: 3 groups of fan-shaped injection ports are opened in the long axis direction, and the irrigation liquid is diffused in a 120° fan shape, which can simultaneously clean the nasal concha and the side walls of the nasal passage; 4. Porous umbrella-shaped nozzle: after unfolding, an umbrella-shaped injection surface with a diameter of 8-15mm is formed, and the hole positions are distributed in concentric circles to achieve full coverage irrigation of the nasal cross section.
[0055] The cleaning mechanism is arranged on the turntable 2 and is used to clean the nozzle 9 after use. The cleaning mechanism includes a cleaning box 10 arranged on the top of the turntable 2, and a cleaning cup 39 is arranged in the cleaning box 10 through a bearing rotation (a quick-release buckle structure is used to install bristles of different hardness (soft bristles / hard bristles / silicone heads), adapted to the surface material of the nozzle 9), and a brush is arranged in the cleaning cup 39. The cleaning cup 39 is connected to the third fixed seat 23 on the second retaining ring 22 through a transmission member, and the cleaning box 10 is connected to the drain pipe 12 through a pipe. The transmission member includes a second gear ring 40 fixed on the outer wall of the cleaning cup 39, a slide groove 43 is opened on one side of the cleaning box 10, and a connecting rod 42 is slidably arranged in the slide groove 43, one end of the connecting rod 42 is engaged with the rack 41, and the other end is welded to one side of the third fixed seat 23 close to each other.
[0056] When the nozzle 9 needs to be cleaned and disinfected, the heating wire in the clean water box 6 is activated to heat the liquid inside and boil it. Then, the motor 26 is activated to squeeze the water out of the clean water box 6, and the nozzle 9 is placed into the cleaning cup 39 in the cleaning box 10. The boiling water flows out, cleaning and disinfecting the nozzle 9. Simultaneously, the reciprocating motion of the second piston rod 19 drives the rack 41 through the connecting rod 42. The rack 41, in turn, rotates the cleaning cup 39 via the second gear ring 40, cleaning the outer wall of the nozzle 9.
[0057] Two first fixing seats 14 are welded to the top wall of the mounting frame 1. A pin 15 is provided on one side of the first fixing seat 14. A first spring 16 is sleeved on the outer wall of the pin 15. The two ends of the first spring 16 are respectively fixedly connected to the outer wall of one end of the pin 15 and one side of the first fixing seat 14. The outer wall of the bottom end of the turntable 2 is provided with a positioning groove 13 for use with the two pins 15. After cleaning one side of the nasal cavity, the turntable 2 is rotated to adjust the position of the fixing tube 7 until the pin 15 is snapped into the corresponding positioning groove 13, completing the positioning of the turntable 2 so that the other side of the nasal cavity can be cleaned.
[0058] When using the oncology nasopharyngeal irrigation nursing device, the prepared cleaning water is poured into the clean water box 6, and the cleaning water in the clean water box 6 flows into the piston tube 5 through the pipe; then the mounting frame 1 is moved in front of the patient on the bed, the patient's nose is lowered, and the nozzle 9 is inserted into the patient's nostril;
[0059] When the motor 26 is started, the motor 26 can drive the transmission rod 25 to rotate. The rotation of the transmission rod 25 can drive the first sliding ring 28 to rotate, which can drive the gear 32 on the left side to rotate. The rotation of the gear 32 can drive the second snap ring 22 to rotate through the first gear ring 24. During the rotation, the second snap ring 22 can push the second snap ring 22 to move outward through the first snap ring 21, which can drive the second piston rod 19 to move outward. When the teeth of the second snap ring 22 correspond to the tooth grooves of the first snap ring 21, the second piston rod 19 can be reset and moved under the action of the second spring 20, and drive the teeth on the second snap ring 22 to fit into the tooth grooves on the first snap ring 21, thereby driving the second piston rod 19 to reciprocate. During the inward movement of the second piston rod 19, the cleaning liquid in the piston tube 5 can be squeezed out, and during the outward movement of the second piston rod 19, the cleaning liquid in the clean water box 6 can be drawn into the piston tube 5, performing intermittent flushing in sequence;
[0060] When continuous flushing is required, the stud 36 is turned. During the rotation of the stud 36, the sliding rod 27 can be driven to move outward. The movement of the sliding rod 27 can drive the fourth snap ring 35 and the first sliding ring 28 to move to the right through the two sets of sliding blocks 38, so that the insertion rod 31 is disengaged from the rotating ring 29 and the fourth snap ring 35 is engaged with the third snap ring 34. At this time, the motor 26 is started to drive the transmission rod 25 to rotate, which can drive the right gear 32 to rotate through the two engaged third snap rings 34 and fourth snap rings 35. The rotation of the gear 32 can drive the first piston rod 18 to rotate. The rotation of the first piston rod 18 can utilize the external thread on its outer side and the internal thread in the piston rod 5 to move it in the piston tube 5, thereby continuously pressurizing the liquid in the piston tube 5 and continuously squeezing out the liquid;
[0061] After the nasal cavity on one side is cleaned, the position of the fixed tube 7 can be adjusted by rotating the turntable 2 until the pin 15 is snapped into the corresponding positioning groove 13, and the adjustment is completed;
[0062] When the nozzle 9 needs to be cleaned and disinfected, the heating wire in the clean water box 6 can be started to heat and boil the liquid inside, and then the water in the clean water box 6 can be squeezed out by starting the motor 26. At the same time, the nozzle 9 is placed in the cleaning cup 39 in the cleaning box 10. During the boiling water flowing out, the nozzle 9 can be cleaned and disinfected. At the same time, during the reciprocating movement of the second piston rod 19, the rack 41 can be driven to move through the connecting rod 42. The movement of the rack 41 can use the second gear ring 40 to drive the cleaning cup 39 to rotate, so that the outer wall of the nozzle 9 can be cleaned.
