Description

Technical Field

[0001] The utility model relates to the technical field of critical care nursing equipment, and in particular to a drainage device for critical care nursing. Background Art

[0002] The Department of Intensive Care Medicine (ICU) is an important part of our hospital. It is mainly responsible for the centralized treatment of all kinds of critically ill patients from all departments of the hospital. Through close observation, timely and effective treatment and meticulous care, patients can be out of danger and recover in a short time. It often creates some medical miracles and is known as the "holy place for miracles". After thoracic surgery, patients need to use a nursing drainage device to drain the effusion in the patient's chest cavity through negative pressure drainage.

[0003] When traditional nursing drainage devices are used to drain patients, the patient's family members or doctors need to enter the patient's ward several times to check the drainage situation to prevent the drainage bottle from being replaced in time after it is full, which may cause danger. This is relatively time-consuming and labor-intensive, and has low efficiency, resulting in unnecessary workload. When the drainage tube is connected to the patient's chest tube and placed on the bed, the patient is prone to unconsciously press on the drainage tube, which may cause drainage blockage, which is relatively dangerous.

[0004] In order to solve the above problems, a nursing drainage device for critical care medicine is disclosed in a patent document with announcement number "CN215386317U", which relates to the field of medical device technology, including a drainage tube, one end of the drainage tube is fixedly connected to a connector, and the other end of the drainage tube is fixedly connected to a main drainage bottle, the outer end of the drainage tube is sleeved with an anti-pressure mechanism, the outside of the main drainage bottle is sleeved with a storage reminder device, and the side of the main drainage bottle is located inside the storage reminder device and is connected to an auxiliary drainage bottle through a pipeline; the utility model provides that, through the storage reminder device, when the liquid in the auxiliary drainage bottle reaches the rated weight collected, it is sensed by the pressure sensor on the extrusion plate, and the information is transmitted to the hospital control system through the wire, reminding the nurse station doctor to replace it, which is relatively time-saving and labor-saving, does not require manual supervision, improves the inspection efficiency, and solves the problem of requiring patients' family members to check multiple times or doctors to enter the patient's ward multiple times to check the drainage situation.

[0005] In the above-mentioned prior art, although the problem of the drainage tube being easily blocked by pressure is solved by means of a sleeve-type anti-pressure mechanism, since the sleeve-type anti-pressure mechanism has no unlimited structure on the drainage tube, the anti-pressure mechanism and the drainage tube are easily affected by external forces and cause relative displacement, which is disadvantageous when a certain part needs to be protected from pressure. Therefore, a drainage device for critical care nursing is needed. Utility Model Content

[0006] The purpose of the present application is to provide a drainage device for critical care nursing to solve the problems raised in the above-mentioned background technology.

[0008] The protective structure includes a first anti-pressure block, a second anti-pressure block and an elastic band, two first anti-pressure blocks are provided and are mirror-imaged along the cross-section of the drainage tube, a plurality of second anti-pressure blocks are provided and are evenly distributed between the two first anti-pressure blocks, and the elastic band is fixedly connected between two adjacent second anti-pressure blocks or between the second anti-pressure block and the first anti-pressure block;

[0009] The first pressure-proof block includes an elastic sleeve and an air bag, wherein the elastic sleeve is fixedly embedded in the through hole in the middle of the support block, the elastic sleeve is movably sleeved on the drainage tube, the air bag is fixed to one end of the elastic sleeve, and the air bag is fixed to the inner wall of the support block;

[0010] The first anti-pressure block is provided with an adjusting structure for inflating or relieving pressure in the airbag.

[0011] Preferably, an air inlet nozzle is fixed and connected to one side of the airbag;

[0012] The regulating structure comprises a regulating bolt and a through hole. The other end of the air inlet nozzle is connected with the through hole. The regulating bolt is screwed into the through hole. The regulating bolt is close to the air inlet nozzle to form a sealing plug and seal with the inner wall of the through hole.

[0013] Preferably, the through hole is a threaded hole, and the adjusting bolt is provided with a threaded portion adapted to the threaded hole.

[0014] Preferably, an air cavity connected to the threaded hole is provided on the support block, a piston plate slides in the air cavity, and the peripheral side of the piston plate forms a seal with the inner wall of the air cavity;

[0015] One end of the adjusting bolt abuts against a side of the piston plate away from the air inlet nozzle.

[0016] Preferably, the end of the adjusting bolt is rotatably connected to a side of the piston plate away from the air inlet nozzle.

[0017] Preferably, the airbag is interference fit with the outer wall of the drainage tube after being filled with gas, and the minimum inner diameter of the airbag is smaller than the outer diameter of the drainage tube after being filled with gas.

[0018] In summary, the technical effects and advantages of the utility model are:

[0019] 1. In the utility model, through the arrangement of the airbag and the adjustment structure, after the protective structure is sleeved on the drainage tube, if a certain section of the drainage tube needs to be pressure-proofed, the user only needs to pull the first pressure-proof blocks at both ends to drive the multiple second pressure-proof blocks in the middle section to move synchronously, so that the protective structure moves to a predetermined position as a whole. At this time, the user only needs to inflate the airbag through the adjustment structure to make the airbag deform and bulge inward, so that the inner wall of the airbag and the outer wall of the drainage tube have an interference fit, and the position of the drainage tube and the airbag can be adjusted by the friction between the airbag and the drainage tube. The position is relatively fixed. At this time, the airbag fixes the position of the first anti-pressure block. When the positions of the two first anti-pressure blocks at both ends are fixed, the positions of the multiple second anti-pressure blocks in the middle section are also limited within a certain range, so that the protective structure as a whole can be fixed on a certain section of the drainage tube and is not easily moved by external forces. Therefore, it can provide stable and effective anti-pressure protection for the section of the drainage tube that needs anti-pressure protection, improve the stability of the anti-pressure protection of the drainage tube, and is more conducive to playing a stable and effective anti-blockage role in the use of the drainage device for critical care nursing.

[0020] 2. In the utility model, the volume of the gas pressed into the airbag can be further increased by setting the air cavity and the piston plate, ensuring that the airbag can hold the drainage tube well after deformation. At the same time, the piston plate can be used in conjunction with the adjusting bolt to prevent air from escaping from the gap between the adjusting bolt and the threaded hole. On the premise of ensuring that the position of the adjusting bolt can be self-fixed, it is further ensured that the gas in the airbag will not escape. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example: Reference Figure 1-4 The drainage device for critical care nursing shown in the figure comprises a device body 1, a drainage tube 2 is fixed on the device body 1, and a protective structure 3 is sleeved on the drainage tube 2;

[0029] The protective structure 3 includes a first anti-pressure block 31, a second anti-pressure block 32 and an elastic band 33. Two first anti-pressure blocks 31 are provided and are mirror-imaged along the cross section of the drainage tube 2. A plurality of second anti-pressure blocks 32 are provided and are evenly distributed between the two first anti-pressure blocks 31. The elastic band 33 is fixedly connected between two adjacent second anti-pressure blocks 32 or between the second anti-pressure block 32 and the first anti-pressure block 31.

[0030] The first pressure-proof block 31 includes 331, an elastic sleeve 312 and an airbag 313. The elastic sleeve 312 is fixedly embedded in the through hole in the middle of the support block 311. The elastic sleeve 312 is movably sleeved on the drainage tube 2. The airbag 313 is fixed to one end of the elastic sleeve 312. The airbag 313 is fixed to the inner wall of the support block 311.

[0031] The first anti-pressure block 31 is provided with an adjustment structure for inflating or depressurizing the airbag 313;

[0032] After the airbag 313 is filled with gas, it has an interference fit with the outer wall of the drainage tube 2. After the airbag 313 is filled with gas, the minimum inner diameter is smaller than the outer diameter of the drainage tube 2. According to the actual usage conditions and the diameter of the drainage tube 2, the interference fit and the stabilizing effect are better when the difference between the two is set to 0.5-3mm.

[0033] Based on the above structure, after the protective structure 3 is sleeved on the drainage tube 2, if a certain section of the drainage tube 2 needs to be pressure-proofed, the user (such as medical staff, patients, and patients' family members) only needs to pull the first anti-pressure blocks 31 at both ends to drive the multiple second anti-pressure blocks 32 in the middle section to move synchronously, so that the protective structure 3 moves to a predetermined position as a whole. At this time, the user only needs to inflate the airbag 313 through the adjustment structure to make the airbag 313 deform and bulge inward, so that the inner wall of the airbag 313 and the outer wall of the drainage tube 2 have an interference fit, and the friction between the airbag 313 and the drainage tube 2 can make the drainage tube 2 and the airbag 313 protrude inward. The position of the bag 313 is relatively fixed. At this time, the air bag 313 fixes the position of the first anti-pressure block 31. When the positions of the two first anti-pressure blocks 31 at both ends are fixed, the positions of the multiple second anti-pressure blocks 32 in the middle section are also limited to a certain range, so that the protective structure 3 as a whole can be fixed on a certain section of the drainage tube 2, and is not easily affected by external forces to produce movement, so that it can provide stable and effective anti-pressure protection for the section of the drainage tube 2 that needs to be protected against pressure, improve the stability of the anti-pressure protection of the drainage tube 2, and is more conducive to playing a stable and effective anti-blockage role in the use of the drainage device for critical care nursing.

[0034] Furthermore, an air inlet nozzle 316 is fixed and connected to one side of the airbag 313;

[0035] The adjustment structure includes an adjustment bolt 314 and a through hole. The other end of the air inlet nozzle 316 is connected to the through hole. The adjustment bolt 314 is screwed into the through hole. The adjustment bolt 314 is close to the air inlet nozzle 316 to form a sealing plug and form a seal with the inner wall of the through hole.

[0036] By adjusting the position of the adjusting bolt 314 in the through hole, one end of the adjusting bolt 314 squeezes the air in the through hole, so that the air in the through hole enters the airbag 313 through the air inlet nozzle 316, thereby inflating the airbag 313 to deform it and hold the drainage tube 2 tightly, thereby playing a good limiting role on the first anti-pressure block 31 (that is, the protective structure 3 as a whole).

[0037] Furthermore, the through hole is a threaded hole 3112, and the adjusting bolt 314 is provided with a threaded portion adapted to the threaded hole 3112. The screw-in adjustment of the thread can effectively prevent the adjusting bolt 314 from self-displacement in the threaded hole 3112, thereby preventing the airbag 313 from producing uncontrolled pressure relief and improving the stability of the airbag 313 after inflation.

[0038] Furthermore, the support block 311 is provided with an air cavity 3111 connected to the threaded hole 3112, a piston plate 315 slides in the air cavity 3111, and the periphery of the piston plate 315 forms a seal with the inner wall of the air cavity 3111;

[0039] One end of the adjusting bolt 314 abuts against a side of the piston plate 315 away from the air inlet nozzle 316 .

[0040] By setting the air cavity 3111 and the piston plate 315, the volume of the gas pressed into the airbag 313 can be further increased, ensuring that the airbag 313 can hold the drainage tube 2 well after deformation. At the same time, the setting of the piston plate 315 can be used in conjunction with the adjusting bolt 314 to prevent air from escaping from the gap between the adjusting bolt 314 and the threaded hole 3112. On the premise of ensuring that the position of the adjusting bolt 314 can be self-fixed, it is further ensured that the gas in the airbag 313 will not escape.

[0041] Furthermore, the end of the adjusting bolt 314 is rotatably connected to the side of the piston plate 315 away from the air inlet nozzle 316, which can reduce the friction between the end of the adjusting bolt 314 and the side of the piston plate 315, thereby reducing the wear between the piston plate 315 and the end of the adjusting bolt 314, and to a certain extent extending the service life of the adjusting bolt 314 and the piston plate 315, that is, extending the service life of the first anti-pressure block 31, ensuring a long-term and effective limiting effect.

[0042] Working principle of the utility model: in daily use, after the protective structure 3 is sleeved on the drainage tube 2, if a certain section of the drainage tube 2 needs to be pressure-proofed, the user only needs to pull the first pressure-proof blocks 31 at both ends to drive the multiple second pressure-proof blocks 32 in the middle section to move synchronously, so that the protective structure 3 moves as a whole to a predetermined position. At this time, the user only needs to inflate the airbag 313 through the adjustment structure. Specifically, rotate the adjustment bolt 314 to screw it into the threaded hole 3112. During this process, the piston plate 315 is driven by the adjustment bolt 314 to move from the end away from the air inlet nozzle 316 in the air cavity 3111 to the end close to the air inlet nozzle 316, so that the air in the air cavity 3111 is compressed and enters the airbag 313 through the air inlet nozzle 316, causing the airbag 313 to inward. The deformed bulge makes the inner wall of the airbag 313 and the outer wall of the drainage tube 2 have an interference fit, and the friction force between the airbag 313 and the drainage tube 2 can make the positions of the drainage tube 2 and the airbag 313 relatively fixed. At this time, the airbag 313 fixes the position of the first anti-pressure block 31. When the positions of the two first anti-pressure blocks 31 at both ends are fixed, the positions of the multiple second anti-pressure blocks 32 in the middle section are also limited to a certain range, so that the protective structure 3 as a whole can be fixed on a certain section of the drainage tube 2, and is not easily moved by external forces, so that it can provide stable and effective anti-pressure protection for the section of the drainage tube 2 that needs to be protected against pressure, improve the stability of the anti-pressure protection of the drainage tube 2, and is more conducive to playing a stable and effective anti-blockage role in the use of the drainage device for critical care nursing.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
