A chest tube fixing device for thoracic surgery nursing

Abstract

The present invention discloses a chest tube fixing device for thoracic surgery nursing, comprising a catheter, wherein a positioning assembly is provided on the outer peripheral side of the catheter, and the positioning assembly comprises a first adhesive pad and a second adhesive pad. When the improved chest tube is used, when the chest tube shakes, due to the constraints and limits at the two ends of the catheter, the shaking of the chest tube will not drive the chest tube to shake together, thereby avoiding secondary damage to the patient's wound. When the chest tube is caught by a foreign object, so that the chest tube is subjected to a great pulling force, as the chest tube is pulled out of the sleeve, the sealing mechanism automatically completes the blocking of the sleeve opening, thereby preventing the remaining waste liquid in the catheter from continuing to flow out of the sleeve. At the same time, the restraint and limit of the sleeve on the catheter prevents the chest tube in the patient's wound from being displaced, causing secondary damage to the patient's wound, and affecting the patient's postoperative treatment and nursing work.

Description

Technical Field

[0001] The invention relates to the technical field of chest cavity pipeline fixing devices, and in particular to a chest cavity pipeline fixing device for thoracic surgery nursing. Background Art

[0002] After a patient undergoes thoracic surgery in the hospital, a chest tube is generally inserted into the chest cavity. The chest tube is used to drain the pus, blood or other fluids accumulated in the chest cavity to the outside of the body to prevent postoperative infection and promote wound healing. Since the chest tube has a certain gravity, it is easy to exert a certain pulling effect on the patient's wound. Generally, the chest tube needs to be fixed to prevent the tube in the patient's chest cavity from shifting in position and causing secondary injury to the patient.

[0003] The existing chest tube is generally fixed by medical staff directly sticking the tube near the chest wound with medical tape. The fixing effect is poor, and the shaking of the tube caused by the contact between the external objects and the tube is easily transmitted to the tube inside the chest cavity, which may cause secondary damage to the patient's wound. When the external tube is caught by the external object, the tube is often subjected to a large pulling force, which may cause the tube to fall off and further cause secondary damage to the patient's wound, affecting the patient's postoperative treatment and nursing work.

[0014] Preferably, the push plate is located between the soft ring and the inner wall of the sleeve, and the left and right sides of the four ends of the push plate are both arranged in an arc shape.

[0015] Preferably, springs are provided between the four corners of the push plate and the inner wall of the sleeve, and one end of the spring is fixedly connected to the push plate, and the other end of the spring is in contact with the inner wall of the sleeve.

[0016] The present invention has at least the following beneficial effects:

[0017] 1. When installing the improved chest tube fixing device, the medical staff first connects the liquid inlet end of the catheter with the liquid discharge end of the chest tube in the patient's wound, and then the operator fixes the liquid inlet end of the catheter to a suitable position on the patient's chest by bonding and fixing the first adhesive pad to the patient's chest. Then, the operator fixes the tail end of the catheter to a suitable position on the patient's waist by bonding and fixing the second adhesive pad to the patient's waist and limiting the catheter discharge end by the sleeve. Finally, the operator inserts the liquid inlet end of the chest tube into the sleeve. At this time, the seal automatically forms multiple sealing barrier lines between the chest tube and the sleeve to complete the sealing of the gap between the chest tube and the inner wall of the sleeve. At the same time, after the chest tube passes through the seal, due to the push of the chest tube, the sealing mechanism automatically releases the sealing state of the sleeve. At this time, the friction between the catheter, the seal and the inner wall of the sleeve completes the connection and fixation between the catheter and the chest tube, and the catheter and the chest tube are automatically connected at the same time, and the operator does not need to perform other operations. The device is easy to install and operate;

[0018] 2. When installing the above device, if the catheter is sufficient, the operator inserts part of the chest tube into the limiting mechanism to further constrain and position the fluid inlet end of the chest tube, thereby enhancing the stability of the connection between the sleeve and the chest tube. If the catheter is too long, the operator bends the catheter and passes the bent part of the catheter through between the connecting mechanism and the limiting mechanism. Then the operator bends the chest tube and reinserts part of the chest tube into the limiting mechanism to complete the chest tube constraint and limitation. Therefore, the position of the bent catheter can be stabilized through the mutual interference between the chest tube and the catheter, so that the bent catheter will not spread out. Finally, the length of the catheter can be adjusted as needed, so that the device can adapt to the use needs of different patients, thereby enhancing the scope of application of the device.

[0019] 3. When the improved chest tube is in use, when the chest tube shakes, due to the constraints and limits at both ends of the tube, the shaking of the chest tube will not cause the chest tube to shake together, thereby avoiding secondary damage to the patient's wound. When the chest tube is caught by foreign objects, causing the chest tube to be subjected to great tension, as the chest tube is pulled out of the sleeve, the sealing mechanism automatically completes the sealing of the sleeve opening, thereby preventing the remaining waste liquid in the tube from continuing to flow out of the sleeve. At the same time, the constraint and limit of the sleeve on the catheter prevents the chest tube in the patient's wound from shifting, causing secondary damage to the patient's wound and affecting the patient's postoperative treatment and nursing work.

DETAILED DESCRIPTION

[0030] In order to make the technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] The present invention provides a technical solution: referring to Figure 1 - Figure 8 The present invention discloses a thoracic tube fixing device for thoracic surgery nursing, comprising a catheter 1, a positioning assembly 2 is provided on the outer peripheral side of the catheter 1, the positioning assembly 2 comprises a first adhesive pad 21 and a second adhesive pad 24, the first adhesive pad 21 is sleeved on the outer peripheral side of one end of the catheter 1, and a limiting mechanism 3 is provided on the right end of the top side of the second adhesive pad 24;

[0032] A connecting mechanism 22 is provided at the left end of the top side of the second adhesive pad 24. The connecting mechanism 22 includes a sleeve 221 which is I-shaped when viewed from above. The other end of the catheter 1 is inserted into an opening at one end of the sleeve 221 and is fixedly connected to the sleeve 221. A sealing member 222 is provided on the inner wall of the opening at the other end of the sleeve 221. A sealing mechanism 4 is provided in the sleeve 221.

[0033] In this embodiment, when installing the improved chest tube fixing device, the medical staff first connects the liquid inlet end of the catheter 1 to the liquid discharge end of the chest tube in the patient's wound, then the operator tears off the isolation film on the first adhesive pad 21, and fixes the liquid inlet end of the catheter 1 to a suitable position on the patient's chest through the first adhesive pad 21. Then, the operator tears off the isolation film on the second adhesive pad 24, and fixes the tail end of the catheter 1, the sleeve 221 and the limiting mechanism 3 to a suitable position on the patient's waist through the bonding of the second adhesive pad 24 to the patient's waist. Finally, the operator inserts the liquid inlet end of the chest tube into the sleeve 221. At this time, the sealing member 222 is located between the chest tube and the sleeve 221 to form a multiple sealing barrier line, thereby sealing the gap between the chest tube and the inner wall of the sleeve 221. At the same time, after the chest tube passes through the sealing member 222, due to the push of the chest tube, the sealing mechanism 4 automatically releases the sealing state of the sleeve 221. At this time, the catheter 1 and the chest tube are automatically connected. The mutual conflict between the chest tube and the inner wall of the sleeve 221 and the mutual conflict between the sealing member 222 and the outer wall of the chest tube can generate a large friction force between the chest tube and the sleeve 221, so that the liquid inlet end of the chest tube is stably inserted into the sleeve 221.

[0034] When installing the device, if the catheter 1 is sufficient, the operator inserts part of the chest tube into the limiting mechanism to further constrain and position the fluid inlet end of the chest tube, thereby enhancing the stability of the connection between the sleeve 221 and the chest tube. If the catheter 1 is too long, the operator bends the catheter 1 and passes part of the bent catheter 1 between the connecting mechanism 22 and the limiting mechanism 3. Then the operator bends the chest tube and re-inserts part of the chest tube into the limiting mechanism 3 to complete the chest tube constraint and positioning. Thus, the position of the bent catheter 1 can be stabilized by the mutual interference between the chest tube and the catheter 1, so that the bent catheter 1 will not spread out. Finally, the length of the catheter 1 can be adjusted as needed, so that the device can adapt to the use requirements of different patients, thereby enhancing the scope of application of the device.

[0035] When the improved chest tube is used, when the chest tube shakes, due to the constraints and limits at two positions of the catheter 1, the shaking of the chest tube will not cause the chest tube to shake together, thereby avoiding secondary damage to the patient's wound. When the chest tube is caught by foreign objects, causing the chest tube to be subjected to great tension, as the chest tube is pulled out of the sleeve 221, the sealing mechanism automatically completes the blocking of the opening of the sleeve 221, thereby preventing the remaining waste liquid in the catheter 1 from continuing to flow out of the sleeve 221. At the same time, the sleeve 221 cooperates with the constraints and limits on the catheter 1 to prevent the chest tube in the patient's wound from being shifted, causing secondary damage to the patient's wound and affecting the patient's postoperative treatment and nursing work.

[0036] It should be noted that the above-mentioned catheter 1 is a transparent tube.

[0037] In a further preferred embodiment of the present invention, Figure 3 and Figure 4 As shown, the first soft block 23 is fixedly mounted on the left end of the top side of the second adhesive pad 24, and the sleeve 221 is fixedly mounted in the mounting hole of the first soft block 23, and both ends of the sleeve 221 are arranged in an arc shape;

[0038] In this embodiment, after the operator fixes the second adhesive pad 24 on the patient's waist, the first soft block 23 wraps around the sleeve 221, so the operator will not come into contact with the harder sleeve 221 and cause the patient to feel uncomfortable.

[0039] In a further preferred embodiment of the present invention, Figure 4 and Figure 5 As shown, the sealing member 222 includes a plurality of soft rings 2222, and a plurality of annular grooves 2221 are formed on the inner wall of the opening at the other end of the sleeve 221, and the spacing between two adjacent annular grooves 2221 is equal, and the soft rings 2222 are arranged in the corresponding annular grooves 2221, and the inner ring wall of the soft ring 2222 extends to the outside of the corresponding annular groove 2221;

[0040] In the present embodiment, during the process in which the operator inserts the fluid inlet end of the chest tube into the sleeve 221, due to the mutual interference between the chest tube and the soft ring 2222, the soft ring 2222 can be squeezed and pushed along the outer ring wall of the soft ring 2222, so that the soft ring 2222 shrinks and deforms and retracts into the annular groove 2221, so that the fluid inlet end of the chest tube can directly pass through the soft ring 2222 without the operator performing other operations, thereby facilitating the connection and assembly between the catheter 1 and the chest tube.

[0041] In a further preferred embodiment of the present invention, Figure 5 As shown, the cross-section of the soft ring 2222 is annular in shape, and the soft ring 2222 is filled with air, and the outer peripheral wall of the soft ring 2222 is in contact with the inner wall of the opening of the corresponding annular groove 2221;

[0042] In this embodiment, as the chest tube moves, after the chest tube passes through all the soft rings 2222, the outer wall of the soft ring 2222 is tightly fitted with the outer peripheral wall of the chest tube due to the push of the internal gas of the soft ring 2222 on the tube wall of the soft ring 2222, thereby generating a friction between the chest tube and the sleeve 221, which is used to constrain the position between the chest tube and the sleeve 221, and a plurality of soft rings 2222 are tightly fitted with the chest tube, so that multiple waterproof barrier lines can be formed between the chest tube and the sleeve 221 to prevent waste liquid from flowing out from the gap between the sleeve 221 and the chest tube;

[0043] It should be noted that the gas filled in the soft ring 2222 tube is a suitable high-pressure gas.

[0044] In a further preferred embodiment of the present invention, Figure 2 As shown, the first adhesive pad 21 is composed of two rectangular stickers 211 and a plurality of sticker strips 212. Both ends of the plurality of sticker strips 212 are fixedly connected to the two rectangular stickers 211, respectively, and the intervals between two adjacent sticker strips 212 are equal. The sticker strips 212 are fixedly connected to the outer peripheral wall of the catheter 1 through an adhesive.

[0045] In this embodiment, when the operator fixes the liquid inlet end of the catheter 1, the operator tears off the isolation film on the first adhesive pad 21, and adheres and fixes the strip 212 to the catheter 1, and then adheres and fixes the rectangular sticker 211 to a suitable position on the patient's chest after the strip 212 is straightened. The strip 212 has a small shielding area on the catheter 1, and the operator's line of sight can easily observe the situation inside the catheter 1, avoiding the blocking position of the catheter 1. The operator cannot observe in time and affect the use of the device;

[0046] It should be noted that an isolation film is commonly provided on the bottom sides of the two rectangular stickers 211 and the plurality of sticker strips 212 .

[0047] In a further preferred embodiment of the present invention, Figure 1 and Figure 3 As shown, the limiting mechanism 3 includes an elastic tube 31 with a cross-sectional shape of three-quarters of a ring, a second soft block 32 is fixedly mounted on the right end of the top side of the second adhesive pad 24, and the bottom of the elastic tube 31 is inserted into the mounting groove of the second soft block 32 and fixedly connected to the second soft block 32;

[0048] In this embodiment, after the liquid inlet end of the chest tube is inserted into the sleeve 221, the operator inserts part of the chest tube from the break of the elastic tube 31 into the elastic tube 31 through the deformation of the wall of the elastic tube 31. At this time, due to the mutual interference between the chest tube and the inner wall of the elastic tube 31, a large friction force can be generated between the chest tube and the elastic tube 31, thereby applying a restraining force to the liquid inlet end of the chest tube to enhance the stability of the connection between the chest tube and the sleeve 221.

[0049] In a further preferred embodiment of the present invention, Figure 1 and Figure 8 As shown, a plurality of elastic strips 33 in the shape of a three-quarter ring are fixedly mounted on the inner wall of the elastic tube 31, and the spacing between two adjacent elastic strips 33 is equal, and the cross-section of the elastic strip 33 is in the shape of a triangle;

[0050] In this embodiment, after the chest tube is pressed into the elastic tube 31, the elastic tube 31 pushes and presses the elastic strip 33, so that the tapered end of the elastic strip 33 and the outer annular wall of the chest tube are in conflict with each other, thereby causing a corresponding deformation of a part of the chest tube. The friction between the catheter 1 and the elastic tube 31 is greatly enhanced through the mutual conflict between the limit strip and the chest tube, thereby enhancing the stability of the constraint and limit between the chest tube and the elastic tube 31.

[0051] In a further preferred embodiment of the present invention, Figure 4 , Figure 6 and Figure 7 As shown, the blocking mechanism 4 includes a sealing plate 41, which is arranged in the opening at one end of the sleeve 221, and the outer ring wall of the sealing plate 41 is arranged in an arc shape and contacts the inner wall of the middle part of the sleeve 221, the outer diameter of the sealing plate 41 is smaller than the inner diameter of the catheter 1, and a push plate 42 in a cross shape is arranged in the opening at the other end of the sleeve 221, and the four ends of the push plate 42 are in contact with the inner wall of the sleeve 221, and two connecting blocks 43 are arranged opposite to each other between the push plate 42 and the sealing plate 41, and the two ends of each connecting block 43 are fixedly connected to the sealing plate 41 and the push plate 42 respectively by adhesive;

[0052] In this embodiment, after the fluid inlet end of the chest tube passes through the soft ring 2222, as the chest tube continues to move, when the fluid inlet end of the chest tube moves to the position of the push plate 42, due to the mutual interference between the chest tube and the push plate 42, the sealing plate 41 can be pushed away from the inner wall of the sleeve 221 through the connecting block 43 until the spring 44 is compressed to the limit. At this time, the sealing plate 41 is separated from the inner wall of the sleeve 221, and the blocking state between the sleeve 221 and the chest tube is directly released. At this time, the inside of the catheter 1, the inside of the sleeve 221 and the inside of the chest tube are automatically connected.

[0053] In a further preferred embodiment of the present invention, Figure 6 and Figure 7 As shown, the push plate 42 is located between the soft ring 2222 and the inner wall of the sleeve 221, and the left and right sides of the four ends of the push plate 42 are both arranged in an arc shape;

[0054] In this embodiment, the arc surface setting of the push plate 42 can avoid the sharp end of the push plate 42 from conflicting with the soft ring 2222, which would cause damage to the soft ring 2222. In addition, during the assembly process between the push plate 42 and the sleeve 221, when the operator inserts the push plate 42 into the sleeve 221, due to the mutual conflict between the arc surface at the end of the push plate 42 and the soft ring 2222, part of the soft ring 2222 can be pressed into the annular groove 2221 along the arc surface of the soft ring 2222. The installation operation of the push plate 42 will not be affected by whether the soft ring 2222 is installed in the annular groove 2221, thereby facilitating the assembly of the device.

[0055] In a further preferred embodiment of the present invention, Figure 6 and Figure 7 As shown, springs 44 are provided between the four corners of the push plate 42 and the inner wall of the sleeve 221, and one end of the spring 44 is fixedly connected to the push plate 42, and the other end of the spring 44 is in contact with the inner wall of the sleeve 221;

[0056] In this embodiment, when the chest tube slides out of the sleeve 221, the spring 44 quickly pushes the push plate 42 to return to its original position, and then pulls the sealing plate 41 through the connecting block 43 to fit tightly with the inner wall of the middle part of the sleeve 221, automatically completing the sealing of the opening of the sleeve 221, thereby preventing a large amount of waste liquid from flowing out of the catheter 1 and causing environmental pollution.

[0057] Working principle: When installing the improved chest tube fixing device, the medical staff first connects the liquid inlet end of the catheter 1 to the liquid discharge end of the chest tube in the patient's wound, then the operator tears off the isolation film on the first adhesive pad 21, and glues the adhesive strip 212 to the catheter 1, and then glues the rectangular sticker 211 to a suitable position on the patient's chest after the adhesive strip 212 is straightened;

[0058] After the end of the catheter 1 is fixed, the operator tears off the isolation film on the second adhesive pad 24, and fixes the first soft block 23 and the second soft block 32 at a suitable position on the patient's waist by bonding the second adhesive pad 24 to the patient's waist. Then, the operator passes the fluid inlet end of the chest tube through the elastic tube 31 and inserts the fluid inlet end of the chest tube into the sleeve 221.

[0059] After the chest tube passes through the elastic tube 31, the outer wall of the chest tube is closely attached to the inner wall of the elastic tube 31, thereby generating a friction to constrain the position between the chest tube and the elastic tube 31. At the same time, due to the push and press of the elastic strip 33 by the elastic tube 31, the tapered end of the elastic strip 33 and the outer ring wall of the chest tube are mutually in conflict, thereby causing a corresponding deformation of a part of the chest tube. Thus, the friction between the catheter 1 and the elastic tube 31 is greatly enhanced through the mutual conflict between the limiting strip and the chest tube, thereby enhancing the stability of the constraint and limit between the chest tube and the elastic tube 31.

[0060] During the process of inserting the liquid inlet end of the above-mentioned chest tube into the sleeve 221, due to the mutual interference between the chest tube and the soft ring 2222, the soft ring 2222 can be squeezed and pushed along the outer ring wall of the soft ring 2222, so that the soft ring 2222 shrinks and deforms and shrinks into the annular groove 2221, so that the liquid inlet end of the chest tube can directly pass through the soft ring 2222, and after the chest tube passes through all the soft rings 2222, due to the push of the tube wall of the soft ring 2222 by the internal gas of the soft ring 2222, the outer wall of the soft ring 2222 and the outer peripheral wall of the chest tube are closely fitted, thereby generating a friction between the chest tube and the sleeve 221, which is used to constrain the position between the chest tube and the sleeve 221, and a plurality of soft rings 2222 are closely fitted with the chest tube, and multiple waterproof barrier lines can be formed between the chest tube and the sleeve 221 to prevent waste liquid from flowing out from the gap between the sleeve 221 and the chest tube;

[0061] After the chest tube passes through the soft ring 2222, the liquid inlet end of the chest tube continues to move toward the sealing plate 41, and when the liquid inlet end of the chest tube moves to the position of the push plate 42, due to the mutual interference between the chest tube and the push plate 42, the sealing plate 41 can be pushed away from the inner wall of the sleeve 221 through the connecting block 43 until the spring 44 is compressed to the limit, and then the sealing plate 41 is separated from the inner wall of the sleeve 221, and the blocking state between the sleeve 221 and the chest tube is directly released. At this time, the inside of the catheter 1, the inside of the sleeve 221 and the inside of the chest tube are automatically connected;

[0062] It should be noted that after the spring 44 is compressed, the friction between the chest tube and the sleeve 221 can offset the thrust of the spring 44 on the push plate 42, so that the spring 44 maintains a compressed state. At the same time, the friction between the chest tube and the elastic tube 31 can exert a restraining force on the liquid inlet end of the chest tube, so that the liquid inlet end of the chest tube can be stably inserted into the sleeve 221.

[0063] When the improved chest tube fixing device is in use, when the chest tube shakes, due to the constraints and limits at two positions of the catheter 1, the shaking of the chest tube will not cause the chest tube to shake together. When the chest tube is caught by foreign objects, causing the chest tube to be subjected to great tension, as the chest tube is pulled out of the sleeve 221, the spring 44 quickly pushes the push plate 42 to reset and move, and then pulls the sealing plate 41 to fit tightly with the inner wall of the middle part of the sleeve 221 through the connecting block 43, automatically completing the blocking of the opening of the sleeve 221, so that the remaining waste liquid in the catheter 1 will not continue to flow out of the sleeve 221;

[0064] In the process of installing the catheter 1, if the catheter 1 is too long, the operator can pull the chest tube out of the elastic tube 31 by deforming the wall of the elastic tube 31, and then bend the catheter 1 to pass through the first soft block 23 and the second soft block 32 to adjust the length of the catheter 1. Then, the operator bends the chest tube and reinserts part of the chest tube into the elastic tube 31, and then restrains part of the catheter 1 between the first soft block 23 and the second soft block 32 through the mutual interference between the chest tube and the catheter 1, so that the device can meet the use needs of different patients;

[0065] During the production of the device, when assembling the sleeve 221 and the soft ring 2222, the operator can directly press the soft ring 2222 into the annular groove 2221 through the contraction deformation of the soft ring 2222. At this time, due to the mutual interference between the soft ring 2222 and the inner wall of the opening of the annular groove 2221, part of the soft ring 2222 can be constrained and limited in the annular groove 2221;

[0066] When assembling the sleeve 221, the sealing plate 41 and the push plate 42, the operator first fixes the connection block 43 on one side of the push plate 42 by means of adhesive, and then inserts the sealing plate 41 into the sleeve 221 from one end of the sleeve 221 until the sealing plate 41 and the inner wall of the sleeve 221 are in contact with each other, and then inserts the sealing plate 41 into the sleeve 221 from the other end of the sleeve 221 until the connection block 43 and the sealing plate 41 are in contact with each other, and then the connection between the connection block 43 and the sealing plate 41 can be completed by means of adhesive, and the device assembly operation is simple;

[0067] It should be noted that, in the process of inserting the push plate 42 into the sleeve 221, due to the mutual interference between the arc surface at the end of the push plate 42 and the soft ring 2222, part of the soft ring 2222 can be pressed into the annular groove 2221 along the arc surface of the soft ring 2222, and the installation operation of the push plate 42 will not be affected by whether the soft ring 2222 is installed in the annular groove 2221.
