Abstract
Description
Technical Field
[0001] This disclosure relates to the field of medical device technology, and in particular to a device for fixing an internal jugular vein catheter. Background Technology
[0002] Extracorporeal membrane oxygenation (ECMO) is a technology used for continuous extracorporeal life support, primarily to provide continuous extracorporeal respiration and circulation for patients with severe cardiopulmonary failure, thus sustaining their lives. In venous-venous extracorporeal membrane oxygenation (VV-ECMO), venous blood is drawn through a vein, oxygenated by a membrane lung to remove carbon dioxide, and then pumped into another vein, typically the internal jugular vein. If the catheter used to pump venous blood becomes displaced or dislodged, it can be life-threatening; therefore, it is essential to secure the internal jugular vein catheter.
[0003] In related techniques, the internal jugular vein catheter is usually fixed to the patient's head using adhesive tape or sutures, with the internal jugular vein catheter close to the patient's ear.
[0004] However, adhesive tape or sutures used for fixation are prone to loosening due to neck movement and skin oils, resulting in insecure fixation of the internal jugular vein catheter. Furthermore, because the internal jugular vein catheter is heavy and typically remains in place for extended periods, overly tight adhesive tape or sutures can cause pressure sores on the patient's ear. Utility Model Content
[0005] This disclosure provides a device for fixing the internal jugular vein catheter, which improves the stability of the internal jugular vein catheter fixation and reduces the risk of pressure sores in the patient's ear. The technical solution includes at least the following:
[0006] On one hand, an internal jugular vein catheter fixation device is provided, including a head fixation strap and a catheter fixation structure. The head fixation strap includes an annular fixation strap and an occipital fixation strap. The annular fixation strap is used to fix the top of the head and the chin and wraps around the face. The occipital fixation strap is connected to and intersects with the annular fixation strap. Two ear protectors are provided on the occipital fixation strap to distribute pressure on the ears. The catheter fixation structure is disposed on the head fixation strap.
[0007] Optionally, the ear shield is equipped with a pressure sensor alarm, which is used to issue an alarm signal when the pressure between the ear shield and the ear is greater than or equal to a pressure threshold.
[0008] Optionally, the ear protector is further provided with a tension detection alarm module, which is used to issue an alarm signal when the skin tension is less than or equal to a tension threshold.
[0009] Optionally, the internal jugular vein catheter fixation device further includes a displacement sensor alarm, which is disposed within the catheter fixation structure and is used to issue an alarm signal when the relative displacement between the catheter fixation structure and the internal jugular vein catheter is greater than or equal to a distance threshold.
[0010] Optionally, the resolution of the displacement sensor alarm is 0.05 mm to 0.15 mm.
[0011] Optionally, the occipital fixation strap includes a first fixation strap and a second fixation strap. The two ends of the first fixation strap are respectively connected to the ear via the annular fixation strap. Each end of the first fixation strap has an ear placement opening, and each ear protector is correspondingly positioned at one of the ear placement openings. One end of the second fixation strap is connected to the middle of the first fixation strap, and the other end of the second fixation strap is connected to the top of the head via the annular fixation strap. The catheter fixation structure is located on the outer side of the annular fixation strap and on the side of the ear away from the occipital region.
[0012] Optionally, the annular fixing band includes a first part and a second part, the first part and the second part are connected to the top of the head by a first adhesive structure and to the chin by a second adhesive structure; the second fixing band is connected to the first part or the second part to the top of the head by a third adhesive structure.
[0013] Optionally, the occipital fixation strap is used to fix the occipital region and the forehead and surrounds the occipital region of the forehead; the ear protector is disposed at the intersection of the occipital fixation strap and the annular fixation strap, and is located on the side of the occipital fixation strap away from the top of the head and the side of the annular fixation strap close to the occipital region; the conduit fixing structure is disposed on the outer side of the occipital fixation strap and is located on the side of the ear away from the occipital region.
[0014] Optionally, the occipital fixation strap includes a third fixation strap and a fourth fixation strap. The third fixation strap is used to fix the occipital region, and the fourth fixation strap is used to fix the forehead region. Both ends of the fourth fixation strap are provided with a locking structure. The catheter fixation structure is a fourth adhesive structure. The two ends of the third fixation strap pass through the two locking structures respectively and are then connected to the fourth fixation strap on both sides of the forehead region through the fourth adhesive structure.
[0015] Optionally, the surface of the head strap is provided with an antibacterial coating.
[0016] The beneficial effects of the technical solutions provided in this disclosure include at least the following:
[0017] In this embodiment, the head fixation strap is configured as a circular fixation strap and an occipital fixation strap. The circular fixation strap is used to fix the top of the head and the chin, and wraps around the face. The occipital fixation strap is connected to and intersects with the circular fixation strap. The head fixation strap can simultaneously limit and fix the top of the patient's head, chin, and occipital region, thereby reducing the chance of the head fixation strap loosening. Setting the catheter fixation structure on the head fixation strap can effectively reduce the chance of internal jugular vein catheter displacement or dislodgement, improving the stability of the internal jugular vein catheter fixation. Furthermore, two ear protectors are provided on the occipital fixation strap. The ear protectors can distribute pressure on the ears, reducing the pressure on the ears caused by the head fixation strap or internal jugular vein catheter, thereby reducing the risk of pressure sores on the ears.

[0026] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.
[0027] Example 1:
[0028] Figure 1 This is a schematic diagram of the structure of an internal jugular vein catheter fixation device provided in an embodiment of this disclosure. Figure 2 This is a schematic diagram illustrating the wearing of an internal jugular vein catheter fixation device according to an embodiment of this disclosure. See also... Figure 1 and Figure 2 The internal jugular vein catheter fixation device includes a head fixation strap 1 and a catheter fixation structure 2. The head fixation strap 1 includes a circular fixation strap 10 and an occipital fixation strap 20. The circular fixation strap 10 is used to fix the top of the head and jaw and wraps around the face. The occipital fixation strap 20 is connected to and intersects with the circular fixation strap 10. Two ear protectors 30 are provided on the occipital fixation strap 20 to distribute pressure on the ears. The catheter fixation structure 2 is disposed on the head fixation strap 1.
[0029] In this embodiment, the head fixation strap 1 is configured as a ring-shaped fixation strap 10 and an occipital fixation strap 20. The ring-shaped fixation strap 10 is used to fix the top of the head and the chin and wraps around the face. The occipital fixation strap 20 is connected to and intersects with the ring-shaped fixation strap 10. The head fixation strap 1 can simultaneously limit and fix the top of the patient's head, chin, and occipital region, thereby reducing the probability of the head fixation strap 1 loosening. The catheter fixation structure 2 is set on the head fixation strap 1, which can effectively reduce the probability of displacement or dislodgement of the internal jugular vein catheter 3 and improve the fixation firmness of the internal jugular vein catheter 3. Furthermore, two ear protectors 30 are provided on the occipital fixation strap 20. The ear protectors 30 can distribute the pressure on the ears and reduce the pressure on the ears caused by the head fixation strap 1 or the internal jugular vein catheter 3, thereby reducing the risk of pressure sores on the ears.
[0030] For example, the shape of the ear shield 30 may be similar to the shape of the ear, and the size of the ear shield 30 may be slightly larger than the size of the ear.
[0031] Optionally, the ear shield 30 may be made of a shape memory alloy. Shape memory alloys are highly elastic, which can more effectively distribute pressure on the ear and ensure better comfort for the patient.
[0032] For example, the ear shield 30 can be a shield containing a shape memory alloy skeleton.
[0033] For example, the shape memory alloy can be a nickel-titanium based alloy. Nickel-titanium based alloys can recover a preset shape at body temperature and can withstand repeated deformation without plastic damage. Thus, the ear protector 30 can effectively protect the patient's ear. For instance, when the patient is lying on their side and their ear and ear protector 30 are subjected to external pressure, the ear protector 30 can deform to cushion the pressure on the ear and distribute the pressure. When the patient returns to a supine position, the pressure on the ear and ear protector 30 disappears, and the ear protector 30 can recover its preset shape at body temperature, thereby protecting the ear.
[0034] Optionally, the ear shield 30 is equipped with a pressure sensor alarm, which is used to issue an alarm signal when the pressure between the ear shield 30 and the ear is greater than or equal to a pressure threshold. The pressure sensor alarm can issue an alarm signal to alert the patient when the ear shield 30 exerts excessive pressure on the patient's ear, thereby effectively reducing the risk of pressure sores on the ear due to excessive pressure from the ear shield 30.
[0035] For example, the pressure sensor alarm can be a micro-electro-mechanical system (MEMS) pressure sensor alarm. For instance, the model of the pressure sensor alarm could be FSR402. In other embodiments, other models of pressure sensor alarms may be used as needed, and this disclosure does not limit this.
[0036] For example, the pressure threshold can be preset.
[0037] Optionally, the ear protector 30 is also equipped with a tension detection alarm module, which is used to issue an alarm signal when the skin tension is less than or equal to the tension threshold. The skin tension reflects the tightness of the head fixation strap 1. The tighter the head fixation strap 1 is, the greater the skin tension; the looser the fixation, the lower the skin tension. The tension detection alarm module can monitor the skin tension at the patient's ear in real time and issue an alarm when the skin tension at the ear is too low, thereby reducing the probability of displacement or dislodgement of the internal jugular vein fixation catheter 3 due to the head fixation strap 1 being too loose, and ensuring better reliability of the internal jugular vein fixation device.
[0038] For example, the tension detection alarm module can be of model JH-2. In other embodiments, the tension detection alarm module may also use other models as needed, and this disclosure does not limit this.
[0039] For example, the tension detection range of the tension detection alarm module is 0N to 15N.
[0040] For example, the tension threshold can be preset.
[0041] Optionally, the internal jugular vein catheter fixation device also includes a displacement sensor alarm, which is installed within the catheter fixation structure 2. The displacement sensor alarm is used to issue an alarm signal when the relative displacement between the catheter fixation structure 2 and the internal jugular vein catheter 3 is greater than or equal to a distance threshold. By installing a displacement sensor alarm within the catheter fixation structure 2, an alarm signal can be issued to alert the patient when the relative displacement between the catheter fixation structure 2 and the internal jugular vein catheter 3 is too large. This provides effective early warning of displacement or dislodgement of the venous fixation catheter 3, thus helping to ensure the patient's safety.
[0042] For example, the displacement sensor alarm can be of model HG-C1050. In other embodiments, other models of displacement sensor alarms may be used as needed, and this disclosure does not limit this.
[0043] Optionally, the resolution of the displacement sensor alarm is between 0.05 mm and 0.15 mm. A resolution within this range ensures high accuracy and sensitivity of the displacement sensor, further protecting the patient's safety.
[0044] For example, the resolution of the displacement sensor alarm can be 0.05mm, 0.1mm or 0.15mm, etc.
[0045] For example, the distance threshold can be preset.
[0046] Optionally, the head fixation strap 1 may be made of an elastic material. Elastic materials can improve patient comfort while ensuring good fixation.
[0047] For example, the head restraint strap 1 is made of medical-grade silicone.
[0048] Optionally, the thickness of the head strap 1 is 0.5 mm to 1.2 mm.
[0049] For example, the thickness of the head strap 1 can be 0.5mm, 0.8mm or 1.2mm, etc.
[0050] For example, the surface of the head fixation strap 1 is provided with an antibacterial coating. The antibacterial coating can effectively inhibit the proliferation of various bacteria, viruses and other microorganisms, reducing the risk of infection when patients wear the internal jugular vein catheter fixation device for a long time.
[0051] See Figure 1 and Figure 2 The occipital fixation strap 20 includes a first fixation strap 21 and a second fixation strap 22. Both ends of the first fixation strap 21 are connected to the ear via an annular fixation strap 10, and each end of the first fixation strap 21 has an ear placement opening 211, with each ear protector 30 corresponding to one ear placement opening 211. One end of the second fixation strap 22 is connected to the middle of the first fixation strap 21, and the other end of the second fixation strap 22 is connected to the top of the head via the annular fixation strap 10. The catheter fixation structure 2 is located on the outer side of the annular fixation strap 10, on the side of the ear away from the occipital region. This design ensures the head fixation strap 1 remains lightweight and has a small contact area with the patient's skin while effectively securing the top of the head, jaw, occipital region, and ear, thus reducing the likelihood of the head fixation strap 1 loosening.
[0052] For example, the annular fixation strap 10 includes a first portion 11 and a second portion 12. The first portion 11 and the second portion 12 are connected to the top of the head via a first adhesive structure 40 and to the chin via a second adhesive structure 41. The second fixation strap 22 is connected to either the first portion 11 or the second portion 12 at the top of the head via a third adhesive structure 42. In this way, the open structure of the head fixation strap 1 allows for adjustment of the size of the annular fixation strap 10 and the second fixation strap 22, enabling the head fixation strap 1 to better match the patient's head circumference and face size, thereby further improving the stability of the head fixation strap 1 and also enhancing the convenience of dynamic size adjustment.
[0053] Optionally, the first adhesive structure 40, the second adhesive structure 41, and the third adhesive structure 42 can be hook and loop fasteners. For example, a self-adhesive hook structure can be provided at one end of the connection between the first part 11 and the second part 12, and a self-adhesive fabric layer can be provided at the other end for bonding. When the second fixing strap 22 is connected to the first part 11 through the third adhesive structure 42, a self-adhesive hook structure can be provided at one end of the connection between the second fixing strap 22 and the first part 11, and a self-adhesive fabric layer can be provided at the other end for bonding; when the second fixing strap 22 is connected to the second part 12 through the third adhesive structure 42, a self-adhesive hook structure can be provided at one end of the connection between the second fixing strap 22 and the second part 12, and a self-adhesive fabric layer can be provided at the other end for bonding.
[0054] In other embodiments, the first adhesive structure 40, the second adhesive structure 41, and the third adhesive structure 42 may also be detachable tape, etc., and this disclosure does not limit them.
[0055] In one possible implementation, the head restraint 1 is made of an elastic material, and the first restraint 21, the second restraint 22, and the annular restraint 10 can also be an integral structure.
[0056] Exemplarily, the catheter fixation structure 2 and the annular fixation band 10 are connected by an adhesive structure. For example, the catheter fixation structure 2 and the annular fixation band 10 can be connected by a Velcro adhesive structure, with a self-adhesive hook structure provided on one of the catheter fixation structure 2 and the annular fixation band 10, and a self-adhesive fabric layer provided on the other for adhesive connection. The internal jugular vein catheter 3 can be fixed between the catheter fixation structure 2 and the annular fixation band 10.
[0057] In other embodiments, the catheter fixation structure 2 and the annular fixation band 10 may also be fixedly connected by sutures, etc., and this disclosure does not limit this.
[0058] like Figure 1 and Figure 2As shown, the internal jugular vein catheter fixation device includes two catheter fixation structures 2, both of which are located on the outer side of the annular fixation band 10 and on the side of the ear away from the occipital region.
[0059] In other embodiments, more or fewer catheter fixation structures 2 may be provided, as long as the internal jugular vein catheter 3 can be fixed and limited on the head fixation strap 1 during VV-ECMO treatment. This disclosure does not limit this.
[0060] Example 2:
[0061] Figure 3 This is a schematic diagram of another internal jugular vein catheter fixation device provided in an embodiment of this disclosure. Figure 4 This is a schematic diagram of wearing another internal jugular vein catheter fixation device provided in this embodiment. Embodiment Two uses the same configuration for the pressure sensor alarm, tension detection alarm module, and displacement sensor alarm as Embodiment One, and the head fixation strap is made of the same material and has the same thickness. The main difference between Embodiment Two and Embodiment One lies in the structure of the head fixation strap and the placement of the ear protector and catheter fixation structure. See also... Figure 3 and Figure 4 The occipital fixation strap 20 is used to fix the occipital region and forehead, and surrounds the forehead-top-occipital region. The ear protector 30 is located at the intersection of the occipital fixation strap 20 and the annular fixation strap 10, and is located on the side of the occipital fixation strap 20 away from the top of the head and the side of the annular fixation strap 10 close to the occipital region. The catheter fixation structure 2 is located on the outer side of the occipital fixation strap 20 and is located on the side of the ear away from the occipital region. The head fixation strap 1 can provide 360° fixation to the top of the patient's head, jaw, occipital region, and forehead, thereby effectively reducing the chance of the head fixation strap 1 loosening.
[0062] For example, the occipital fixation strap 20 includes a third fixation strap 23 and a fourth fixation strap 24. The third fixation strap 23 is used to fix the occipital region, and the fourth fixation strap 24 is used to fix the forehead. Both ends of the fourth fixation strap 24 are provided with locking structures 241. The catheter fixation structure 2 is a fourth adhesive structure 43. The two ends of the third fixation strap 23 pass through the two locking structures 241 respectively and are connected to the fourth fixation strap 24 on both sides of the forehead through the fourth adhesive structure 43. In this way, the open structure of the occipital fixation strap 20 allows for adjustment of the size of the third fixation strap 23 and the fourth fixation strap 24, so that the occipital fixation strap 20 can better match the patient's head circumference, thereby improving the fixation firmness of the head fixation strap 1 and the convenience of dynamic size adjustment of the head fixation strap 1. Furthermore, the fourth adhesive structure 43 can also be used as the catheter fixation structure 2 to fix the internal jugular vein catheter 3.
[0063] Optionally, the fourth adhesive structure 43 can be a hook and loop fastener structure. For example, a self-adhesive hook structure can be provided at one end of the connection between the third fastening strap 23 and the fourth fastening strap 24, or a self-adhesive fabric layer can be used for the adhesive connection. Figure 3 and Figure 4 In the design, at the connection between the third fixation strap 23 and the fourth fixation strap 24, the two ends of the third fixation strap 23 are narrowed and equipped with self-adhesive hook structures, and the outer surface of the fourth fixation strap 24 is provided with a self-adhesive fabric layer. The internal jugular vein catheter 3 can be fixed between the self-adhesive hooks and the self-adhesive fabric layer.
[0064] In other embodiments, the fourth adhesive structure 43 may also be a detachable tape or the like, and this disclosure does not limit it.
[0065] like Figure 3 and Figure 4 As shown, the internal jugular vein catheter fixation device includes two catheter fixation structures 2, both of which are located on the outer side of the occipital fixation band 20 and on the side of the ear away from the occipital region.
[0066] Figures 1 to 4 In this design, when the first adhesive structure 40, the second adhesive structure 41, the third adhesive structure 42, and the fourth adhesive structure 43 are hook and loop fasteners, a gradient adhesive design can be adopted, where the adhesiveness of the hook and loop fasteners gradually increases from the edge region to the center region. For example, the pressure in the edge region of the hook and loop fastener can be less than 1 N / cm². 2 The pressure in the central area of the Velcro adhesive structure can be greater than 3 N / cm. 2 .
[0067] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
