Description

Technical Field

[0001] This application relates to the technical field of medical assistive devices, and in particular to a hand restraint device based on the principle of clustering to prevent accidental removal of tubes. Background Technology

[0002] In the medical field, extubation prevention is a crucial nursing measure. Its core purpose is to prevent patients from removing various catheters, such as endotracheal tubes, intravenous catheters, drainage tubes, and gastric tubes, when they are unconscious, agitated, delirious, or uncooperative with treatment. These catheters play a vital role in the patient's treatment, monitoring, and rehabilitation. Accidental removal can lead to worsening of the condition, treatment interruption, infection, and even death. Therefore, extubation prevention is of paramount importance for ensuring patient safety and treatment effectiveness. Hand restraint devices limit the range of motion of the patient's hands, preventing them from touching and removing these catheters. Common forms include restraint gloves and restraint straps. Their design must ensure effective restraint while minimizing impact on the patient's hand blood circulation and comfort, making them suitable for agitated patients, patients with impaired consciousness, and children—groups prone to extubation.

[0003] However, existing hand restraint devices for preventing accidental extubation have certain drawbacks in practical applications, especially when finger-prick blood sampling is required. Finger-prick blood sampling is a commonly used blood collection method in clinical practice, widely used in scenarios such as blood glucose monitoring, routine blood tests, and rapid biochemical indicator detection, and has the advantages of simple operation and rapid result acquisition. However, existing hand restraint devices are often designed to comprehensively restrain the patient's hand. In order to achieve a stable effect in preventing accidental extubation, their structure usually wraps or fixes the patient's fingers, making the fingertips obstructed or difficult to reach.

[0004] This design prevents healthcare professionals from readily drawing blood from patients' fingertips. When blood is needed, they often have to first remove the restraint device, then re-secure it after the blood is drawn. This process not only increases the workload and procedures for healthcare professionals and prolongs preparation time, but in emergencies, it can even delay diagnosis and treatment. Furthermore, frequent removal and re-securement of the restraint device can compromise its stability, potentially leading to the risk of patients pulling out the catheter. In addition, for patients requiring frequent blood draws, repeated removal and reassembly of the restraint device can increase hand discomfort and may even cause accidental movement during the procedure, resulting in failed blood draws and additional pain. Summary of the Invention

[0005] The present application aims to solve one of the technical problems in the related art at least to a certain extent.

[0006] Therefore, one objective of this application is to propose a hand restraint device based on the principle of clustering to prevent accidental extubation. This device allows medical staff to perform finger-prick blood sampling without removing the restraint device, significantly reducing operational steps and workload, shortening blood sampling preparation time, and avoiding delays in emergency situations. Simultaneously, it maintains the stability of the restraint device, reducing the risk of patients accidentally extubating and ensuring treatment safety. For patients requiring frequent blood sampling, it reduces hand discomfort caused by repeated disassembly and reassembly, lowers the probability of blood sampling failure, and alleviates patient suffering.

[0007] To achieve the above objectives, a first aspect of this application proposes a hand restraint device based on the principle of clustering to prevent accidental tube removal. The device includes a receiving sleeve, two elastic bands, a covering surface, a collar assembly, an airbag assembly, two first Velcro surfaces, and an extension sleeve. A zipper is provided between the edges of the receiving sleeve and the covering surface, forming a receptacle between them. The receiving sleeve has two slots. A through hole is provided on the top of the receiving sleeve. The collar assembly is positioned between the two slots, corresponding to the through hole. The two elastic bands are located on the top of the receiving sleeve, respectively on either side of the through hole. The airbag assembly is located on the receiving sleeve. The two first Velcro surfaces are respectively located on either side of the two slots, and the collar assembly is connected to the first Velcro surfaces. The extension sleeve is located at the bottom of the receiving sleeve.

[0008] In addition, the hand restraint device for preventing accidental tube removal based on the clustering principle proposed in this application may also have the following additional technical features:

[0009] In one embodiment of this application, the ferrule assembly includes a finger ferrule, a movable band, two adhesive members, two extension bands, and a second Velcro group. The finger ferrule is disposed in the middle of the movable band, and the two adhesive members are respectively disposed at both ends of the movable band. The two adhesive members extend from two strip openings. A first Velcro hook surface is provided on the back of each of the two adhesive members. The two extension bands are respectively connected to the two adhesive members, and a second Velcro group is disposed between the two extension bands.

[0010] In one embodiment of this application, the airbag assembly includes an airbag body, a connecting tube, a mounting shell, and a one-way valve. The airbag body is disposed at the bottom of a receiving sleeve, the connecting tube is disposed inside the receiving sleeve, and one end of the connecting tube is connected to the airbag body. The mounting shell is disposed on one side of the receiving sleeve, and an inflation port is provided on the mounting shell. A one-way valve is provided on one side of the inflation port, and the other end of the connecting tube is connected to the one-way valve.

[0011] In one embodiment of this application, the distance between the two adhesive pieces is not less than the distance between the two first hook and loop fastener surfaces.

[0012] In one embodiment of this application, a breathable mesh is provided on the covering surface.

[0013] In one embodiment of this application, the sum of the lengths of the two extension strips is not less than the distance between the two adhesive members.

[0014] In one embodiment of this application, the extension sleeve is elastic.

[0015] In one embodiment of this application, a strap assembly is provided on one side of the bottom of the receiving sleeve. The strap assembly includes a strap body and a third Velcro group, wherein the third Velcro group is disposed on the strap body; the length of the strap body is not less than the width of two of the extension sleeves.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] 1. The zipper connects the receiving sleeve and the covering surface to form a receiving cavity, into which the patient's hand is placed. This allows the patient's hand to be contained and restrained, thereby preventing the patient from accidentally pulling out the tube.

[0018] 2. The provided collar assembly can constrain and limit the position of the patient's finger. When it is necessary to draw blood from the patient, simply press the elastic band on both sides of the through hole, and the through hole will move downward, exposing the fingertip to be drawn, making it easier for medical staff to draw blood from the patient.

[0019] 3. The included airbag assembly can restrain the patient's palm, increasing the restraint effect.

[0020] 4. This device allows medical staff to perform finger-prick blood sampling without removing the restraints, significantly reducing operational steps and workload, shortening blood collection preparation time, and avoiding delays in emergency situations. Simultaneously, it maintains the stability of the restraints, reducing the risk of patients pulling out the catheter and ensuring treatment safety. For patients requiring frequent blood sampling, it reduces hand discomfort caused by repeated disassembly, lowers the probability of blood collection failure, and alleviates patient suffering.

[0028] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0029] The following describes, with reference to the accompanying drawings, a hand restraint device based on the principle of clustering to prevent accidental tube removal, according to an embodiment of this application.

[0030] like Figure 1-Figure 4 As shown, the hand restraint device for preventing accidental tube removal based on the clustering principle in this application embodiment may include a receiving sleeve 1, two elastic bands 2, a covering surface 3, a collar assembly 5, an airbag assembly 6, two first Velcro surfaces 9, and an extension sleeve 7.

[0031] A zipper is provided between the edges of the receiving sleeve 1 and the covering surface 3, forming a cavity that can accommodate the patient's hand. It should be noted that the cavity is used to place the patient's hand, thereby restraining the patient's hand.

[0032] In one embodiment of this application, such as Figure 1As shown, a breathable mesh 4 is provided on the covering surface 3.

[0033] Understandably, the included breathable mesh 4 facilitates ventilation inside the device, preventing the patient's hand from being inside the cavity for extended periods and causing discomfort. Furthermore, the breathable mesh 4 can be replaced with other breathable materials to achieve a similar breathability effect.

[0034] The receiving sleeve 1 has a strip-shaped opening 12, and the top of the receiving sleeve 1 has a through hole 11. Two elastic bands 2 are provided on the top of the receiving sleeve 1, and the two elastic bands 2 are respectively located on both sides of the through hole 11.

[0035] The collar assembly 5 is positioned between the two strip openings 12, and the collar assembly 5 and the through hole 11 are positioned correspondingly.

[0036] It should be noted that the through hole 11 facilitates blood collection by medical staff. Specifically, because the elastic bands 2 on both sides are elastic, and the collar assembly 5 and the through hole 11 are positioned correspondingly, when blood collection is needed, medical staff can press down on the elastic bands 2 on both sides to expose the finger to be collected through the through hole 11 for blood collection.

[0037] Two first hook and loop fastener surfaces 9 are respectively set on both sides of the two strip openings 12, and the collar assembly 5 is connected to the first hook and loop fastener surfaces 9.

[0038] It should be noted that the collar assembly 5 can move up and down between the two slots 12, and the length of the slots 12 is the movable distance of the collar assembly 5.

[0039] In one embodiment of this application, such as Figure 4 As shown, the ferrule assembly 5 includes a finger ferrule 51, a moving band 52, two adhesive pieces 53, two extension bands 54, and a second Velcro assembly 56.

[0040] The finger loop 51 is located in the middle of the moving belt 52, and two adhesive pieces 53 are respectively located at both ends of the moving belt 52. The back of each adhesive piece 53 is provided with a first Velcro hook surface 55, and the two adhesive pieces 53 are respectively passed through the two strip openings 12.

[0041] To further clarify the above embodiments, in one embodiment of this application, such as Figure 3 As shown, when the adhesive 53 passes through the strip opening 12, the first hook and loop fastener 55 on the adhesive 53 can adhere to the first hook and loop fastener 9. The position of the moving belt 52 is determined by the adhesive relationship between the first hook and loop fastener 55 and the first hook and loop fastener 9, thereby determining the position of the finger loop 51.

[0042] It should be noted that the distance between the two adhesive pieces 53 is not less than the distance between the two first hook and loop fastener surfaces 9.

[0043] Two extension straps 54 are connected to two adhesive pieces 53 respectively, and a second Velcro group 56 is provided between the two extension straps 54. It should be noted that the extension straps 54 can be wrapped around the movable strap 52 in a ring through the provided second Velcro group 56, which can keep the finger loop 51 always between the two strip openings 12 and prevent the finger loop 51 from falling off and being lost.

[0044] It should be noted that, in one embodiment of this application, as Figure 4 As shown, the sum of the lengths of the two extension strips 54 is not less than the distance between the two adhesive pieces 53.

[0045] The airbag assembly 6 is disposed on the receiving sleeve 1. In one embodiment of this application, as... Figure 2 As shown, the airbag assembly 6 includes an airbag body 61, a connecting tube 62, a mounting shell 63, and a one-way valve 64.

[0046] The airbag body 61 is located at the bottom of the receiving sleeve 1, and the connecting tube 62 is located inside the receiving sleeve 1, with one end of the connecting tube 62 connected to the airbag body 61. It should be noted that the airbag body 61 fits snugly against the patient's palm.

[0047] The mounting shell 63 is located on one side of the housing 1. An air inlet 65 is provided on the mounting shell 63. A one-way air valve 64 is provided on one side of the air inlet 65. The other end of the connecting pipe 62 is connected to the one-way air valve 64.

[0048] It should be noted that the airbag can support the patient's palm, and by restricting the patient's palm, it can also restrict the behavior of other fingers in conjunction with the collar assembly 5.

[0049] Specifically, when the airbag body 61 needs to be inflated, an external air pump is required to pump gas into the airbag body 61 through the inflation port 65 and the connecting pipe 62, thereby inflating the airbag body 61. The one-way air valve 64 provided can reduce gas leakage.

[0050] The extension sleeve 7 is located at the bottom of the receiving sleeve 1, and the extension sleeve 7 is elastic.

[0051] Understandably, the included extension sleeve 7 can restrict and constrict the patient's wrist.

[0052] In one embodiment of this application, such as Figure 1 As shown, a strap assembly 8 is provided on one side of the bottom of the receiving sleeve 1. The strap assembly 8 includes a strap body 81 and a third Velcro group 82.

[0053] The third Velcro group 82 is set on the strap body 81, and the length of the strap body 81 is not less than the width of the two extension sleeves 7.

[0054] It should be noted that the strap assembly 8 provided in this embodiment can wrap around and secure the extension sleeve 7, further strengthening the restraint on the extension sleeve 7 and preventing the patient's hand from being removed from the extension sleeve 7.

[0055] Specifically, when medical staff need to put the device on a patient, they first unzip the zipper between the receiving sleeve 1 and the covering surface 3, then insert the patient's extension sleeve 7 and place it inside the receiving cavity. Next, the two adhesive pieces 53 are moved, causing the moving belt 52 to move, so that the finger loop 51 is slipped onto the patient's middle finger and positioned at the finger joint.

[0056] After determining the position of the finger loop 51, press down on the two adhesive pieces 53 respectively, so that the adhesive pieces 53 adhere to each other through the first hook and loop hook surface 55 and the first hook and loop hook surface 9, thereby completing the determination of the position of the moving strap 52 and the finger loop 51. Then zip up the zipper, bend the extension straps 54 on both sides, and use the second hook and loop hook group 56 to adhere the two extension straps 54 together.

[0057] Afterwards, an air pump is connected to the inflation port 65 to inflate the airbag. The airbag body 61 supports and restricts the patient's palm. Finally, the wrist is reinforced by wrapping the strap body 81 around the extension sleeve 7.

[0058] When medical staff need to draw blood from a patient's fingertip, they only need to press down on the elastic bands 2 on both sides, and the finger to be drawn will be exposed at the through hole 11 so that medical staff can draw blood.

[0059] In summary, the hand restraint device based on the clustering principle for preventing accidental extubation in this application embodiment allows medical staff to perform finger-prick blood sampling without removing the restraint device, significantly reducing operational steps and workload, shortening blood sampling preparation time, and avoiding delays in treatment during emergencies. Simultaneously, it maintains the stability of the restraint device, reducing the risk of patients accidentally removing the tube and ensuring treatment safety. For patients requiring frequent blood sampling, it reduces hand discomfort caused by repeated disassembly, lowers the probability of blood sampling failure, and alleviates patient suffering.
