Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment and relates to a drainage fixing bracket. Background Art

[0002] Clinically, after brain surgery, the height at which the drainage bag is hung varies depending on the placement of the drainage tube within the skull, and strict requirements apply: for example, ventricular drainage requires the bag to be level with the forehead or elevated 15 cm above the external auditory canal. The height of the drainage bag should be adjusted based on the patient's condition. If the bag is too high, insufficient drainage can lead to increased intracranial pressure and, in severe cases, brain herniation. If the bag is too low, excessive drainage can cause intracranial hypotension and lead to cerebral hemorrhage. Both of these factors can directly worsen the patient's condition or even cause death.

[0003] A Chinese patent (CN20250133U) discloses a medical external ventricular drainage tube fixing bracket. When in use, the entire bracket can be fixed to the patient's bedside via a bedside clamp. After the standard position relative to the patient's head is determined using a telescopic positioning rod, the appropriate height of the hook is adjusted and the bracket is fixed by tightening the adjusting nut. The external ventricular drainage tube used by the patient can be hung on the hook. Since both the height of the hook and the overall height of use can be adjusted, the fixing and use of the drainage tube can be extremely convenient.

[0004] However, there is no corresponding scale on the telescopic positioning rod in the above-mentioned fixed bracket, and the hanging height of the drainage bag is the sum of the telescopic length of the telescopic positioning rod and the length from the hook to the telescopic positioning rod, which cannot exceed 15 cm. Since the telescopic positioning rod is not marked with a scale, the hanging height of the drainage bag is inaccurate. Utility Model Content

DETAILED DESCRIPTION

[0030] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0031] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0032] like Figure 1 and Figure 2 As shown, the present invention provides a drainage fixing bracket, comprising:

[0033] The support 10 is provided with a receiving cavity 11 connected to the object to be connected, and a first adjustment portion 20 for changing the size of the opening of the receiving cavity 11. When the receiving cavity 11 is connected to the object to be connected, the first adjustment portion 20 can lock or release the connection between the support 10 and the object to be connected;

[0034] The column 30 is connected to the support 10 and is located on the back side of the bottom of the accommodating cavity 11;

[0035] The sliding rod 40 forms a sliding engagement with the column 30 and is provided with a second adjustment portion 50 on the sliding rod 40, which is used to lock or release the current position of the sliding rod 40 on the column 30. The two ends of the sliding rod 40 along the sliding direction are a reference end and a hanging end, respectively. The reference end is provided with a lever 41, and the hanging end is provided with at least one hook 42 for hanging a drainage bag.

[0036] The ruler box 70 with a built-in measuring ruler 60 is detachably connected to the lever 41, and the zero point position of the measuring ruler 60 is on the same horizontal plane as the reference plane. The distance between the zero point position of the measuring ruler 60 and the patient's forehead is a variable distance, and the distance between the zero point position of the measuring ruler 60 and the hook 42 on the hanging end is a constant distance, and the sum of the variable distance and the constant distance is not greater than the preset distance for hanging the drainage bag.

[0037] It is worth mentioning that the object to be connected is generally the bed board at the head of the hospital bed, that is, the accommodating cavity 11 on the support 10 forms a snap fit with the bed board, and the connection between the support 10 and the bed board is locked or released through the first adjustment part 20.

[0038] The utility model provides a drainage fixing bracket, which can accurately control the distance between the hook 42 on the hanging end and the patient's forehead within the preset distance range of the drainage bag hanging through the measuring ruler 60, thereby preventing the height of the drainage bag hung on the hook 42 from being too high or too low, thereby improving the safety and reliability of the patient during the drainage process.

[0039] Preferably, the first adjustment portion 20 includes a first adjustment member 21 screwed on the cavity wall of the accommodating cavity 11, and a pad 22 connected to the end of the first adjustment member 21, wherein the relative distance between the cavity wall on the side where the first adjustment member 21 is located and the pad 22 is changed by rotating the first adjustment member 21.

[0040] In this embodiment, the provision of the spacer 22 increases the contact area between the first adjustment portion 20 and the object to be connected, preventing the drainage bag from shifting due to unstable installation of the fixing bracket, thereby ensuring the safety of the patient during the drainage process. Furthermore, the provision of the spacer 22 prevents damage to the surface of the object to be connected.

[0041] It is worth mentioning that an anti-slip pad 23 is provided on the side of the pad 22 away from the first adjusting member 21 to increase the friction between the pad 22 and the object to be connected.

[0042] In addition, the second adjusting portion 50 is a second adjusting member, and the structure of the second adjusting member is the same as that of the first adjusting member 21 , both being a plum handle screw.

[0043] Preferably, a fixing sleeve 12 is provided on the back side of the bottom of the accommodating cavity 11 on the support 10, and one end of the column 30 is inserted into the fixing sleeve 12, wherein the column 30 and the fixing sleeve 12 are connected by fasteners.

[0044] It is worth mentioning that the number of fasteners between the column 30 and the fixing sleeve 12 can be multiple, generally three, and the connection positions of the three fasteners are distributed in a triangular shape, thereby further improving the firmness of the connection between the column 30 and the fixing sleeve 12.

[0045] Preferably, the lever 41 is connected to the slide rod 40 through a connecting plate 43, and the connecting plate 43 is L-shaped. One end of the connecting plate 43 is connected to the slide rod 40 through a fastener, and the other end of the connecting plate 43 forms a rotational fit with the lever 41, wherein one end of the lever 41 serves as the connection position of the ruler box 70.

[0046] In this embodiment, by rotating the lever 41 and the connecting plate 43, when the lever 41 is in use, the length direction of the lever 41 is perpendicular to the moving direction of the slide rod 40. When the hanging distance of the drainage bag is adjusted, the lever 41 can be rotated so that the lever 41 and the slide rod 40 are at a certain angle to achieve the storage of the lever 41, thereby avoiding the patient from colliding with the lever 41 when getting up or lying down, thereby improving the safety of the fixed bracket.

[0047] It is further pointed out that in order to ensure that the lever 41 does not automatically swing down when it is not in use, a pulling portion 44 can be provided on the slide rod 40 so that the angle between the lever 41 and the slide rod 40 is constant when not in use, wherein the pulling portion 44 can be a magnet, and the magnet is installed on the slide rod 40. When the lever 41 is not in use, the lever 41 can be magnetically attracted to the magnet. At this time, the lever 41 and the slide rod 40 are parallel to each other, thereby realizing the "storage" of the lever 41.

[0048] It's worth noting that the end of the connecting plate 43 connected to the slide rod 40 is hidden within the slide rod 40. When the lever 41 is in use, a "seesaw" structure is formed between the lever 41 and the connecting plate 43. One end of the lever 41 serves as the connection point for the ruler box 70, while the other end of the lever 41 abuts the connecting plate 43. The greater the force applied to the end of the lever 41 where the ruler box 70 resides, the tighter the abutment between the other end of the lever 41 and the connecting plate 43, further enhancing the safety of the fixed bracket during use.

[0049] Further preferably, the lever 41 and the ruler box 70 are plug-fitted to facilitate installation and removal of the ruler box 70.

[0050] Preferably, a snap-fit ​​structure 80 is provided between the support 10 and the ruler box 70 , or between the column 30 and the ruler box 70 .

[0051] In this embodiment, the clip structure 80 is used to store the ruler box 70 when it is not in use, so as to prevent the ruler box 70 from always hanging on the lever 41 and causing the patient to collide with it when getting up or lying down, thereby improving the safety of the fixed bracket and preventing the ruler box 70 from having nowhere to put when it is not in use and causing it to be lost.

[0052] It is further pointed out that the snap structure 80 includes a snap connector 81 and a plug connector 82 that can realize male and female plug-in cooperation, and the snap connector 81 is connected to the support 10 or the column 30, and the plug connector 82 is connected to the ruler box 70.

[0053] It is worth mentioning that the positions of the clamping member 81 and the plug-in member 82 can be interchanged, such as connecting the plug-in member 82 to the support 10 or the column 30 , and connecting the clamping member 81 to the ruler box 70 .

[0054] It is further pointed out that the connection between the clamping part 81 and the support 10 and the column 30 can be fixed by means of adhesive backing or fastener connection, and the connection between the plug-in part 82 and the ruler box 70 can also be fixed by means of adhesive backing or fastener connection.

[0055] In this embodiment, when the measuring ruler 60 is needed to adjust the height, the ruler box 70 can be plugged into the lever 41; when the height adjustment is completed, the ruler box 70 can be plugged into the support 10 or the column 30 for storage.

[0056] Preferably, there can be two hooks 42, which are located on both sides of the column 30, and the two hooks 42 are respectively connected to the column 30. By setting two hooks 42, it is convenient to hang multiple drainage bags at the same time, and it can also avoid bending of the drainage tubes on multiple drainage bags, which is conducive to normal drainage of the drainage bags.

[0057] Further preferably, the two hooks 42 are connected by a hanging rod 45, and the hanging rod 45 passes through both sides of the hanging end of the sliding rod 40, and the connection between the hanging rod 45 and the sliding rod 40 is locked by a fastener, wherein the two hooks 42 are respectively located at both ends of the hanging rod 45, and the hook 42 and the hanging rod 45 are detachably connected, and the detachable connection can be a plug-in connection, or a threaded connection, etc.

[0058] In this embodiment, the hook 42 is detachably connected to the hanging rod 45, allowing medical personnel to disassemble and adjust the hook 42 at any time according to the patient's condition, thereby improving the flexibility of the fixed bracket. Furthermore, the two hooks 42 are symmetrically arranged on the hanging rod 45, enhancing the aesthetics of the entire fixed bracket. Furthermore, the hooks 42 are hung toward the column 30, ensuring that any drainage bag hung on the same hook 42 will not be completely obscured by the previous drainage bag. This facilitates medical personnel to promptly observe the drainage status and make appropriate judgments, thereby improving patient safety during drainage.
