Detailed Description

The utility model will now be further described with reference to the drawings and specific examples.

Referring to fig. 1-4, an Ommaya capsule puncture drainage external fixation device is disclosed in the embodiment of the utility model, which comprises a device body 1, wherein the device body 1 can be adhered on the scalp, and a scalp needle 6 is fixed on the device body 1, so that the fixation of the scalp needle 6 and a drainage tube 7 is realized.

Referring to fig. 1, the device body 1 has a trapezoid shape in side view, the device body 1 has a top surface 12, one base angle of the device body 1 is 30 ° at a first base angle 2, a corresponding inclined surface of the first base angle 2 is a first inclined surface 11, the other base angle of the device body 1 is 45 ° at a second base angle 3, and a corresponding inclined surface of the second base angle 3 is a second inclined surface 13. The liquid storage bag 8 is arranged on one side of the device body 1, which is close to the first bottom corner 2, after the scalp needle 6 penetrates into the liquid storage bag 8, the tail end of the scalp needle 6 and the drainage tube 7 are fixed on the first inclined plane 11, and after the scalp needle 6 is covered on the top surface of the device body 1 along the way, the scalp needle 6 is fixed on the second inclined plane 13 along the way. The angle acting on the first base angle 2 is an acute angle of 30 degrees, and is matched with the angle of penetrating the scalp needle 6 into the liquid storage bag 8, so that the drainage tube 7 cannot be bent, and the drainage is smoother.

The front end of the scalp needle 6 can be immersed into the scalp and the liquid storage bag 8, so that the tail end of the scalp needle 6 is fixed to ensure that the puncture direction does not damage the liquid storage bag 8, and repeated displacement of the drainage tube 7 caused by head swing does not occur, so that drainage fails.

The fixation of the drainage tube 7 by the second bevel 13 further enhances the stability of the scalp needles 6 and 7.

The device body 1 has the purpose of ensuring the puncture direction, and the scalp needle 6 and the drainage tube 7 are firmly fixed on the scalp.

The device body 1 is secured to the scalp of a patient by means of a stretch-proof adhesive tape 10. The stretch-proof adhesive tape 10 can be purchased directly from the market, and specific technical parameters thereof are disclosed, so that detailed description thereof is omitted herein.

Specifically, referring to fig. 2-4, the scalp needle 6 and the drainage tube 7 are fixed by the device body 1, in which the first inclined plane 11, the top plane 12 and the second inclined plane 13 of the device body 1 are provided with the containing groove 4 inwards, the section of the containing groove 4 is round, which is matched with the scalp needle 6 and the drainage tube 7, the device body 1 is provided with an upper opening 5 for the scalp needle 6 and the drainage tube 7 to enter and exit the containing groove 4, under the condition of no stress, the opening of the upper opening 5 is smaller than the outer diameters of the scalp needle 6 and the drainage tube 7, so that the scalp needle 6 and the drainage tube 7 are prevented from being separated from the containing groove 4 under the condition of no manual operation after being clamped into the containing groove 4.

As shown in fig. 3, a handle 9 for facilitating the medical staff to hold the scalp needle 6 for puncturing is fixed on the needle handle of the scalp needle 6, and when the needle handle of the scalp needle 6 is embedded in the opening 5, the handle 9 is embedded in the opening 5 so as to fix the needle handle of the scalp needle 6 and prevent the scalp needle 6 from shaking and rotating to both sides.

The middle part of the easy-to-draw tape 10 (3M brand is preferred in the embodiment) is adhered on the first inclined surface 11 of the device body 1, and the easy-to-draw tape 10 is adhered on one side of the handle 9 away from the needle head of the scalp needle 6 and can be propped against the side of the handle 9 away from the needle head of the scalp needle 6, so that the scalp needle 6 is limited, and the backward movement of the scalp needle 6 is limited.

The both sides of the pull tape 10 are preferably adhered to the scalp of the patient, thereby securing the device body 1 to the scalp of the patient. And set up top surface 12, can make the better fixing device body 1 of easy-to-draw sticky tape, also make the drainage tube when the transition from first inclined plane 11 to second inclined plane 13, the angle of buckling is littleer, is difficult for taking place because of the too big jam that leads to drainage tube 7 of angle of buckling.

The scalp needle 6 is commonly used with the model numbers of 8, 7, 4.5 and the like. The 4.5 gauge scalp needle 6 is too short, so the embodiment selects the 7 gauge scalp needle 6 which is more slender, and in practical application, the scalp needle 6 with larger specification can be considered

The scalp to skull thickness is often 0.9-1.2CM, plus 8, greater than 1CM. Therefore, the first inclined surface 11 should be larger than 2CM to increase the adaptability, the length of the needle head part is smaller than 4.3CM, and the length of 2.5CM adopted by the first inclined surface 11 in the embodiment is deducted, and the length of the scalp part entering the scalp subcutaneous part is smaller than 2CM. The first bevel 11 accommodates the entire shank of the scalp needle 6 after the scalp needle 6 is pierced. The bottom of the device body 1 is arc-shaped which is suitable for the head of a patient, and is more convenient for fitting the head of the patient.

The reasonable length, the angle and the fixing of each direction of each surface of the device are considered, and the materials are simply and practically obtained.

In this embodiment, the device body 1 is made of elastic silica gel, and the needle handle portion of the scalp needle 6 and the drainage tube 7 can be clamped into the accommodating groove 4 through the upper opening 5, and the structure after clamping refers to fig. 2. Because the device body 1 has elasticity, when the scalp needle 6 and the drainage tube 7 are to be clamped into the accommodating groove 4, the upper opening 5 can be opened by the scalp needle 6 or the drainage tube 7, so that the scalp needle 6 and the drainage tube 7 can enter into the accommodating groove 4, and then the width of the upper opening 5 is reduced, so that the scalp needle 6 and the drainage tube 7 are prevented from being separated from the device body 1 when no manual operation is performed.

Based on the above embodiment, the device body 1 may be made of other elastic materials.

Based on the above technical scheme, the holding groove 4 located on the first inclined plane 11 can also be used as a guiding groove, after the position of the device body 1 on the scalp of a patient is preliminarily fixed by hands, the scalp needle 6 is penetrated from the top of the holding groove 4 on the first inclined plane 11, the handle 9 is located in the opening 5, the handle 9 is partially exposed out of the opening 5, medical staff can puncture the scalp needle 6 into the liquid storage bag 8 by pushing the exposed part of the handle 9, so that the puncture angle of the puncture needle 6 is ensured to meet the requirement, and then the device body 1 is fixed by using the stretchable adhesive tape 10.

Modifications and variations made by the subject matter are intended to be within the scope of the claims and are not limited to the embodiments disclosed.
