Description

Technical Field

[0001] The utility model relates to the field of medical appliances, in particular to a debridement fixator used for spreading finger gaps. Background Art

[0002] The main causes of finger ulcers are trauma, fungal infection, eczema, etc.

[0003] 1. Trauma: If the patient has a history of trauma, such as puncture, cut, etc., if the wound is not handled properly, or the wound comes into contact with water, it may cause wound infection and symptoms such as suppuration. If it is caused by trauma, you need to go to the hospital for surgical treatment, perform thorough debridement of the wound, and then use anti-infection drugs for treatment.

[0004] 2. Fungal infection: Symptoms of ulceration on the fingers may be caused by erosive tinea manuum, which may be accompanied by discomfort symptoms such as itching. In this case, external application of terbinafine ointment can be used for treatment.

[0005] 3. Eczema: This is an allergic skin disease. Infection can worsen eczema and cause ulcers. It can be treated with topical iodine ointment or fusidic acid ointment. Oral antihistamines such as cetirizine and olopatadine are also options.

[0006] Finger ulcers usually form between the fingers. During treatment, medical staff need to open the patient's fingers and apply liquid medicine. After applying the liquid medicine, the wound needs to be dried. Sometimes, the side walls of the patient's fingers cannot be allowed to touch each other, otherwise the side walls of the two fingers will stick together, which can easily lead to wound erosion.

[0007] The shortcomings of the above technologies are:

[0008] 1. Patients may easily close their fingers if they are not careful.

[0009] 2. Hemiplegic patients are unable to open their fingers by themselves. Medical staff usually use one hand to pry open the patient's fingers and then use the other hand to apply medicine. During the drying process of the medicine, the patient's two fingers need to be fixed for a long time, which increases the workload of medical staff. Utility Model Content

[0010] The purpose of the utility model is to provide a debridement fixator for spreading the finger gaps, which uses two support rods to spread the patient's finger gaps, thereby preventing the patient from accidentally closing the finger gaps during the drying process of the medicine application, thereby preventing wound erosion. Moreover, for hemiplegic patients, the debridement fixator can replace the need to fix the patient's two fingers by hand, thereby reducing the workload of medical staff.

[0011] In order to achieve the above-mentioned purpose of the invention, the present invention adopts the following technical solutions:

[0012] A debridement fixator for spreading finger gaps comprises a fixing block having a head end and a tail end, the head end of which can be inserted into a patient's finger gap. Retractable struts are provided on either side of the fixing block, the two struts moving closer and farther away from each other. A retractable push rod is provided at the tail end of the fixing block, and a linkage head in the form of an isosceles triangle is provided at the retracted end of the push rod. The retracted ends of the two struts are respectively pressed against the two waist surfaces of the linkage head. The push rods extend and retract in a direction perpendicular to the direction in which the struts extend and retract. When the push rods are retracted, the two struts spread the patient's finger gaps.

[0013] Preferably, the support rod is provided with an elastic sheet, and the extension and contraction direction of the elastic sheet is the same as that of the support rod: when the support rod is extended, the elastic sheet is compressed, and when the support rod is retracted, the elastic sheet is reset. The support rod can be automatically retracted into the fixed block by the elastic sheet.

[0014] Preferably, the fixed block is connected to a rotatable coil at its rear end, and the extended end of the push rod is threaded into the coil. When the coil rotates forward, the push rod screws into the fixed block, pushing the two struts away from each other and compressing the spring. When the coil rotates backward, the push rod screws out of the fixed block, and the spring returns, bringing the two struts closer together. By rotating the coil, medical staff can adjust the distance between the patient's fingers as needed, ensuring optimal finger comfort.

[0015] Preferably, a grip is provided at the end of the coil, and the end of the coil is fixed vertically to the midpoint of the grip in a T-shape. The coil can be easily rotated by turning the grip.

[0016] Preferably, an anti-pressure pad is provided at the protruding end of the support rod, and the anti-pressure pad is made of elastic silicone material. The anti-pressure pad can relieve the pressure of the support rod on the skin between the patient's fingers, thereby improving comfort.

[0017] Preferably, a base is provided below the fixing block, and the patient's two fingers are placed on the base and clamped on both sides of the fixing block. The base is used to raise the patient's fingers, providing medical staff with enough space to rotate the coil.

[0018] Preferably, the base is provided with a timer, an alarm, and a timing button. The timer is coupled to the alarm and the timing button. When the timing button is pressed, the timer begins to count down. When the countdown ends, the alarm is triggered to emit an alarm signal. The alarm can be an LED light and a speaker. The alarm notifies medical staff that the patient's finger joints have reached the drying time.

[0019] Preferably, a groove is provided on the base, and the groove is provided at the end of the fixed block, so that the patient's fingers are suspended below. The groove allows the patient's fingers to be suspended, and the liquid medicine applied to the fingers will drip into the groove, thereby preventing the liquid medicine from accumulating between the fingers and the base and making it difficult for the fingers to dry.

[0020] Compared with the existing technology, the debridement fixator for finger opening using the above technical solution has the following beneficial effects:

[0021] 1. When using the debridement fixator for spreading the finger gaps of the utility model, the medical staff aligns the head end of the fixing block with the finger gap and inserts it, then retracts the push rod by rotating the rotary tube. The two waist surfaces of the linkage head play a transition role, so that the two support rods spread the patient's finger gaps and keep the patient's finger gaps open, maintaining better air permeability, and avoiding the patient's accidental closing of the finger gap during the drying process of the application of the medicine, which may cause wound erosion.

[0022] 2. Moreover, for hemiplegic patients, the debridement fixator can replace the use of hands to fix the patient's two fingers, reducing the workload of medical staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0030] like Figures 1 to 5The debridement fixator shown for spreading the finger webs includes a fixing block 1. The two ends of the fixing block 1 are respectively a head end and a tail end. The head end of the fixing block 1 can be placed into the finger webs of the patient. Telescopic struts 12 are respectively arranged on both sides of the fixing block 1. The two struts 12 approach and move away from each other. A telescopic push rod 11 is arranged at the tail end of the fixing block 1. A linkage head 13 in the shape of an isosceles triangle is arranged at the retracted end of the push rod 11. The retracted ends of the two struts 12 are respectively pressed on the two waist surfaces of the linkage head 13. The telescopic direction of the push rod 11 is perpendicular to the telescopic direction of the struts 12. A spring piece 14 is arranged on the strut 12. The telescopic direction of the spring piece 14 is the same as the telescopic direction of the strut 12. A rotatable screw tube 15 is connected to the tail end of the fixing block 1. The extended end of the push rod 11 is threadedly connected into the screw tube 15: when the screw tube 15 rotates forward, the push rod 11 is screwed into the fixing block 1, pushing the two struts 12 to move away from each other and compressing the spring piece 14; when the screw tube 15 rotates backward, the push rod 11 is screwed out of the fixing block 1, and the spring piece 14 resets to make the two struts 12 approach each other. Medical staff align the head end of the fixing block 1 with the finger webs and place it in, and then rotate the screw tube 15 to retract the push rod 11. The two waist surfaces of the linkage head 13 play a transitional role, enabling the two struts 12 to spread the finger webs of the patient, keeping the finger webs of the patient open, maintaining better air permeability, and preventing the patient from accidentally closing the finger webs during the process of applying medicine and drying, resulting in wound erosion; moreover, for hemiplegic patients, the debridement fixator can replace manually fixing the two fingers of the patient, reducing the workload of medical staff.

[0031] Among them, medical staff can adjust the distance between the two fingers of the patient according to needs by rotating the screw tube 15, so that the comfort of the finger webs of the patient is better.

[0032] Refer to Figure 4 , a grip rod 16 is arranged at the end of the screw tube 15. The end of the screw tube 15 is vertically fixed at the midpoint of the grip rod 16 and is in a "T" shape. It is easier to rotate the screw tube 15 by flipping the grip rod 16.

[0033] Refer to Figure 1 , an anti-pressure pad 17 is arranged at the extended end of the strut 12. The anti-pressure pad 17 is made of elastic silicone material. The pressure of the strut 12 on the skin of the finger webs of the patient is relieved through the anti-pressure pad 17, improving the comfort.

[0034] Refer to Figure 2 , a base 2 is arranged under the fixing block 1. The two fingers of the patient are placed on the base 2 and clamped on both sides of the fixing block 1. The fingers of the patient are raised by the base 2, providing enough space for medical staff to rotate the screw tube 15.

[0035] Among them, a timer, an alarm 21 and a timing button 22 are arranged on the base 2. The timer is coupled to the alarm 21 and the timing button 22. The alarm 21 uses an LED lamp. When the timing button 22 is pressed, the timer starts counting down. When the countdown ends, the LED lamp of the alarm 21 is triggered to emit red light. Through the prompt of the alarm 21, medical staff can know that the finger webs of the patient have reached the drying time.

[0036] Reference Figure 3 The base 2 is provided with a groove 23 at the top end of the fixing block 1, so that the patient's fingers are suspended in the air. The groove 23 allows the patient's fingers to be suspended in the air, and the liquid medicine applied to the fingers will drip into the groove 23, preventing the liquid medicine from accumulating between the fingers and the base 2 and making it difficult for the fingers to dry.
