Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an auxiliary tool for collecting saliva from patients with ALS. Background Technology

[0002] Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is a chronic, progressive neurological disorder that primarily damages the upper and lower motor neurons and the muscles they innervate in the trunk, limbs, and face.

[0003] Excessive salivation is a common problem in patients with amyotrophic lateral sclerosis (ALS). This is due to weakness in the tongue and throat muscles, which prevents the automatic swallowing of saliva that accumulates in the mouth. Saliva buildup can cause choking, disrupt sleep, and easily stain clothing collars.

[0004] Therefore, designing an assistive tool that prevents saliva from splashing and dripping and causing contamination, while also being able to collect saliva from ALS patients, has become an urgent problem to be solved in the field of medical device technology. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary tool for collecting saliva from patients with ALS. The mask can prevent the patient's saliva from splashing and dripping, thus preventing contamination. The mask and the collection bag are connected by a tube, allowing the patient's saliva to be collected into the collection bag.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] A saliva collection aid for patients with ALS includes a mask, straps, a catheter, and a collection bag. The mask includes a support and a cover plate. The cover plate is located on top of the support and is tilted outward. The two ends of the straps are respectively connected to the two ends of the support. The mask is worn through the straps, which are wrapped around the back of the patient's head. The inner surface of the support fits the patient's chin, and the cover plate covers the patient's mouth. A saliva outlet is provided on the lower outer side of the cover plate. A catheter is provided at the upper end of the collection bag, and the outer end of the catheter is connected to the saliva outlet, so that the collection bag hangs outside the mask and the patient's saliva flows from the saliva outlet into the collection bag.

[0008] Preferably, there are three liquid outlets, one of which is located at the midpoint of the lower edge of the cover plate, and the other two are located at the two ends of the lower edge of the cover plate, with sealing parts on the outer cover of the liquid outlets.

[0009] Preferably, a cavity is provided inside the sealing member. A moisture-absorbing core is filled in the cavity of the sealing member. The moisture-absorbing core is made of high water-absorbing resin material. The sealing member is provided with a liquid collecting head, and the liquid collecting head is threadedly connected to the liquid outlet, so that the patient's saliva flows into the cavity through the liquid collecting head and is absorbed by the moisture-absorbing core. By absorbing saliva with the moisture-absorbing core, it is possible to prevent the saliva from flowing back to the patient's mouth and causing discomfort to the patient.

[0010] Preferably, the moisture-absorbing pad is fixedly adhered to the inner surface of the mask through a magic tape. The medical staff can replace the moisture-absorbing pad on the mask.

[0011] Preferably, a moisture-absorbing pad is provided on the inner surface of the mask. The moisture-absorbing pad is in a "U" shape and is arranged along the left, lower, and right sides of the mask. The moisture-absorbing pad is made of high water-absorbing resin material. The moisture-absorbing pad is elastic and conforms to the patient's skin, which can relieve the pressure of the mask and make the patient wear comfortably; the moisture-absorbing pad can also absorb saliva and prevent the saliva from overflowing from the peripheral gap of the mask and causing pollution.

[0012] Preferably, a rotatable rotary joint is provided at the outer end of the catheter, and the rotary joint is threadedly connected to the liquid outlet. Since the rotary joint can rotate, when the medical staff rotates the rotary joint, it will not cause the catheter to twist, which is convenient for disassembling and assembling the catheter at the liquid outlet.

[0013] Preferably, the strap includes a drawstring and two hanging straps. The hanging straps are in a ring shape. The two hanging straps are respectively fixed at both ends of the mask holder. The two hanging straps are respectively hung on the patient's ears. A buckle is provided at the end of the hanging strap far from the mask holder. The two ends of the drawstring respectively pass through the two buckles and are fixedly adhered through a magic tape. The hanging straps can prevent the mask from accidentally falling off, and the drawstring can adjust the length of the strap, which is suitable for the heads of patients with different body types.

[0014] Preferably, an anti-pressure pad is provided on the surface of the drawstring that fits the back of the patient's head. The anti-pressure pad is made of rubber sponge material. By means of the anti-pressure pad, the pressure of the drawstring is relieved, making the patient wear comfortably.

[0015] Compared with the prior art, the saliva collection assistance tool for patients with amyotrophic lateral sclerosis adopting the above technical solution has the following beneficial effects:

[0016] When using the saliva collection assistance tool for patients with amyotrophic lateral sclerosis of the present utility model, the patient with amyotrophic lateral sclerosis wears a mask, and the mask can prevent the patient's saliva from splashing and flowing down and causing pollution: when the patient is in a sitting position, the medical staff connects the catheter to the liquid outlet in the middle of the mask plate, and the saliva splashed onto the inner surface of the mask plate will flow downward and incline into the liquid outlet, and is collected into the liquid collection bag through the catheter; when the patient is in the left lateral position, the medical staff connects the catheter to the liquid outlet at the left end of the mask plate, and the saliva flowing from the left corner of the patient's mouth will enter the liquid outlet and is collected into the liquid collection bag through the catheter; when the patient is in the right lateral position, the medical staff connects the catheter to the liquid outlet at the right end of the mask plate, and the saliva flowing from the right corner of the patient's mouth will enter the liquid outlet and is collected into the liquid collection bag through the catheter.

[0017] In the preferred option, medical staff can select one of the three outlets to connect a catheter as needed, and seal the other two outlets with a sealing device to prevent the patient's saliva from flowing out of the other two outlets and causing contamination. The same mask is suitable for both the patient's side-lying and sitting positions. Attached Figure Description
