Description

Technology Field

[0001] The present invention relates to a catheterization practice model device that allows medical personnel, who must care for patients and perform appropriate procedures or treatments, to practice using a model similar to the human body. Background Technology

[0003] Due to rapid aging, the elderly population is expected to exceed 20% by 2025, and many social and economic changes and problems are emerging as a result of entering a super-aged society.

[0004] In particular, as health issues among the elderly are becoming a significant social issue and the necessity of geriatric nursing is being emphasized accordingly, the training of specialized personnel for geriatric nursing is required.

[0005] Important nursing skills related to geriatric care include urinary management (catheter insertion), blood glucose management (subcutaneous injection), and bowel management (enema).

[0006] Catheterization refers to the use of a catheter to drain urine when it accumulates in the bladder due to various causes and does not come out at all or only partially.

[0007] A catheter is inserted into the bladder through the urethra, and leaving the catheter in place is called indwelling catheterization; this is a method used until the surgical wound has fully healed following surgery on the bladder or urethra.

[0008] The Foley catheter used for indwelling urination is an indwelling catheter primarily used in the field of urology. Its structure consists of a balloon-shaped pouch attached to the tip and two injection ports on the other side. The cross-section of the catheter contains a hole for inflating the balloon at the tip and a hole for draining urine. When the catheter is indwelled, air or distilled water is injected into the balloon. Meanwhile, when removing the catheter, the procedure involves first deflating the balloon and then removing the catheter.

[0009] Meanwhile, when inserting a catheter, it must be inserted accurately through the urethra into the bladder; if the catheter is inserted incorrectly, secondary damage may occur through urethral injury, urethral infection, and bladder infection. Additionally, in women, inserting the catheter into the vagina instead of the urethra can cause vaginal infection.

[0010] Therefore, as patient safety depends on the operator's safe and proficient catheterization ability, catheterization is a skill that requires both knowledge and competence, necessitating extensive repetitive practice to achieve mastery. Catheterization practice should be conducted through continuous education, regular practice, and practical training tailored to individual capabilities. However, in reality, there are significant difficulties in conducting repetitive catheterization practice on actual human bodies.

[0011] Furthermore, subcutaneous injection and enema are also important nursing skills, so it is necessary to master these techniques through repetitive practice.

[0012] A "catheterization practice model" of Korean Registered Patent No. 10-1848627 is known as prior art related to the present invention, and FIG. 1 is a perspective view of a paint practice model according to the prior art, and FIG. 2 is an exploded perspective view of FIG. 1.

[0013] A catheterization practice model according to the prior art includes a buttocks (110), a genital area (120), and an artificial urine supply area (130). The buttocks (110) are manufactured to resemble the lower body of a human body and allow a male external genitalia model (127) or a female external genitalia model to be attached through an opening (110a) on one side.

[0014] The genital portion includes a genital module (121), a backflow prevention module (123), a bladder (125), etc., and the genital portion is detachably connected to the buttocks. The genital module (121) includes a housing (1211), a urethra (1213), and a connecting portion (1215).

[0015] Although conventional technology can be usefully applied for practice in catheter insertion procedures for urinary catheterization, it has the disadvantage that when practicing catheterization in male patients, the insertion depth cannot be verified due to the longer urethra characteristic of men, and even if the catheter is inserted, it cannot provide confidence to trainees because it cannot be visually confirmed that it has reached the bladder.

The camera part (410) is positioned to face the opening hole (110) formed in the buttocks model (100) so as to be able to photograph the catheter insertion situation during catheterization practice.

[0043] A buttock model (100) forming a catheterization practice model device according to the present invention may have a first hole (120) formed therein, the first hole (120) corresponds to a human anus, the first hole (120) is formed on the lower side of a genital model (200), and an anus module (500) is coupled to the first hole (120).

[0044] The anal module (500) is provided for practicing anal enema, and preferably, the anal module (500) consists of a skin portion (510) that is connected to the first hole (120) and exposed to the outside, and a drainage hose (520) that is connected to the back side of the skin portion (510) and extends into the buttocks model body (100). In addition, an anal hole (511) connected to the first hole (120) is formed in the center of the skin portion (510), and the drainage hose (520) is connected to the anal hole (511).

[0045] In addition, the catheterization practice model device according to the present invention may be equipped with a subcutaneous injection module (600), preferably, an opening (130) may be formed on the upper surface (corresponding to the abdominal area) of the buttock model body (100), and a subcutaneous injection module (600) forming an abdominal shape may be coupled to the opening (130).

[0046] The subcutaneous injection module (600) is made of a material such as silicone that can feel like real skin, allowing for practice by inserting a real syringe.

[0047] The camera module (400) is composed of a camera unit (410) and a wire (420), wherein one end of the wire (420) is connected to the camera unit (410) and the other end is connected to a control board (700). A communication module (710) is provided on the control board (700), and the image captured by the camera unit (410) is transmitted to a user terminal via the communication module (710).
