Description

Technical Field

[0001] The utility model relates to the technical field of bone marrow cavity infusion, in particular to a bone marrow cavity infusion patch. Background Art

[0002] Intraosseous infusion refers to the method of opening the intraosseous cavity with bone marrow puncture technology in an emergency situation, and administering drugs and infusions through an indwelling puncture needle. It is a technique for quickly establishing vascular access. It is often used in critically ill patients who cannot quickly establish intravenous access due to severe trauma, dehydration, shock, cardiac arrest, etc. During intraosseous infusion, the patient's vital signs should be closely observed to check whether the infusion is unobstructed, whether there is swelling or extravasation at the puncture site, and whether there is pressure damage to the skin at the puncture site for long-term indwelling, etc., to prevent fluid exudation and pressure damage to the skin of medical devices. Because the intraosseous access is a temporary vascular access, the peripheral venous conditions need to be effectively evaluated during intraosseous infusion to grasp the best time to remove the needle. The consensus of nursing experts on the clinical application of intraosseous infusion access recommends removing the intraosseous access puncture needle within 24 hours. The incidence of osteomyelitis increases significantly after 24 hours.

[0003] The existing nursing method for the intraosseous infusion puncture site is to manually cut sterile gauze to cover the puncture point to absorb exudate and avoid pressure damage to the medical device. The cut gauze does not keep the puncture site in a sterile and closed environment, and is also prone to infection. Nursing staff need to repeatedly observe the exudate at the puncture point to avoid contamination of the gauze and failure to replace it in time, which may lead to infection. The removal time of the intraosseous infusion device cannot be accurately controlled, which increases the clinical workload and cannot meet the usage requirements. Utility Model Content

[0004] The purpose of the utility model is to provide a bone marrow infusion dressing to solve the problem that the above-mentioned background technology proposes to cover the puncture point with manually cut sterile gauze to absorb exudate and avoid pressure damage to medical equipment. The cut gauze does not put the puncture site in a sterile and closed environment, which is also easy to cause infection. Nursing staff need to repeatedly observe the exudate situation of the puncture point to avoid contamination of the gauze and failure to replace it in time to cause infection. The removal time of the bone marrow infusion device cannot be accurately controlled, which increases the clinical workload and cannot meet the use requirements.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a bone marrow cavity infusion patch, comprising a first liquid absorbing layer, and further comprising:

[0006] A second liquid absorbent layer is arranged above the first liquid absorbent layer, an adhesive layer is arranged on the upper end surface of the first liquid absorbent layer, and the second liquid absorbent layer and the first liquid absorbent layer are adhered to each other through the adhesive layer, a hollow small hole is arranged in the middle part of the first liquid absorbent layer, and tear lines are arranged on the first liquid absorbent layer, the second liquid absorbent layer and the adhesive layer, and the tear lines are connected to the hollow small hole;

[0007] The alarm mechanism is arranged above the second liquid-absorbing layer, and the alarm mechanism is engaged with the second liquid-absorbing layer.

[0008] Preferably, the alarm mechanism includes a mounting base, a timer, a liquid sensor, a buzzer and a flashing light, the liquid sensor is arranged below the mounting base, the timer, the buzzer and the flashing light are all arranged above the mounting base, and the timer, the liquid sensor, the buzzer and the flashing light are all fixedly connected to the mounting base, and the buzzer and the flashing light are electrically connected to the timer and the liquid sensor.

[0009] Preferably, a mounting recessed hole is provided at the upper end of the second liquid absorbing layer, and the depth of the mounting recessed hole is set to half of the thickness of the second liquid absorbing layer, and the mounting recessed hole is arranged corresponding to the liquid sensor.

[0010] Preferably, the lower end surface of the first liquid absorbing layer is provided with a backing adhesive, and the backing adhesive is connected to the first liquid absorbing layer as a whole.

[0011] Preferably, the cross-sections of the second liquid-absorbing layer, the adhesive layer and the back adhesive are all arranged in a circular ring shape.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model device is provided with a first liquid absorbing layer, a second liquid absorbing layer, a back adhesive, a tearing line and a hollow small hole. The first liquid absorbing layer and the second liquid absorbing layer form a double-layer structure. The tearing line can tear the bone marrow cavity infusion dressing, so that the bone marrow cavity infusion needle can be conveniently placed into the hollow small hole along the tearing line, and the bone marrow cavity infusion needle is tightly wrapped to form a sterile and airtight protection, while avoiding direct contact between the handle of the bone marrow cavity infusion needle and the patient's skin to cause pressure damage. The back adhesive fits the bone marrow cavity infusion dressing to the skin and fixes it to prevent the bone marrow cavity infusion dressing from falling off and shaking.

[0014] The utility model device sets an alarm mechanism, and the liquid sensor detects the seepage on the second liquid absorbent layer. When the seepage in the second liquid absorbent layer reaches a certain level, the buzzer and the flashing light are triggered, reminding the medical staff to replace the contaminated bone marrow cavity infusion dressing; the timer is turned on to count the usage time of the bone marrow cavity infusion dressing, which can accurately control the usage time. When the time reaches hours, the buzzer and the flashing light can also be triggered to remind the medical staff to remove the bone marrow cavity infusion device, thereby reducing the workload of clinical nursing. The alarm mechanism adopts a card-connected method, and the alarm mechanism can be removed for repeated clinical use later, saving costs and avoiding waste. BRIEF DESCRIPTION OF THE DRAWINGS
