Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, in particular to an anti-puncture blood transfusion device. Background Art

[0002] Blood transfusion is a common treatment method. It refers to a method of injecting whole blood or blood components (such as plasma, red blood cells, white blood cells or platelets, etc.) into the body through veins. Especially during surgery and rescue of trauma patients with severe blood loss, the routine process of blood transfusion is to use an infusion set to transfer the blood in the transfusion bag into the patient's body.

[0003] In the prior art, medical blood transfusion bags are disposable bags. Because blood transfusion is often used in critical situations such as rescuing patients, medical staff insert the needle into the blood transfusion bag very quickly.

[0004] During long-term use and observation, it was found that because the blood transfusion bag is made of flexible material and is easy to deform, when the tip of the needle is quickly inserted into the blood transfusion bag, it may come into contact with the inner surface of the blood transfusion bag, causing the blood transfusion bag to leak and the blood to be contaminated and unable to be used again.

[0005] To this end, the utility model provides a puncture-proof blood transfusion device. Utility Model Content

[0024] Specific examples are given below.

[0025] like Figures 1 to 3 As shown, an anti-puncture blood transfusion device described in an embodiment of the utility model comprises a blood transfusion bag body 1 and a blood transfusion bag opening 11; the bottom of the blood transfusion bag body 1 is fixedly connected to the blood transfusion bag opening 11; a sealing plug 12 is provided in the middle of the blood transfusion bag opening 11; the length of the sealing plug 12 is longer than the length of the blood transfusion needle; a first liquid guide hole 13 is opened in the middle of the sealing plug 12; the first liquid guide holes 13 are multiple groups and annularly distributed on the side wall of the sealing plug 12; a first support pad 14 is fixedly connected in the middle of the sealing plug 12; during operation, when the medical staff inserts the blood transfusion needle through the sealing plug 12, the sealing plug 12 will wrap and support the blood transfusion needle, thereby reducing the blood transfusion needle when the blood transfusion bag body 1 is deformed. The blood needle is separated from the blood transfusion bag body 1. This step is achieved by providing a sealing plug 12, which can support the blood transfusion needle when medical staff use the device to perform blood transfusion on patients, thereby reducing the possibility of the blood transfusion bag body 1 being punctured when the blood transfusion needle tip contacts the side wall of the blood transfusion bag body 1. By providing a first liquid guide hole 13, the blood inside the blood transfusion bag body 1 can smoothly enter the sealing plug 12, thereby reducing the influence of the sealing plug 12 on the blood transfusion process. By providing a first support pad 14, the blood transfusion needle can be supported when the blood transfusion needle pierces the sealing plug 12, thereby reducing the possibility of displacement and breakage of the blood transfusion needle, thereby improving the stability of the device when performing blood transfusion on patients.

[0027] Further, such as Figure 4 and Figure 5As shown, a support seat 3 is fixedly connected to the middle of the blood transfusion bag opening 11; the support seat 3 is multiple groups and is distributed in a ring at the bottom of the blood transfusion bag opening 11; a support rod 31 is provided in the middle of the support seat 3; a second support pad 32 is provided at the other end of the support rod 31; this step provides a support seat 3, a support rod 31 and a second support pad 32, so that when medical staff use this device to perform blood transfusion on patients, the blood transfusion needle can be further supported, the displacement and breakage of the blood transfusion needle can be further reduced, and the stability of this device when performing blood transfusion on patients can be further improved.

[0028] Further, such as Figure 4 and Figure 5 As shown, a sliding groove 4 is provided in the middle of the support seat 3; a sliding block 41 is slidably connected in the middle of the sliding groove 4; the end of the support rod 31 is hinged to the sliding block 41; the other end of the support rod 31 is hinged to the side wall of the second support pad 32; during operation, when the medical staff inserts the blood transfusion needle into the sealing plug 12, the blood transfusion needle is first inserted into the second support pad 32 and then into the sealing plug 12. At this time, the second support pad 32 will push the sliding block 41 to slide along the sliding groove 4 through the support rod 31, thereby guiding the movement of the blood transfusion needle. This step can support and guide the process of the blood transfusion needle piercing the sealing plug 12 by providing the sliding groove 4 and the sliding block 41, so that the blood transfusion needle can penetrate the sealing plug 12 more smoothly, reduce the situation where the blood transfusion needle obliquely penetrates the sealing plug 12 and punctures the blood transfusion bag opening 11 and the sealing plug 12, and further improve the stability of this device when performing blood transfusion on patients.

[0029] Further, such as Figure 3 and Figure 4 As shown, a first guide groove 5 is provided in the middle of the second support pad 32; a second guide groove 51 is provided at the bottom of the sealing plug 12; the first guide groove 5 corresponds to the second guide groove 51 in position; this step can guide the medical staff in the process of inserting the blood transfusion needle into the sealing plug 12 and the second support pad 32 by providing the first guide groove 5 and the second guide groove 51, thereby making it more convenient for the staff to insert the blood transfusion needle into the sealing plug 12, thereby improving the work efficiency of the medical staff.
